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 
$multiplier=='' str_repeat($input.$separator$multiplier-1).$input;
}
?>

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

<?php
implode
($separatorarray_fill(0$multiplier$input));
?>

Example script:
<?php

// How I like to repeat a string using standard PHP functions
$input 'bar';
$multiplier 5;
$separator ',';
print 
implode($separatorarray_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 (...)'
$args = array('1''2''3');
print 
implode(','array_fill(0count($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 ...

Damien Bezborodov , yeah but execution time of your solution is 3-5 times worse than str_replace.

<?php

function spam($number) {
    return 
str_repeat('test'$number);
}

function 
spam2($number) {
    return 
implode(''array_fill(0$number'test'));
}

//echo spam(4);
$before microtime(true);
for (
$i 0$i 100000$i++) {
   
spam(10);
}
echo 
microtime(true) - $before "\n"// 0.010297
$before microtime(true);
for (
$i 0$i 100000$i++) {
   
spam2(10);
}
echo 
microtime(true) - $before// 0.032104
