(PHP 5 >= 5.3.0, PHP 7, PECL phar >= 1.2.0)
Phar::delMetadata — Deletes the global metadata of the phar
Note:
此方法需要 将 php.ini 中的 phar.readonly 设为 0 以适合 Phar 对象. 否则, 将抛出PharException.
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
}
?>
以上例程会输出：
NULL string(8) "hi there" NULL
