Deleting row in text file?
Posted 20 July 2006 - 08:30 PM
Currently, I need to create a script that deletes a select row from a text file, at each \n character, that would mark a row...
Now, let's say I have this for information... (in a text file)
I'd want my script to display that, which it does, but I'd also want the row number returned to the script, so it would know which row to delete.
Any ideas how I'd do this? I could just use write, and re-write all the rows updated to the file, but if there is a way to just delete a row, then I'd like to take that path.

<?php $content=file_get_contents("file.txt"); $rows=explode("\n",$content); ?>
Now, every row is in the $rows array. So, to access the first row you would do $rows. To access the second row you would do $rows. And, any other row after that, you know what to do.

Now, I have one more question...
In a foreach loop, is it possible to exclude the last row? (Which is, blank.)
