Excepciones

Tabla de contenidos

PHP 5 tiene un modelo de excepciones similar al de otros lenguajes de programación. Una excepción puede ser lanzada ("thrown"), y atrapada ("catched") dentro de PHP. El código puede estar dentro de un bloque try para facilitar la captura de excepciones potenciales. Cada bloque try debe tener al menos un bloque catch o finally correspondiente.

El objeto lanzado debe ser una instancia de la clase Exception o una subclase de Exception. Intentar lanzar un objeto que no lo sea resultará en un Error Fatal de PHP.

catch

Se pueden usar múltiples bloques catch para atrapar diferentes clases de excepciones. La ejecución normal (cuando no es lanzada ninguna excepción dentro del bloque try) continuará después del último bloque catch definido en la sencuencia. Las excepciones pueden ser lanzadas ("thrown") (o relanzadas) dentro de un bloque catch.

Cuando una excepción es lanzada, el código siguiente a la declaración no será ejecutado, y PHP intentará encontrar el primer bloque catch coincidente. Si una excepción no es capturada, se emitirá un Error Fatal de PHP con un mensaje "Uncaught Exception ..." ("Excepción No Capturada"), a menos que se haya definido un manejador con set_exception_handler().

finally

En PHP 5.5 y posterior, se puede utilizar un bloque finally después o en lugar de los bloques catch. El código de dentro del bloque finally siempre se ejecutará después de los bloques try y catch, independientemente de que se haya lanzado una excepción o no, y antes de que la ejecución normal continúe.

Notas

Nota:

Las funciones internas de PHP utilizan principalmente la Información de Errores, sólo las extensiones Orientadas a objetos modernas utilizan excepciones. Sin embargo, los errores se pueden traducir a excepciones simplemente con ErrorException.

Sugerencia

La Biblioteca Estádar de PHP (SPL) proporciona un buen número de excepciones internas.

Ejemplos

Ejemplo #3 Lanzar una Excepción

<?php
function inverso($x) {
    if (!
$x) {
        throw new 
Exception('División por cero.');
    }
    return 
1/$x;
}

try {
    echo 
inverso(5) . "\n";
    echo 
inverso(0) . "\n";
} catch (
Exception $e) {
    echo 
'Excepción capturada: ',  $e->getMessage(), "\n";
}

// Continuar la ejecución
echo 'Hola Mundo\n';
?>

El resultado del ejemplo sería:

0.2
Excepción capturada: División por cero.
Hola Mundo

Ejemplo #4 Manejo de excepciones con un bloque finally

<?php
function inverse($x) {
    if (!
$x) {
        throw new 
Exception('División por cero.');
    }
    return 
1/$x;
}

try {
    echo 
inverse(5) . "\n";
} catch (
Exception $e) {
    echo 
'Excepción capturada: ',  $e->getMessage(), "\n";
finally {
    echo 
"Primer finally.\n";
}

try {
    echo 
inverse(0) . "\n";
} catch (
Exception $e) {
    echo 
'Excepción capturada: ',  $e->getMessage(), "\n";
finally {
    echo 
"Segundo finally.\n";
}

// Continuar ejecución
echo 'Hola Mundo\n';
?>

El resultado del ejemplo sería:

0.2
Primer finally.
Excepción capturada: División por cero.
Segundo finally.
Hola Mundo

Ejemplo #5 Excepciones anidadas

<?php

class MiExcepción extends Exception { }

class 
Prueba {
    public function 
probar() {
        try {
            try {
                throw new 
MiExcepción('foo!');
            } catch (
MiExcepción $e) {
                
// relanzarla
                
throw $e;
            }
        } catch (
Exception $e) {
            
var_dump($e->getMessage());
        }
    }
}

$foo = new Prueba;
$foo->probar();

?>

El resultado del ejemplo sería:

string(4) "foo!"

When catching an exception inside a namespace it is important that you escape to the global space:

<?php
namespace SomeNamespace;

class
SomeClass {

  function
SomeFunction() {
   try {
    throw new
Exception('Some Error Message');
   } catch (\
Exception $e) {
   
var_dump($e->getMessage());
   }
  }

}
?>

If a TRY has a FINALLY, a RETURN either in the TRY or a CATCH won't terminate the script. Code in the same block after the RETURN will not be executed, and the RETURN itself will be "copied" to the bottom of the FINALLY block to be executed.

a RETURN in the FINALLY block will override value(s) returned from the TRY or a CATCH block.

