Re: Variable Troubleshooting Code

Hi, some pretty natives php functions exists to do the job : var_export — Outputs or returns a parsable string representation of a variable debug_zval_dump — Dumps a string representation of an internal zend value to output var_dump — Dumps information about a variable print_r — Prints human-readable information about a variable echo '<pre>'; print_r( array | object ); echo '</pre>'; Regards.
