proc_open

(PHP 4 >= 4.3.0, PHP 5, PHP 7)

proc_open Executa um comando e abre ponteiros para entrada e saída

Descrição

resource proc_open ( string $cmd , array $descriptorspec , array &$pipes [, string $cwd [, array $env [, array $other_options ]]] )

proc_open() é similar a popen() mas provê uma grau de controle muito maior sobre a execução do programa.

Parâmetros

cmd

O comando a executar

descriptorspec

Uma matriz indexada aonde a chave representa o número do descritor e o valor representa como o PHP passará este descritor para o processo filho. 0 é stdin, 1 é stdout, enquanto 2 é stderr.

Os pipes suportados atualmente são file e pipe .

Os números dos descritores de arquivos não estão limitados a 0, 1 e 2 - você pode especificar qualquer número de descritor válido e ele será passado para o processo filho. Isto permiteao seu script interoperar com outros scripts que sejam executados como "co-processos". Em particular, isto é útil para passar senhas para programas como PGP, GPG e openssl de uma maneira mais segura. Também é útil para ler informações do estado providos por esses programas em descritores auxiliares.

pipes

Sera definido como uma matriz indexada de ponteiros de arquivos que corresponde aos pipes do lado do PHP que são criados.

cwd

O diretório inicial de trabalho para o comando. Este deve ser um caminho absoluto, ou NULL se você quer usar o valor padrão (o diretório de trabalho do processo PHP atual)

env

Uma matriz de variáveis de ambiênte para o comando que será executado, ou NULL para usar o mesmo ambiênte que o processo PHP atual.

other_options

Permite a você definir opções adicionais. Opções atualmente suportadas incluem:

  • suppress_errors (apenas windows): suprime os erros gerados por esta função quando estiver definido como TRUE
  • bypass_shell (apenas windows): ignora o shell cmd.exe quando esta definido como TRUE
  • context: contexto de stream usado ao abrir arquivos (criado com stream_context_create())
  • binary_pipes: abre os pipes em modo binário, ao invés de usar o stream_encoding

Valor Retornado

Retorna um recurso representando o processo, o qual deve ser liberado usando proc_close() quando você terminou de utiliza-lo. Em caso de falha retorna FALSE.

Changelog

Versão Descrição
6.0.0 Adicionado as opções context e binary_pipes no parâmetro other_options.
5.2.1 Adicionada a opção bypass_shell ao parâmetro other_options.
5.0.0 Adicionado os parâmetros cwd, env e other_options.

Exemplos

Exemplo #1 Um exemplo proc_open()

<?php
$descriptorspec 
= array(
   
=> array("pipe""r"),  // stdin is a pipe that the child will read from
   
=> array("pipe""w"),  // stdout is a pipe that the child will write to
   
=> array("file""/tmp/error-output.txt""a"// stderr is a file to write to
);

$cwd '/tmp';
$env = array('some_option' => 'aeiou');

$process proc_open('php'$descriptorspec$pipes$cwd$env);

if (
is_resource($process)) {
    
// $pipes now looks like this:
    // 0 => writeable handle connected to child stdin
    // 1 => readable handle connected to child stdout
    // Any error output will be appended to /tmp/error-output.txt

    
fwrite($pipes[0], '<?php print_r($_ENV); ?>');
    
fclose($pipes[0]);

    echo 
stream_get_contents($pipes[1]);
    
fclose($pipes[1]);

    
// It is important that you close any pipes before calling
    // proc_close in order to avoid a deadlock
    
$return_value proc_close($process);

    echo 
"command returned $return_value\n";
}
?>

O exemplo acima irá imprimir algo similar à:

Array
(
    [some_option] => aeiou
    [PWD] => /tmp
    [SHLVL] => 1
    [_] => /usr/local/bin/php
)
command returned 0

Notas

Nota:

Compatibilidade com Windows: Descritores além do 2(stderr) são tornados disponíveis ao processo filho como manipuladores herdados, mas já que a arquitetura Windows não associa números de descritores de arquivos com os manipuladores de baixo nível, o processo filho (ainda) não tem meios de acessar estes manipuladores. Stdin, stdout e stderr funcionam como esperado.

Nota:

Se você precisa de um pipe de processo de apenas uma direção, use popen() ao invés, já que é muito mais fácil de usar.

