Variable watch in PHP#1
Does PHP have the ability to watch a variable (or object property) and run a function when its value changes, similar to Gecko's Javascript watch function?

Re: Variable watch in PHP#3
XDebugmight have this, but I don't know for sure.If you're trying to debug a member variable on an object, you can use overloading:public function __set($var, $val){ if ($var == 'interesting') { echo "$var set to: "; var_dump($val); } $this->$var = $val;}

Re: Variable watch in PHP#4
According to PHP docs (us3.php.net/manual/en/language.oop5.overloading.php) : "__set() is run when writing data to inaccessible members." It doesn't filter all member accesses.

Re: Variable watch in PHP#5
This would be possible when using XDebug along side an IDE like eclipse.

Re: Variable watch in PHP#6
Do you want to detail what the ultimate goal is? E.g. just being able to watch a var, or something else which you need the watch for?
