Note Submitter: dragon_rage4@hotmail.com ---- A problem I ran into was confusion between array_merge and array_push. array_push works on all variable types except arrays themselves. In those cases, array_merge is the road to follow. Example: # The following does not work because # you cannot push an array onto another $myFirstArray = array("a", "b"); $mySecondArray = array("c", "d"); array_push($myFirstArray, $mySecondArray); // This pushes "Array" onto $myFirstArray, not "cd" for ($i = 0; $i < count($myFirstArray); $i++) { print $myFirstArray[$i]; // This will print abArray } # However, array_merge() does the trick $myThirdArray = array("a", "b"); $myFourthArray = array("c", "d"); $myThirdArray = array_merge($myThirdArray, $myFourthArray); // Merges two arrays into a single array for ($i = 0; $i < count($myThirdArray); $i++) { print $myThirdArray[$i]; // This will print abcd }
