>>> Any other good ways to debug stuff in PHP and/or CI?
 
1. Always inherit a master controller]
2. define some common public $debug variables in the master controller


Display that does not screw up page formatting

Code:

// in controllers, views, etc
$this->debug = 'this is a test to see if it works';

// view
<?php
if (LOCALAHOST)
{
echo "<div style='clear:both;width:96%;margin:1em auto;border:solid 1px;overflow:auto'>";
   echo BR .$this->debug_001;
   echo BR .$this->debug_002;
   echo BR .$this->debug_003;
   echo BR .$this->debug_004;
echo '</div>/';
}
?&gt;

&lt;body&gt;
&lt;/html&gt;
