    Here is a simple one liner to repeat a string multiple times with a separator:

    <?php
    implode    ($separator, array_fill(0, $multiplier, $input));
    ?>

    Example script:
    <?php

    // How I like to repeat a string using standard PHP functions
    $input = 'bar';
    $multiplier = 5;
    $separator = ',';
    print     implode($separator, array_fill(0, $multiplier, $input));
    print     "\n";

    // Say, this comes in handy with count() on an array that we want to use in an
    // SQL query such as 'WHERE foo IN (...)'
    $args = array('1', '2', '3');
    print     implode(',', array_fill(0, count($args), '?'));
    print     "\n";
    ?>

    Example Output:
    bar,bar,bar,bar,bar
    ?,?,?

    hi guys ,
    i've faced this example :
    <?php

    $my_head     = str_repeat("°~", 35);
    echo     $my_head;

    ?>

    so , the length should be 35x2 = 70 !!!
    if we echo it :

    <?php
    $my_head     = str_repeat("°~", 35);
    echo     strlen($my_head); // 105
    echo mb_strlen($my_head, 'UTF-8'); // 70
    ?>

    be carefull with characters and try to use mb_* package to make sure everything goes well ...

    Here is a shorter version of Kees van Dieren's function below, which is moreover compatible with the syntax of str_repeat:

    <?php
    function str_repeat_extended($input, $multiplier, $separator='')
    {
        return     $multiplier==0 ? '' : str_repeat($input.$separator, $multiplier-1).$input;
    }
    ?>

    (For the benefit of those searching the website:)

    This is the equivalent of Perl's "x" (repetition) operator, for eg.  str_repeat("blah", 8) in PHP does the same thing as "blah" x 8 in Perl.

    str_repeat does not repeat symbol with code 0 on some (maybe all?) systems (tested on PHP Version 4.3.2 , FreeBSD 4.8-STABLE i386 ).

    Use <pre>
    while(strlen($str) < $desired) $str .= chr(0);
    </pre> to have string filled with zero-symbols.

    If you want to hide a part of your password, you can use this code. It's very simple and might be required in your user management panel.

    <?php
    $password     = "12345abcdef";
    $visibleLength = 4; // 4 chars from the beginning

    echo substr($password,0,4).str_repeat("*", (strlen($password)-$visibleLength));
    ?>

    In reply to what Roland Knall wrote:

    It is much simpler to use printf() or sprintf() for leading zeros.

    <?php
       printf    ("%05d<br>\n",  1); // Will echo 00001
           sprintf("%05d<br>\n",  1); // Will return 00001
    ?>
