Counting preg match results

[graham23s]

Hey Guys,

i was wondering if there was a way to count how many preg match results you get back

my code is:

PHP Code:

$matchesfound = preg_match('/subject="/', $nsubject, $matchfound); 


any help would be great

cheers

$matchesfound will have either 0 or 1, since preg_match will only find one and then stop. If you use preg_match_all() then you would get all of the matches in the subject.

Hi Mate,

when i echo the variable out i get:

PHP Code:

00000000000000000000000000000000000000000000000000000000000000000000 


im wanting to count the number of 0's , iv even tried strlen but nothin

cheers

Are you using it in a loop or something? Post your code..

Hi Mate,

yep its in a loop which returns the info i want when done , the number of 0's represent files which i was after the number of

code:

PHP Code:

     foreach($xml->{"file"} as $nfile) {
     
        $nposter = (string) trim($nfile['poster']);
        $nposter = ($nposter);
                    
        $ndate = 0 + trim($nfile['date']);
                    
        $nsubject = (string) trim($nfile['subject']);
        // To find num of segments in subject:
        $nsubjsegs = 0 + subj_seg($nsubject);
        
        // To find out if Par or not
        $npar = (stristr($nsubject, "par2")?0:1);
        
        $nsubject = ($nsubject);
                    
        $groups = array();
        foreach($nfile->groups->group as $group) {
              $groups[] = (string) trim($group);
        }
        $ngroups = (serialize($groups));
                               
        $nsegcount = 0;
        $nsize = 0;
        foreach($nfile->segments->segment as $segment) {
              $nbytes = 0 + trim($segment['bytes']);
              $nsize += $nbytes;
              $nsegcount++; 
        }
        
     //=====================================================================================//
     // Easy way to count number of files preg_match all the subject=" and e-voila :)
     //=====================================================================================//
        
      $matchesfound = preg_match_all('/subject="/', $nsubject, $matchfound);
        
      echo $matchesfound;
      
             
      } 


thanks mate

It's not finding subject=" in the string, try echo($nsubject . '<br />'); before preg_match_all().

[graham23s]

ahh yeah thats true, i just realised i need to actually search in the .xml file rather than kust the subject (although the 0's and 1's were giving me back the amount of subject='s there was in the file

can a preg_match search in an xml file at all?

thanks mate
