var_dump/print_r

Sometime agoi, I realized a method equivalent to print_r, but with a much better support to avoid circular reference, better color, and so on I think it could be interesting to add a directory Error or Debug, and put this method there: Rigth now, it is a method, but it would be pretty easy to call it this way: VAR_DUMP::var_dumpr(...); What do you think? /** * Equivalent of var_dump, but much nicer * Dump to the screen the content of a variable, object or array * If we are working with an object, we will see also the list of the methods * to avoid cycle pointer reference, it is possible to specify a maximum depth * * @param mixed $a Variable to check in * @param optional string $pre Used to ident correctly the levels,

*                             what to put before

* @param optional integer $limitdepth What is the limit depth * @param optional boolean $firstcall Must be set to true if it is the first

*                                   time you call this method

* @param optional string $before What to put before beginning the process * @param optional string $before What to put after finishing the process * * @author Stephane Huther <shuther@bigfoot.com> */ /** @constant String VAR_DUMPR_LIMIT_OVER limit over*/ define ('VAR_DUMPR_LIMIT_OVER','(LIMIT DEPTH OVER)'); /** @constant String VAR_DUMPR_NO_ELEMENT no more element*/ define ('VAR_DUMPR_NO_ELEMENT','NO ELEMENT'); function var_dumpr(&$a,$pre='', $limitdepth='5', $firstcall=true, $before='<font color="#0033FF" face="Verdana" size="1">', $after='</font><br/>') { if (0==$limitdepth) { printf('%s %s %s<br/>',$pre, $a, VAR_DUMPR_LIMIT_OVER); return; } if ($firstcall) print $before; $c=gettype($a); $toshow=false; switch ($c) { case 'array': printf('%sArray<br/>', $pre); $pre=$pre .
