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

Descrição

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

Nota:

Este método requer que a configuração phar.readonly do php.ini seja definida como 0 para funcionar com objetos Phar. Caso contrário, uma exceção PharException será lançada.

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';
?>

Parâmetros

stub

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

length

Valor Retornado

Retorna true em caso de sucesso ou false em caso de falha.

Erros/Exceções

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

Registro de Alterações

Versão Descrição
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));

Exemplos

Exemplo #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;
}
?>

O exemplo acima produzirá:

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.
