RE: [PHP] HELP please quickly

I'm currently looking at this. This particular code creates a file 10-20 times the size of the orginial file. A minor alteration of this code copies the file to the results file. Basically I think the problem is, is in the preg_match, and I can't think of why that would die when it is placed back into the code. Any thoughts.

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); } } } ?> -----Original Message----- From: Didier McGillis [mailto:codesmoker@hotmail.com] Sent: 22 January 2003 14:33 To: php-general@lists.php.net 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.

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 -----Original Message----- From: Rick Emery [mailto:remery@emeryloftus.com] Sent: 22 January 2003 13:57 To: Didier McGillis Cc: php-general@lists.php.net Subject: Re: [PHP] HELP please quickly In that case, I don't know of any PHP classes to help you. ----- Original Message ----- From: "Didier McGillis" <codesmoker@hotmail.com> To: <remery@emeryloftus.com> Sent: Wednesday, January 22, 2003 7:53 AM Subject: Re: [PHP] HELP please quickly 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.

this

chore. ----- Original Message ----- From: "Didier McGillis" <codesmoker@hotmail.com> To: <php-general@lists.php.net> Sent: Wednesday, January 22, 2003 7:21 AM Subject: [PHP] HELP please quickly 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? _________________________________________________________________ MSN 8 helps eliminate e-mail viruses.
