php - How to replace a whole div with an other with preg_replace regEx


i don't get it how to replace a div with an other in PHP preg_replace

$string ='
  <div id="myid">this has to be replaced</div>
  <p>here is something</p>
  <div id="any">any text not to be replaced</div>

if i do

$string = preg_replace('/<div id=\"myid\">.*<\/div>/','anything',$string);

it does not work and i don't get why?!




Since yourregex is working fine I suspect that you didn't assign the return value ofpreg_replace to any variables.

$string = preg_replace('/<div id=\"myid\">.*<\/div>/','anything',$string);

should work.

After you edited your question:

As @Felix Kling mentioned,.* is greedy, that means it matches everything until the last match. You can use the non-greedy quantifier (ie..*?). The following should work:

$string = preg_replace('/<div id=\"myid\">.*?<\/div>/','anything',$string);
