note 68243 added to function.preg-replace

In my php files I always write all content that should be echoed, into 1 variabele. Is it possible to optimize that variabele, so the source code (right mouse button --> view source) is as little as possible? remove double spaces remove tabs remove white lines remove html comments and so on, so that you get 1 long line of html output does any1 know a way to do this? ---- Server IP: 194.109.193.119 Probable Submitter: 80.61.105.156 ---- X-Spam-Status: No, hits=3.4 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER, REMOVE_REMOVAL_NEAR autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.preg-replace.php Edit -- http://master.php.net/note/edit/68243 Del: integrated -- http://master.php.net/note/delete/68243/integrated Del: useless -- http://master.php.net/note/delete/68243/useless Del: bad code -- http://master.php.net/note/delete/68243/bad+code Del: spam -- http://master.php.net/note/delete/68243/spam Del: non-english -- http://master.php.net/note/delete/68243/non-english Del: in docs -- http://master.php.net/note/delete/68243/in+docs Del: other reasons-- http://master.php.net/note/delete/68243 Reject -- http://master.php.net/note/reject/68243 Search -- http://master.php.net/manage/user-notes.php
