TRICKY CHALLENGE: is there a way to check if $object->variable exists without automatically triggering the functionality of __get in case the variable doesn't exist? TRADITIONAL WAY: <?php $object = new someClass(); // imagine someClass uses the Magic Method "__get" if($object->variable){ // do something } else { // "__get" has inevitably been triggered :-( } ?> Ok, above we have the conventional way to check if a variable exists inside the object, the problem is that sometimes we DON'T WANT TO TRIGGER __GET in case the statement returns false! ALTERNATIVE WAY: <?php if(array_key_exists( 'variable', get_object_vars($object) ) ){ // do something } else { // "__get" has no idea what is going on, i think it is still asleep :-) } ?> you can even turn this into a function or something ---- Server IP: 69.147.83.197 Probable Submitter: 189.30.251.63 ---- Manual Page -- http://www.php.net/manual/en/language.oop5.overloading.php Edit -- https://master.php.net/note/edit/97110 Del: integrated -- https://master.php.net/note/delete/97110/integrated Del: useless -- https://master.php.net/note/delete/97110/useless Del: bad code -- https://master.php.net/note/delete/97110/bad+code Del: spam -- https://master.php.net/note/delete/97110/spam Del: non-english -- https://master.php.net/note/delete/97110/non-english Del: in docs -- https://master.php.net/note/delete/97110/in+docs Del: other reasons-- https://master.php.net/note/delete/97110 Reject -- https://master.php.net/note/reject/97110 Search -- https://master.php.net/manage/user-notes.php
