[RESOLVED] Splitting Text Files?

netfrugal

Is there a way to split large text files with PHP?

Can you define what you mean by "split"? If you simply want to split it up line by line, just use the [man]file/man function. If you want to split it up in some other manner, we'll need more info.

Good question.

I mean taking a large tab-delimited file with thousands of rows of information.

Can the file() function take that text file and split it up into smaller text files with a maximum amount of rows per text file?

Basically I want to write a simple text file splitter, and I know it's more detailed than using just 1 php function. But, I thought I'd ask if it's possible, and what functions can be used to do it.

thanks!

   $line = fgets($source);

             die("Can't create output file");
   }
   fputs($out, $line);
}
fclose($out);

I am getting the second die() error message.

It may be an permissions issue, I will play around with it and see if that's the case.

Looks like it is a permissions issue!

In the error logs I get this:

fopen(part_1.txt): failed to open stream: Permission denied in /var/www/html/site.com/split_files.php on line 23

But I chmod the folder to 777 and it worked just fine!

Awesome!
