Question

This will not validate because of the output from print_r, is it not supposed to be used “on a site” or do one have to format it in a certain way?

  <?php
   $stuff1 = $_POST["stuff1"];//catch variables
   $stuff2 = $_POST["stuff2"]; 
   $stuff3 = $_POST["stuff3"]; 
   $myStuff[0] = $stuff1;//put into array
   $myStuff[1] = $stuff2;
   $myStuff[2] = $stuff3;

   print_r($myStuff);

  ?>

print_r() is mainly designed as a helpful tool for developers, not for actual production use in a manner that end-users would see. Thus, you shouldn’t really be trying to validate it – if you’re at the stage where you’re trying to get stuff to validate, you shouldn’t be using print_r anyway.
