Deleting Portion Of A File...

[Anon]

Hi. I am trying to write a news posting script that uses PHP and a text file to store the data, and the text file is added to the page using an include command. I have adding data to the file working, I'm just not sure how to delete it. When the file is added, it's added like this:

<!--$title (name of news headline)-->
News and everything else collected from the form
<!--End $title-->

The $title is replaced with the title collected from the form. I want to be able to select the story or type the name of it, and have it delete everything in the text file that is between the two HTML comment lines. How would I do this? Thanks

The only way to do this with a text file is to rewrite the entire file.
In brief:

• Open a new (temporary) filename for writing.
• Open the existing file for reading
• Copy each line from the input to the output, except...
• when you read the desired title, stop copying lines
• after you've seen the next End title, start copying again.
• close both files.
• rename the temp file to the permanent name (if your OS doesn't support destructive renames, you'll have to also delete the original file first.)
