      $line = fgets($fd, 8192); 
            
      if (ereg("^check:", $line)) { 

   $check = explode(",", ereg_replace("check:\ *", "", trim($line))); 
   echo count($check);
   $field = $check[0]; 
   for ($i = 1; $i < count($check); $i++) {
     [B]echo $i; [/B] 
     if (ereg("required", $check[$i])) { 
       $this->required[] = $field; 
     } else if (ereg("email-check", $check[$i])) { 
       $this->checkemail[] = $field; 
     }

      } 
}

i tried to print the value of $i (bold in code) to know what is the resutl, and the result is 1121, i cannot figure out what is mean. Please help me with this

 

You wanna know what the "count" function does? http://www.php.net/count
It counts the number of elements in an array..

   echo count($check);
   $field = $check[0]; 
   for ($i = 1; $i < count($check); $i++) {
     echo $i;  

Code (markup):

Kinda wierd code... first "echo" will tell you the number of elements and the second time it`ll progressively show you that "count"
