Whilst looking through php.net I stumbled across the following function that will print out an array in a nicely formatted table. When dealing with lots of nested array something like this makes it much easier to see all of the data contained within an array.

<?php
 function print_nice($elem,$max_level=10,$print_nice_stack=array()){
 if(is_array($elem) || is_object($elem)){
 if(in_array(&$elem,$print_nice_stack,true)){
 echo "<font color=red>RECURSION</font>";
 return;
 }
 $print_nice_stack[]=&$elem;
 if($max_level<1){
 echo "<font color=red>nivel maximo alcanzado</font>";
 return;
 }
 $max_level--;
 echo "<table border=1 cellspacing=0 cellpadding=3 width=100%>";
 if(is_array($elem)){
 echo '<tr><td colspan=2  style="background-color:#333333;"><strong><font  color=white>ARRAY</font></strong></td></tr>';
 }else{
 echo '<tr><td colspan=2 style="background-color:#333333;"><strong>';
 echo '<font color=white>OBJECT Type: '.get_class($elem).'</font></strong></td></tr>';
 }
 $color=0;
 foreach($elem as $k => $v){
 if($max_level%2){
 $rgb=($color++%2)?"#888888":"#BBBBBB";
 }else{
 $rgb=($color++%2)?"#8888BB":"#BBBBFF";
 }
 echo '<tr><td valign="top" style="width:40px;background-color:'.$rgb.';">';
 echo '<strong>'.$k."</strong></td><td>";
 print_nice($v,$max_level,$print_nice_stack);
 echo "</td></tr>";
 }
 echo "</table>";
 return;
 }
 if($elem === null){
 echo "<font color=green>NULL</font>";
 }elseif($elem === 0){
 echo "0";
 }elseif($elem === true){
 echo "<font color=green>TRUE</font>";
 }elseif($elem === false){
 echo "<font color=green>FALSE</font>";
 }elseif($elem === ""){
 echo "<font color=green>EMPTY STRING</font>";
 }else{
 echo str_replace("\n","<strong><font color=red>*</font></strong><br>\n",$elem);
 }
 }
 ?>
