Phar::offsetExists — Determines whether a file exists in the phar
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.
localName
The filename (relative path) to look for in a Phar.
Example #1 A Phar::offsetExists() example
<?php$p = new Phar(dirname(__FILE__) . '/my.phar', 0, 'my.phar');$p['firstfile.txt'] = 'first file';$p['secondfile.txt'] = 'second file';// the next set of lines call offsetExists() indirectlyvar_dump(isset($p['firstfile.txt']));var_dump(isset($p['nothere.txt']));?>
The above example will output:
bool(true) bool(false)
