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.
