@Arpit That's a great solution, that's for pointing it out. The original purpose of my message, however, was to point out that you wouldn't be able to access a class's methods or members from a function defined within a method. Creating a new object won't be useful if there's specific details in the current object you need to obtain. For example, if the "$message" variable had been changed and the new message was to be echoed, creating a new object wouldn't give you access to the message you need to echo. To make better OO code I had designed a validate class with a method that used the same code repeatedly. This code was placed in a function that could be called within the method but I ran into the trouble of not being able to refer to the object's own members or methods despite still being within the object. However, I did find a more effective solution: <?php class MyClass { public $message = 'Hello'; public function MyClassFunction() { function innerFunction($this_thing) { $this_thing->echo_something(); } innerFunction($this); } public function echo_something() { echo $this->message; } } $class = new MyClass; $class->message = 'FooBar'; $class->MyClassFunction(); // Echoes 'FooBar' ?> ---- Server IP: 69.147.83.197 Probable Submitter: 76.78.201.63 ---- Manual Page -- http://www.php.net/manual/en/language.oop5.basic.php Edit -- https://master.php.net/note/edit/90072 Del: integrated -- https://master.php.net/note/delete/90072/integrated Del: useless -- https://master.php.net/note/delete/90072/useless Del: bad code -- https://master.php.net/note/delete/90072/bad+code Del: spam -- https://master.php.net/note/delete/90072/spam Del: non-english -- https://master.php.net/note/delete/90072/non-english Del: in docs -- https://master.php.net/note/delete/90072/in+docs Del: other reasons-- https://master.php.net/note/delete/90072 Reject -- https://master.php.net/note/reject/90072 Search -- https://master.php.net/manage/user-notes.php
