You need to use fopen + fgets instead of file Didier McGillis wrote:
Cool. Thanks for the information. I try and organize my thoughts like that as well. I dont really need to delete anything, mostly move and copy.
One problem I have run into is my second file seems to be too big. In just doing a simple count the first file was fine, found my 470 lines. The second file is 7.1MB and seems to fail telling me "Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 81 bytes)"
So it seems to be on hurrdle at a time.

I'm pretty new to PHP so I can't help you with the code per se, but how
about as an outline;
Open the first file and read values into an array.
Open the 2nd file and read in the first line.
Compare each value in the array to see if it occurs in the line from the 2nd
file you just read in.
If it occurs then write that value to the 3rd file
Repeat until the array ends
File functions are here -> http://www.php.net/manual/en/ref.filesystem.php -
the only one I can't see is the ability to delete a line in a file - at
least without creating another holding file....very messy that way
tho...I'll keep looking.
As an exercise to myself I'll try and recreate it using the 2 example files
below....dunno how long it'll take me tho ;o)
Good luck
Nick

In that case, I don't know of any PHP classes to help you.

No. The numbers are coming from two text files. The first text file is the
file that I need to compare against the second file, and if I find one match
in the second file, I need to move it to the third file.
