Phar::setMetadata

(PHP >= 5.3.0, PECL phar >= 1.0.0)

Phar::setMetadata — Sets phar archive meta-data

Description

public void Phar::setMetadata ( mixed $metadata )

Note:

This method requires the php.ini setting phar.readonly to be set to 0 in order to work for Phar objects. Otherwise, a PharException will be thrown.

Phar::setMetadata() should be used to store customized data that describes something about the phar archive as a complete entity. PharFileInfo::setMetadata() should be used for file-specific meta-data. Meta-data can slow down the performance of loading a phar archive if the data is large.

Some possible uses for meta-data include specifying which file within the archive should be used to bootstrap the archive, or the location of a file manifest like » PEAR's package.xml file. However, any useful data that describes the phar archive may be stored.

Parameters

metadata: Any PHP variable containing information to store that describes the phar archive

Return Values

No value is returned.

Examples

Example #1 A Phar::setMetadata() 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 create and/or modify phar:', $e;
}
?>

The above example will output:

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