Veja Também

  • popen() - Abre um processo como ponteiro de arquivo
  • exec() - Executa um programa externo
  • system() - Executa um programa externo e mostra a saída
  • passthru() - Executa um programa externo e mostra a saída crúa
  • stream_select() - Runs the equivalent of the select() system call on the given arrays of streams with a timeout specified by tv_sec and tv_usec
  • O operador backtick

The call works as should. No bugs.
But. In most cases you won't able to work with pipes in blocking mode.
When your output pipe (process' input one, $pipes[0]) is blocking, there is a case, when you and the process are blocked on output.
When your input pipe (process' output one, $pipes[1]) is blocking, there is a case, when you and the process both are blocked on own input.
So you should switch pipes into NONBLOCKING mode (stream_set_blocking).
Then, there is a case, when you're not able to read anything (fread($pipes[1],...) == "") either write (fwrite($pipes[0],...) == 0). In this case, you better check the process is alive (proc_get_status) and if it still is - wait for some time (stream_select). The situation is truly asynchronous, the process may be busy working, processing your data.
Using shell effectively makes not possible to know whether the command is exists - proc_open always returns valid resource. You may even write some data into it (into shell, actually). But eventually it will terminate, so check the process status regularly.
I would advice not using mkfifo-pipes, because filesystem fifo-pipe (mkfifo) blocks open/fopen call (!!!) until somebody opens other side (unix-related behavior). In case the pipe is opened not by shell and the command is crashed or is not exists you will be blocked forever.

It took me a long time (and three consecutive projects) to figure this out.  Because popen() and proc_open() return valid processes even when the command failed it's awkward to determine when it really has failed if you're opening a non-interactive process like "sendmail -t".

I had previously guess that reading from STDERR immediately after starting the process would work, and it does... but when the command is successful PHP just hangs because STDERR is empty and it's waiting for data to be written to it.

The solution is a simple stream_set_blocking($pipes[2], 0) immediately after calling proc_open().

<?php

    $this
->_proc = proc_open($command, $descriptorSpec, $pipes);
   
stream_set_blocking($pipes[2], 0);
    if (
$err = stream_get_contents($pipes[2]))
    {
      throw new
Swift_Transport_TransportException(
       
'Process could not be started [' . $err . ']'
       
);
    }

?>

If the process is opened successfully $pipes[2] will be empty, but if it failed the bash/sh error will be in it.

Finally I can drop all my "workaround" error checking.

I realise this solution is obvious and I'm not sure how it took me 18 months to figure it out, but hopefully this will help someone else.

NOTE: Make sure your descriptorSpec has ( 2 => array('pipe', 'w')) for this to work.

Interestingly enough, it seems you actually have to store the return value in order for your streams to exist. You can't throw it away.

In other words, this works:

<?php
$proc
=proc_open("echo foo",
  array(
    array(
"pipe","r"),
    array(
"pipe","w"),
    array(
"pipe","w")
  ),
 
$pipes);
print
stream_get_contents($pipes[1]);
?>

prints:
foo

but this doesn't work:

<?php
proc_open
("echo foo",
  array(
    array(
"pipe","r"),
    array(
"pipe","w"),
    array(
"pipe","w")
  ),
 
$pipes);
print
stream_get_contents($pipes[1]);
?>

outputs:
Warning: stream_get_contents(): <n> is not a valid stream resource in Command line code on line 1

The only difference is that in the second case we don't save the output of proc_open to a variable.

Note that when you call an external script and retrieve large amounts of data from STDOUT and STDERR, you may need to retrieve from both alternately in non-blocking mode (with appropriate pauses if no data is retrieved), so that your PHP script doesn't lock up. This can happen if you waiting on activity on one pipe while the external script is waiting for you to empty the other, e.g:

<?php
$read_output
= $read_error = false;
$buffer_len  = $prev_buffer_len = 0;
$ms          = 10;
$output      = '';
$read_output = true;
$error       = '';
$read_error  = true;
stream_set_blocking($pipes[1], 0);
stream_set_blocking($pipes[2], 0);

// dual reading of STDOUT and STDERR stops one full pipe blocking the other, because the external script is waiting
while ($read_error != false or $read_output != false)
{
    if (
$read_output != false)
    {
        if(
feof($pipes[1]))
        {
           
fclose($pipes[1]);
           
$read_output = false;
        }
        else
        {
           
$str = fgets($pipes[1], 1024);
           
$len = strlen($str);
            if (
$len)
            {
               
$output .= $str;
               
$buffer_len += $len;
            }
        }
    }
   
    if (
$read_error != false)
    {
        if(
feof($pipes[2]))
        {
           
fclose($pipes[2]);
           
$read_error = false;
        }
        else
        {
           
$str = fgets($pipes[2], 1024);
           
$len = strlen($str);
            if (
$len)
            {
               
$error .= $str;
               
$buffer_len += $len;
            }
        }
    }
   
    if (
$buffer_len > $prev_buffer_len)
    {
       
$prev_buffer_len = $buffer_len;
       
$ms = 10;
    }
    else
    {
       
usleep($ms * 1000); // sleep for $ms milliseconds
       
if ($ms < 160)

Please note that if you plan to spawn multiple processes you have to save all the results in different variables (in an array for example). If you for example would call $proc = proc_open..... multiple times the script will block after the second time until the child process exits (proc_close is called implicitly).

If you are, like me, tired of the buggy way proc_open handles streams and exit codes; this example demonstrate the power of pcntl, posix and some simple output redirection:

<?php
$outpipe
= '/tmp/outpipe';
$inpipe = '/tmp/inpipe';
posix_mkfifo($inpipe, 0600);
posix_mkfifo($outpipe, 0600);

$pid = pcntl_fork();
