PHP 8.3.4 Released!

Phar::setStub

(PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL phar >= 1.0.0)

Phar::setStubUsed to set the PHP loader or bootstrap stub of a Phar archive

Beschreibung

public Phar::setStub(resource|string $stub, int $length = -1): bool

Hinweis:

Diese Methode des Phar-Objekts funktioniert nur wenn die php.ini-Einstellung phar.readonly auf 0 gesetzt ist, sonst wird eine PharException geworfen.

This method is used to add a PHP bootstrap loader stub to a new Phar archive, or to replace the loader stub in an existing Phar archive.

The loader stub for a Phar archive is used whenever an archive is included directly as in this example:

<?php
include 'myphar.phar';
?>

The loader is not accessed when including a file through the phar stream wrapper like so:

<?php
include 'phar://myphar.phar/somefile.php';
?>

Parameter-Liste

stub

A string or an open stream handle to use as the executable stub for this phar archive.

length

Rückgabewerte

Gibt bei Erfolg true zurück. Bei einem Fehler wird false zurückgegeben.

Fehler/Exceptions

UnexpectedValueException is thrown if phar.readonly is enabled in php.ini. PharException is thrown if any problems are encountered flushing changes to disk.

Changelog

Version Beschreibung
8.3.0 Calling Phar::setStub() with a resource and a length is now deprecated. Such calls should be replaced by: $phar->setStub(stream_get_contents($resource));

Beispiele

Beispiel #1 A Phar::setStub() example

<?php
try {
$p = new Phar(dirname(__FILE__) . '/brandnewphar.phar', 0, 'brandnewphar.phar');
$p['a.php'] = '<?php var_dump("Hello");';
$p->setStub('<?php var_dump("First"); Phar::mapPhar("brandnewphar.phar"); __HALT_COMPILER(); ?>');
include
'phar://brandnewphar.phar/a.php';
var_dump($p->getStub());
$p['b.php'] = '<?php var_dump("World");';
$p->setStub('<?php var_dump("Second"); Phar::mapPhar("brandnewphar.phar"); __HALT_COMPILER(); ?>');
include
'phar://brandnewphar.phar/b.php';
var_dump($p->getStub());
} catch (
Exception $e) {
echo
'Write operations failed on brandnewphar.phar: ', $e;
}
?>

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

string(5) "Hello"
string(82) "<?php var_dump("First"); Phar::mapPhar("brandnewphar.phar"); __HALT_COMPILER(); ?>"
string(5) "World"
string(83) "<?php var_dump("Second"); Phar::mapPhar("brandnewphar.phar"); __HALT_COMPILER(); ?>"

Its not clear in the docs but __HALT_COMPILER() is required in the stub.

If your stub has a namespace, it is used for each include that doesn't define one.

One thing I had alot of problems with, is that i can't set the stub unless I put the whole operation inside of a try/catch block!

If i remove the try/catch block it will error our and not write the stub with the content i want it to have.
