Phar::offsetExists — Determines whether a file exists in the phar
Description
public Phar::offsetExists ( string $offset ) : bool
This is an implementation of the ArrayAccess interface allowing direct manipulation of the contents of a Phar archive using array access brackets.
offsetExists() is called whenever isset() is called.
Parameters
-
offset -
The filename (relative path) to look for in a Phar.
Return Values
Returns true if the file exists within the phar, or false if not.
Examples
Example #1 A Phar::offsetExists() example
<?php $p = new Phar(dirname(__FILE__) . '/my.phar', 0, 'my.phar'); $p['firstfile.txt'] = 'first file'; $p['secondfile.txt'] = 'second file'; // the next set of lines call offsetExists() indirectly var_dump(isset($p['firstfile.txt'])); var_dump(isset($p['nothere.txt'])); ?>
The above example will output:
bool(true) bool(false)
