Debugging PHP
|
Debuggers generally use a W:Stack trace. This can be approximated by using print and die statements in sections of code. The combination of print_r and func_get_args allows you to return an array of args that a function was called with;
print_r(func_get_args());
Casting an object of an array builds an array of the properties, mapping property names to values. e.g.
class Person {
var $name = "Fred";
var $age = 35;
}
$o = new Person;
$a = (array) $o
print_r($a);
outputs;
- Array
- (
- [name] => Fred
- [age] => 35
- )

From Sven/Notes, Extension:Fasta.php; <php>
- Logging to an article from within the MW environment
function logAdd($article,$msg) { $ts = $GLOBALS['wgLang']->timeanddate(wfTimestampNow(),true); $la = new Article(Title::newFromText($article)); $la->quickEdit($la->getContent()."\n*$ts: $msg"); }
- Logging to a file
function logFile($file, $msg) { $fh = fopen($file,'a'); $ts = $GLOBALS['wgLang']->timeanddate(wfTimestampNow(),true); if(is_array($msg)) $msg = print_r($msg, true); fwrite($fh, "\n$ts: $msg"); } </php>
PHP errors
To see PHP errors, add this to the very top of LocalSettings.php: <php> error_reporting(E_ALL); ini_set("display_errors", 1); </php>
