str_repeat — Repeat a string
stringThe string to be repeated.

Number of time the string string should be
repeated.

If the times is set to 0, the function
will return an empty string.
Returns the repeated string.
Example #1 str_repeat() example
<?php
echo str_repeat("-=", 10);
?>The above example will output:

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

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) - $before; // 0.032104Here is a shorter version of Kees van Dieren's function below, which is moreover compatible with the syntax of str_repeat:
<?php
function str_repeat_extended($input, $multiplier, $separator='')
{
return $multiplier==0 ? '' : str_repeat($input.$separator, $multiplier-1).$input;
}
?>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 ...
