note 50458 added to features.file-upload

where do I find the php.ini to change the upload_max_filesize? I'm running mac os x 10.3 and php 5.03. Also I have no real knowledge about php, apache, or anything to do with software, so a detailed answer would be much appreciated. ---- Manual Page -- http://www.php.net/manual/en/features.file-upload.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+50458 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+50458&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+50458&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+50458&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+50458&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+50458&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+50458&report=yes Search -- http://master.php.net/manage/user-notes.php
