I managed this bit of code, but I doubt it does exactly what you want, but
it's a start. And just to add to it I couldn't get the preg_match to work -
so that needs sorting. I'm at work, so I'm afraid I can't spend any more
time right now on this. If anyone can help on the preg_match bit (it just
needs to compare/match 2 strings) then could you add to this ? I looked at
the preg_match function on the php site, but I couldn't make head nor tail
of it :o/
Good luck with it
Nick
<?php
// load file1.txt into array
$file1 = file ('./file1.txt');
// open file2.log for read only
$file2 = fopen ("./file2.log", "r");
// open results.txt for write
$results = fopen ("./results.txt", "w");
while (!feof($file2)) {
$buffer = fgets($file2, 4096);
foreach ($file1 as $line_num => $line) {
//if (preg_match ("/$line/", "$buffer")) <- CAN'T GET THIS
TO WORK ;o(
{ fwrite ($results, $buffer); }
}
}
?>

Subject: RE: [PHP] HELP please quickly
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.
