Buying need a php programmer for editing some lines ...... $5

hi

i am trying to insert preg_match in IF statement after that replace it by preg_replace.

So First ... if $post matching any image urls then replace it with (img src) else replace it

with href ...

            $post = 'hello .. see that pic http://dogandcat.com/images/cat2.jpg  and that pic http://www.helpinghomelesscats.com/images/cat1.jpg for more info plz click here http://google.com or here http://msn.com/music';
    
        $pattrenlink='/((([http]{3,9}:(?:\/\/)?)(?:[-;:&=\+\$,\w]+@)?[A-Za-z0-9.-]+|(?:www.|[-;:&=\+\$,\w]+@)[A-Za-z0-9.-]+)((?:\/[\+~%\/.\w-_]*)?\??(?:[-\/+=&#?;%@,.\w_]*)#?(?:[\w]*)?))/';
    
        $pattrenimage='/(http(s?):)(.+)(?:jpg|jpeg|gif|png)/';
        
    
    
    
        if (preg_match( $pattrenimage, $post))
        
                           {
    $html_links = preg_replace($pattrenimage, '<a href="$0" target="_blank" ><img src="$0" width="200" height="150"></a>', $post);
                           }
        
        else
                           {
        	$html_links =preg_replace($pattrenlink, '<a href="$0" target="_blank">$0</a>', $post);
        	               }
    
    echo $html_links ;

PHP:

notice : all both regex work fine ... ( $pattrenlink macth any url) and ($pattrenimage match any

image url).. (test it http://regexr.com?31sgg)

but here it replace the image url only ??!! what i want is to replace the image with (img src= ) tags and replace url with href tags ???
so any help for $5 in paypal ?
