PHP - Manual: Phar::delMetadata
2024-12-21
(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 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.
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
}
?>
以上例程会输出:
NULL string(8) "hi there" NULL
