RE: [PHP] Simple (?) var_dump question [summarization]
WHOW .. that bool parameter never found it's way to me .. untill now .. appears to be a new one in PHP4.3. So, now let's summarize the var dumping and export functions: print_r($mixed, [bool return]) - Produces quite readable output var_export($mixed, [bool return]) - Produces valid php code var_dump($mixed, $mixed1, ..) - Produces quite unreadable and invalid php code - tells you exactly what the type of your variable is Think I got it quite right and complete, didn't I?

RE: [PHP] Simple (?) var_dump question
aiaiaia ... you are all pretty right, for another function was forged. var_export has a "return" flag as second argument where print_r and var_dump both have other variables as second (and third, and fourth, and sixth) .. So you can do: $logger->debug(var_export($Var), true)); which will log the var to your log. -> -Oorspronkelijk bericht- -> Van: Chris Boget [mailto:[EMAIL PROTECTED] -> Verzonden: vrijdag 12 september 2003 18:34 -> Aan: CPT John W.

Not true. You have to use output buffering for print_r() as well. print_r() just returns a boolean value. It'd be nice if you could have it so that either (or both) print_r() or var_dump() could return a value w/o using buffering...

You need to use output buffering to capture the output with var_dump. Or you can use print_r(), which will give you a similar output and can be returned to a varible. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
