PharFileInfo->setMetaData

Description

setMetaData() should only be used to store customized data in a file that cannot be represented with existing information stored with a file. Meta-data can significantly slow down the performance of loading a phar archive if the data is large, or if there are many files containing meta-data. It is important to note that file permissions are natively supported inside a phar, although it is possible to set them with the PharFileInfo->chmod() method. As with all functionality that modifies the contents of a phar, the phar.readonly INI variable must be off in order to succeed.

Some possible uses for meta-data include passing a user/group that should be set when a file is extracted from the phar to disk. Other uses could include explicitly specifying a MIME type to return. However, any useful data that describes a file, but should not be contained inside of it may be stored.

Parameters

Examples

Example 1. A PharFileInfo->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.txt'] = 'hello';     $p['file.txt']->setMetaData(array('user' => 'bill', 'mime-type' => 'text/plain'));     var_dump($p['file.txt']->getMetaData()); } catch (Exception $e) {     echo 'Could not create/modify phar: ', $e; } ?> The above example will output: array(2) { ["user"]=> string(4) "bill" ["mime-type"]=> string(10) "text/plain" }
