Nice PHP print_r Formatted Table Function
Posted on Jan 16 2012 by Matthew Jakeman
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); } } ?>
