Jason Carson wrote: Yes, I am trying to write stuff to a file with PHP but in between the tags and without deleting what is already in the file. The only way is to read the file into memory, manipulate it there, and then rewrite it. Use a regex to get rid of the last closing tag, append your new lines to it, and then write it. You probably want to do it atomic or you can end up with occasional issues (broken pages that requested the file you are writing before it is finished being written) and I don't know if php can do that. Again that's where using a non php config file that is parsed by php. You can make your edits, save the file to cache (IE APC) and then write it. Files that need its contents can get it out of cache and only need to read it from file if it isn't cached. Since you cache it before writing, it will be in cache while it is being written. Another advantage to not using php for the file, you can validate the values before setting/using them and handle problems appropriately in your code rather than have a completely broken site because the script that wrote the file had a bug causing a ; not to be written under certain conditions. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

The current industry standard is a combination of text editor and keyboard, but there are many options. More specifically, are you trying to write to a PHP file *with* PHP?

Jason Carson wrote: Hello everybody, How would I go about writing stuff to a file but in between the tags? Example, say I have config.php as follows... How would I go about adding stuff at the end of the file, but before the ?> tag? IMHO that's kind of dangerous. Better to have an xml file - and read it into a DOM object via DOMDocument. Then you can add things to the DOM by making them children of the config node - and write the whole dom back to file. That way your web app does not have write permission to a file that gets executed, and you can potentially cache the DOMDocument object in memory so it doesn't have to read from file every page load to get your settings (not tried that yet myself but I don't see why you couldn't). -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Writing to a file
The classic method is: 1.) read the whole file into an array of strings. 2.) search for the last line 3.) insert a string BEFORE the last line. 4.) write back the whole file to the same name Classic file handling does allow you to append to the end of a file, or recreate as a whole. Usually these types of editing must be done in memory, because file handling does not allow inserts, deletes.

Remove the ?> tag - it's not required if it's the last thing in the file. -Stuart -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I think you should try fclose() the file before you die!

Because you already wrote $counter back to the file there in line 3.
Nowhere in those three lines did you increment the counter before doing
the write.

Don't even bother with that previous answer. You have what you want to write in a string, $new. Read the file and put that into another string, $previous.
