[wp-hackers] quick request for fix idea (print_r and returning)

[David Schlosnagle]

It sounds like you are looking for a function to return the contents
of a variable. From <http://www.php.net/print_r>, here is a function
in the user contributed notes at the bottom that looks like it will
work for you. This isn't my code, so I haven't tested it, but it
should give you a start.

<?php
   function Dump($vardump,$key = false,$level=0,$return=""){       
  
       //make layout
       for ($i = 0;$i<$level;$i++) $return .= "\t";
       if ($level != 0) $key = $key." =>";
      
       //look for objects
       if (is_object($vardump))
           $return .= $key." ".get_class($vardump)." ".$vardump."\n";
       else
           $return .= $key." ".$vardump."\n";
      
       //look recursief
       switch(gettype($vardump)){
           case "object":
               $vars=(array)get_object_vars($vardump);
               foreach($vars as $key => $value)
                   //for in a object
                   //$this->Dump($value,$key,$level+1,&$return);
                   //for normal function you can use
                   Dump($value,$key,$level+1,&$return);
           break;
           case "array":
               foreach ($vardump as $key => $value)
                   //for in a object
                   //$this->Dump($value,$key,$level+1,&$return);
                   //for normal function you can use
                   Dump($value,$key,$level+1,&$return);
           break;
       }
       //return everything
       if ($level == 0) return $return;
   }
?>