An EXIT or a DIE always terminate the script after themselves.

code 1

<?php
   
function foo(){
       
$bar = 1;
        try{
            throw new
Exception('I am Wu Xiancheng.');
        }catch(
Exception $e){
            return
$bar;
           
$bar--; // this line will be ignored
       
}finally{
           
$bar++;
        }
    }
    echo
foo(); // 2
?>

code 2

<?php
   
function foo(){
       
$bar = 1;
        try{
            throw new
Exception('I am Wu Xiancheng.');
        }catch(
Exception $e){
            return
$bar;
           
$bar--; // this line will be ignored
       
}finally{
           
$bar++;
            return
$bar;
        }
    }
    echo
foo(); //2
?>

code 3

<?php
   
function foo(){
       
$bar = 1;
        try{
            throw new
Exception('I am Wu Xiancheng.');
        }catch(
Exception $e){
            return
$bar;
           
$bar--; // this line will be ignored
       
}finally{
            return
100;
        }
    }
    echo
foo(); //100

Please don't do something like this:

<?php
try {
   
// experimental stuff to check whether something works
} catch(\Throwable $e) {
    return
false;
}
finally {
    return
true;
}
?>

Well, it is allowed syntax, it is bad practice, because once it hits the exception block, finally won't be called(because it exits the scope). Finally was invented to prevent duplicated code after one operation, regardless whether it was successful(for example closing the connection to a server). This way, you don't have any duplicated code. So you don't need to use this structure.

In case your E_WARNING type of errors aren't catchable with try/catch you can change them to another type of error like this:

<?php
    set_error_handler
(function($errno, $errstr, $errfile, $errline){
            if(
$errno === E_WARNING){
               
// make it more serious than a warning so it can be caught
               
trigger_error($errstr, E_ERROR);
                return
true;
            } else {
               
// fallback to default php error handler
               
return false;
            }
    });

    try {
           
// code that might result in a E_WARNING
   
} catch(Exception $e){
           
// code to handle the E_WARNING (it's actually changed to E_ERROR at this point)
   
} finally {
           
restore_error_handler();
    }
?>

If you intend on creating a lot of custom exceptions, you may find this code useful.  I've created an interface and an abstract exception class that ensures that all parts of the built-in Exception class are preserved in child classes.  It also properly pushes all information back to the parent constructor ensuring that nothing is lost.  This allows you to quickly create new exceptions on the fly.  It also overrides the default __toString method with a more thorough one.

<?php
interface IException
{
   
/* Protected methods inherited from Exception class */
   
public function getMessage();                 // Exception message
   
public function getCode();                    // User-defined Exception code
   
public function getFile();                    // Source filename
   
public function getLine();                    // Source line
   
public function getTrace();                   // An array of the backtrace()
   
public function getTraceAsString();           // Formated string of trace
   
    /* Overrideable methods inherited from Exception class */
   
public function __toString();                 // formated string for display
   
public function __construct($message = null, $code = 0);
}

abstract class
CustomException extends Exception implements IException
{
    protected
$message = 'Unknown exception';     // Exception message
   
private   $string;                            // Unknown
   
protected $code    = 0;                       // User-defined exception code
   
protected $file;                              // Source filename of exception
   
protected $line;                              // Source line of exception
   
private   $trace;                             // Unknown

   
public function __construct($message = null, $code = 0)
    {
        if (!
$message) {
            throw new
$this('Unknown '. get_class($this));
        }
       
parent::__construct($message, $code);
    }
   
    public function
__toString()
    {
        return
get_class($this) . " '{$this->message}' in {$this->file}({$this->line})\n"
                               
. "{$this->getTraceAsString()}";
    }
}
?>

Now you can create new exceptions in one line:

<?php
class TestException extends CustomException {}
?>

Here's a test that shows that all information is properly preserved throughout the backtrace.

<?php
function exceptionTest()
{
    try {
        throw new
TestException();
    }
    catch (
TestException $e) {
        echo
"Caught TestException ('{$e->getMessage()}')\n{$e}\n";
    }
    catch (
Exception $e) {
        echo
"Caught Exception ('{$e->getMessage()}')\n{$e}\n";
    }
}

echo
'<pre>' . exceptionTest() . '</pre>';
?>

Here's a sample output:

Caught TestException ('Unknown TestException')
TestException 'Unknown TestException' in C:\xampp\htdocs\CustomException\CustomException.php(31)
#0 C:\xampp\htdocs\CustomException\ExceptionTest.php(19): CustomException->__construct()
#1 C:\xampp\htdocs\CustomException\ExceptionTest.php(43): exceptionTest()
#2 {main}

Custom error handling on entire pages can avoid half rendered pages for the users:

<?php
ob_start
();
try {
   
/*contains all page logic
    and throws error if needed*/
   
...
} catch (
Exception $e) {
 
ob_end_clean();
 
displayErrorPage($e->getMessage());
}
?>

catch doesn't check for the existence of the Exception class, so avoid typo.

