(PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL phar >= 1.2.0)
Phar::delMetadata — Deletes the global metadata of the phar
注意:
此方法需要 將 php.ini 中的
phar.readonly設為0以適合 Phar 對象. 否則, 將拋出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.
示例 #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
}
?>
以上例程會(huì )輸出：
NULL string(8) "hi there" NULL
