Phar::offsetExists

    (PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL phar >= 1.0.0)

    Phar::offsetExists — Determines whether a file exists in the phar

    Description

    public Phar::offsetExists(string $localName): 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

    localName

    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)
