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 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

?,?,?

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;

}

?>

Needed a function to repeat a string with a separator.



<?php

/**

 * Repeats <tt>$string</tt> <tt>$multiplier</tt> times, separated with <tt>$sep</tt>.

 *

 * str_repeat_sep('?', ',', 3) ==> "?,?,?"

 * str_repeat_seap('..', '/', 3) ==> "../../.."

 *

 * @param string $string

 * @param string $sep

 * @param int $multiplier

 * @return string

 */

function str_repeat_sep($string, $sep, $multiplier) {

  $ret = "";

  for($i=0;$i<$multiplier;$i++) {

    if ($i) $ret.=$sep;

    $ret.=$string;

  }

  return $ret;

}

?>

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

?>

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.

Note that the first argument is parsed only once, so it's impossible to do things like this:



echo str_repeat(++$i, 10);



The example will produce 10 times the value of $i+1, and will not do a cycle from $i to $i+10.

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.
