file_get_contents and file_put_contents with large files

Question

I\'m trying to get file contents, replace some parts of it using regular expressions and preg_replace and save it to another file:

$content = file_get_conten         


        

Answer 1

I'm pretty sure you're hitting some regex limit. Heck, some time ago I hit a limit with 1000 chars... with 60Mb of input I bet you will likely hit regex limits everywhere also with really simple patterns. I will try at least to simplify it as much as possible, making it ungreedy with .*? instead of .* if possible.

To get more information, just check the return value of preg_last_error().

Answer 2

You're probably running out of memory. What's the memory_limit set to? (phpinfo() will tell you). You may be able to increase the memory limit like:

ini_set('memory_limit','128M');

Answer 3

I've had max/limit issues with file_put_contents.

No idea what the limits might be, but using fwrite solved my troubles and I put down the bottle.
