note 80593 added to function.fopen

Hard to explain but what I would like to do is change a text file if there is a value present for instance file contains: background-color:black; and the string I am overwriting the file with contains: background-color:; I would like it not to erase the data in the file because it is blank. if the file contains: background-color:black; and the string I am overwriting the file contains: background-color:navy; Then I would like it to change that value in the file. Any tips would be great thank you ---- Server IP: 209.41.74.194 Probable Submitter: 24.247.16.43 ---- Manual Page -- http://www.php.net/manual/en/function.fopen.php Edit -- https://master.php.net/note/edit/80593 Del: integrated -- https://master.php.net/note/delete/80593/integrated Del: useless -- https://master.php.net/note/delete/80593/useless Del: bad code -- https://master.php.net/note/delete/80593/bad+code Del: spam -- https://master.php.net/note/delete/80593/spam Del: non-english -- https://master.php.net/note/delete/80593/non-english Del: in docs -- https://master.php.net/note/delete/80593/in+docs Del: other reasons-- https://master.php.net/note/delete/80593 Reject -- https://master.php.net/note/reject/80593 Search -- https://master.php.net/manage/user-notes.php
