Question

I want to do a str_replace for a HTML String, everytime find a match item the value will increase as well.

$link = 1;

$html = str_replace($this->link, $link, $html);

This would replace all in once, and with same string $link, i would like the $link increase every time it found an match. is it possible?

Thanks very much

If I understand you correctly (you want each match replaced with growing integer), it would seem the comments on the question encouraging you to use preg_replace_callback would be correct:

$str = 'Hello World';
$cnt = 0;

function myCallback ( $matches ) {
  global $cnt;
  return ++$cnt;
}

// He12o Wor3d
echo preg_replace_callback( '/\l/', 'myCallback', $str );
