Phar::getMetadata

Returns phar archive meta-data

Description

public mixed Phar::getMetadata(array $unserializeOptions = [])

Retrieve archive meta-data. Meta-data can be any PHP variable that can be serialized.

Caution

Accessing the meta-data will trigger deserialization, which can trigger the execution of arbitrary PHP code. Do not use this on untrusted phar archives, or configure the unserializeOptions in a secure manner.

Parameters

No parameters.

Return Values

Any PHP value that can be serialized and is stored as meta-data for the Phar archive, or null if no meta-data is stored.

Changelog

Version Description
8.0.0 The parameter unserializeOptions has been added.

Examples

Example #1 A Phar::getMetadata example

<?php
// make sure it doesn't exist
@unlink('brandnewphar.phar');
try {
    $p = new Phar(dirname(__FILE__) . '/brandnewphar.phar', 0, 'brandnewphar.phar');
    $p['file.php'] = '<?php echo "hello";';
    $p->setMetadata(array('bootstrap' => 'file.php'));
    var_dump($p->getMetadata());
} catch (Exception $e) {
    echo 'Could not modify phar:', $e;
}
?>

The above example will output:

array(1) {
  ["bootstrap"]=>
  string(8) "file.php"
}
