PharFileInfo::delMetadata

(PHP >= 5.3.0, PECL phar >= 1.2.0)

PharFileInfo::delMetadata — Deletes the metadata of the entry

Description

代码语言:javascript
复制
public bool PharFileInfo::delMetadata ( void )

Deletes the metadata of the entry, if any.

Parameters

No parameters.

Return Values

Returns TRUE if successful, FALSE if the entry had no metadata. 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.

Errors/Exceptions

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

Examples

????var_dump($a['hi']->delMetadata());
????var_dump($a['hi']->delMetadata());
}?catch?(Exception?$e)?{
????//?handle?errors
}
