str_replace with regex

Question

I think this has been done a million times but I can't get the expression right.

I need to str_replace an <input> element and everything between the So capture the id and the name enz...

So I thought:

<?php 
    $regex = '<input(.*?)>';
    $replacement = '<select>';
    $content = '<input id="id" name="name"/>text';
    $result = str_replace($regex, $replacement, $content);
    echo $result;
?>

I know this won't work but I think this should be the right way.

Anyone?

[str_replace](http://php.net/manual/en/function.str-replace.php) support regex? no!, try [preg_replace](http://php.net/manual/en/function.preg-replace.php) or xpath — rray, Oct 02 '15 at 13:51

It has no sense to edit your question after others gave you the solution. Better search next time. — phaberest, Oct 02 '15 at 14:05

Worse than using `mysql_` functions or Dreamweaver as IDE, surely is parsing HTML with regular expressions. — al'ein, Oct 02 '15 at 14:35

Just use preg_replace:

<?php 
$regex = '#<input(.*?)>#';
$replacement = '<select>';
$content = '<input id="id" name="name"/>text';
$result = preg_replace($regex, $replacement, $content);
echo $result;

@PedroLobito delimiters at `$regex` and `preg_replace` instead of `str_replace`. – al'ein Oct 02 '15 at 14:31
