(PHP >= 5.3.0, PECL phar >= 1.2.0)
Phar::delMetadata — Deletes the global metadata of the phar
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.
Deletes the global metadata of the phar
returns TRUE on success, but it is better to check for thrown exception, and assume success if none is thrown.
Throws PharException if errors occur while flushing changes to disk.
Example #1 A Phar::delMetaData() example
<?php
try {
$phar = new Phar('myphar.phar');
var_dump($phar->getMetadata());
$phar->setMetadata("hi there");
var_dump($phar->getMetadata());
$phar->delMetadata();
var_dump($phar->getMetadata());
} catch (Exception $e) {
// handle errors
}
?>
上例将输出：
NULL string(8) "hi there" NULL
