PHP - Manual: PharFileInfo::delMetadata

2025-04-28

PharFileInfo::delMetadata

(PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL phar >= 1.2.0)

PharFileInfo::delMetadataDeletes the metadata of the entry

说明

public PharFileInfo::delMetadata(): true

Deletes the metadata of the entry, if any.

参数

No parameters.

返回值

总是返回 true。 As with all functionality that modifies the contents of a phar, the phar.readonly INI variable must be off in order to succeed if the file is within a Phar archive. Files within PharData archives do not have this restriction.

错误/异常

Throws PharException if errors occurred while flushing changes to disk, and BadMethodCallException if write access is disabled.

示例

示例 #1 A PharFileInfo::delMetaData() example

<?php
try {
$a = new Phar('myphar.phar');
$a['hi'] = 'hi';
var_dump($a['hi']->delMetadata());
$a['hi']->setMetadata('there');
var_dump($a['hi']->delMetadata());
var_dump($a['hi']->delMetadata());
} catch (
Exception $e) {
// handle errors
}
?>

以上示例会输出:

bool(false)
bool(true)
bool(false)
