(PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL phar >= 1.2.0)
PharFileInfo::delMetadata — Deletes the metadata of the entry
Deletes the metadata of the entry, if any.
No parameters.
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.
Throws PharException if errors occurred while flushing changes to disk, and BadMethodCallException if write access is disabled.
Example #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
}
?>
The above example will output:
bool(false) bool(true) bool(false)
