[SOLVED] removal of an object

[purencool]

hi

 

When I created an object in php does the php engine when finished with the script delete the object out of memory straight away or does it store in a similar way that a session cookie is kept on the server and removes it later on like the Java engine has a garbage disposal?

 

thanks purencool

PHP 5 introduces a destructor concept similar to that of other object-oriented languages, such as C++. The destructor method will be called as soon as all references to a particular object are removed or when the object is explicitly destroyed or in any order in shutdown sequence.

This is not relevant to php5 at all.  PHP has always had page script -- all memory is garbage collected once a script is done executing.  What has changed recently is the conditiions under which garbage collection inside php is done.  PHP is now more aggressive in doing garbage collection during the execution of a script than it was previously. 

 

You could certainly think of it in the same way you might think of the way a jvm manages memory, however, in the web context, php has no way to persist data beyond a single http request/response.  This is in fact why sessions are such a necessary mechanism.
