# Phar::offsetExists

(no version information, might be only in CVS)

Phar::offsetExists -- determines whether a file exists in the phar

## Description

bool Phar::offsetExists ( string offset )

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.

## Liste de paramètres

`offset`

  The filename (relative path) to look for in a Phar.

## Valeurs de retour

Returns `TRUE` if the file exists within the phar, or `FALSE` if not.

## Exemples

Exemple 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'])); ?>`

L'exemple ci-dessus va afficher :

    bool(true)
    bool(false)