<?php
  
class MyException extends Exception
  
{
      ...
   }

   try
   {
      throw new
MyException(...);
   }
   catch (
MuException $e) // <--- typo
  
{
      ...
   }
?>

You WON'T get
   Fatal error: Class MuException could not be loaded ...

You WILL get
   Fatal error: Uncaught exception 'MyException' ...

Using a return statement inside a finally block will override any other return statement or thrown exception from the try block and all defined catch blocks.   Code execution in the parent stack will continue as if the exception was never thrown. 

Frankly this is a good design decision because it means I can optionally dismiss all thrown exceptions from 1 or more catch blocks in one place, without having to nest my whole try block inside an additional (and otherwise needless) try/catch block.

This is the same behavior as Java, whereas C# throws a compile time error when a return statement exists inside a finally block.  So I figured it was worth pointing out to PHP devs who may not have any exposure to finally blocks or how other languages do it.

<?php

function asdf()
{
    try {
        throw new
Exception('error');
    }
    catch(
Exception $e) {
        echo
"An error occurred";
        throw
$e;
    }
   
finally {
               
//This overrides the exception as if it were never thrown
       
return "\nException erased";
    }
}

try {
    echo
asdf();
}
catch(
Exception $e) {
    echo
"\nResult: " . $e->getMessage();
}
?>

The output from above will look like this:

    An error occurred
    Exception erased

Without the return statement in the finally block it would look like this:

    An error occurred
    Result: error

‘Normal execution (when no exception is thrown within the try block, *or when a catch matching the thrown exception’s class is not present*) will continue after that last catch block defined in sequence.’

‘If an exception is not caught, a PHP Fatal Error will be issued with an “Uncaught Exception …” message, unless a handler has been defined with set_exception_handler().’

These two sentences seem a bit contradicting about what happens ‘when a catch matching the thrown exception’s class is not present’ (and the second sentence is actually correct).

Sometimes you want a single catch() to catch multiple types of Exception. In a language like Python, you can specify multiple types in a catch(), but in PHP you can only specify one. This can be annoying when you want handle many different Exceptions with the same catch() block.

However, you can replicate the functionality somewhat, because catch(<classname> $var) will match the given <classname> *or any of it's sub-classes*.

For example:

<?php
class DisplayException extends Exception {};
class
FileException extends Exception {};
class
AccessControl extends FileException {}; // Sub-class of FileException
class IOError extends FileException {}; // Sub-class of FileException

try {
  if(!
is_readable($somefile))
     throw new
IOError("File is not readable!");
  if(!
user_has_access_to_file($someuser, $somefile))
     throw new
AccessControl("Permission denied!");
  if(!
display_file($somefile))
     throw new
DisplayException("Couldn't display file!");

} catch (
FileException $e) {
 
// This block will catch FileException, AccessControl or IOError exceptions, but not Exceptions or DisplayExceptions.
 
echo "File error: ".$e->getMessage();
  exit(
1);
}
?>

Corollary: If you want to catch *any* exception, no matter what the type, just use "catch(Exception $var)", because all exceptions are sub-classes of the built-in Exception.

If you are using a namespace, you must indicate the global namespace when using Exceptions.
<?php
namespace alpha;
function
foo(){
    throw new \
Exception("Something is wrong!");
   
// throw new Exception(""); will fail
}

try {
   
foo();
} catch( \
Exception $e ) {
   
// catch( Exception $e ) will give no warning, but will not catch Exception
   
echo "ERROR: $e";
}

?>

The "finally" block can change the exception that has been throw by the catch block.

<?php
try{
        try {
                throw new \
Exception("Hello");
        } catch(\
T  }
    catch(
Exception $e$e->getMessage();" 'atch binn";
    }nbsp;           throw nn>$e-
        } c/span>fonally {
                <
$e->getMessage();" 'onally ;
    }nbsp;           throw new \
Exception("HBye);
        } br />} catch (<
T  }
    catch(
Exception $e$e->getMessage();" 'atch (outn";
&
?>

The output fs:

&ello"'atch binbr />&ello"'onally &Bye'atch (out/span>
