[PHP] HELP please quickly

[Didier McGillis]

Here is a brief description of what I want to do. I want to use PHP to grab a list of numbers in one file. Check it against a bigger file and strip the ones that match out of the bigger file, into a "holding" file.


so here is what it might look like.

file1.txt
456789
456790
456791
456792
456793
456794
....

file2.log
some time stamp
code=001;number=456784;name=blahblah;date=012403;
some time stamp
code=001;number=456785;name=blahblah;date=012403;
some time stamp
code=001;number=456786;name=blahblah;date=012303;
some time stamp
code=001;number=456789;name=blahblah;date=012503;
some time stamp
code=001;number=456789;name=blahblah;date=012503;
some time stamp
code=001;number=456789;name=blahblah;date=012503;
some time stamp
code=001;number=456789;name=blahblah;date=012503;
some time stamp
code=001;number=456789;name=blahblah;date=012503;
some time stamp
code=001;number=456790;name=blahblah;date=012603;
some time stamp
code=001;number=456791;name=blahblah;date=012703;

notice there might be more then one of the same number, I only need one so I need to ignore the rest, rip out the time stamp, which is a seperate line.

file3.txt
code=001;number=456789;name=blahblah;date=012503;
code=001;number=456790;name=blahblah;date=012603;
code=001;number=456791;name=blahblah;date=012703;

can anyone help, any suggestions?
