DarkSuperHero Posted April 20, 2009 Share Posted April 20, 2009 havnt looked over the entire code, but you probably want <?php $fp = fopen('student.xml', 'a+'); //sets the file pointed at the end of the file after, and adds any content at that point... if you want the new records at the top, then your gona have to read your file, then store it in a php variable/array, write your new information and append the old information or concatenate new and old to write it to a file....just a though... PS- From the PHP Manual: 'w' Open for writing only; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it. 'w+' Open for reading and writing; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it. w -will always replace your file contents... ;-) Link to comment https://forums.phpfreaks.com/topic/154879-editing-xml-file-using-php-help/#findComment-814648 Share on other sites More sharing options...
soak Posted April 20, 2009 Share Posted April 20, 2009 As it's XML then appending anything to it will break syntax. As you said, I think it's gonna have to be read in and amended that way, simplexml is fairly.... well.. simple if you need something to read in the XML file and append to it.
