Question

I am parse some html code with curl. some site’s html source like:

<div id="content">
    some words
</div>
<?    
    $box_social['dimensioni']="80";
        $box_vota=array();
    $box_vota["novideo"]='';
    $box_vota["nofoto"]='';
    $box_vota["id_articolo"]='1003691';
    include($_SERVER['DOCUMENT_ROOT']."/incs/box_social.php");    
?>
<div id="footer">
   some words
</div>

How to remove php short tags from html source? I need

<div id="content">
    some words
</div>
<div id="footer">
   some words
</div>

And I use preg_replace('/<\?(.*?)\?>/','',$html);, but the php short tag part still there.

Answer 1

This regex matches your case:

$html = htmlspecialchars(preg_replace('/<\?([\w\W]*)\?>/','',$html));
$html = htmlspecialchars(preg_replace('/<\?(.*)\?>/s','',$html));

This also matches if more than one block of PHP is there:

$html = htmlspecialchars(preg_replace('/<\?([^\?>]*)\?>/','',$html));

FROM PHP.NET

s (PCRE_DOTALL)
If this modifier is set, a dot metacharacter in the pattern matches all characters, including newlines. Without it, newlines are
excluded. This modifier is equivalent to Perl’s /s modifier. A
negative class such as [^a] always matches a newline character,
independent of the setting of this modifier.
