memory improvement

[majick777]

explode line crashed the script on my install, which made me realize it is very memory intensive on a large file like this.
instead my alternative is to write the file and use fgets to process it line by line. (hopefully doesn't affect the regex?)

@majick777 Could you check this with the Project browscap/brpwscap-php as well? browscap/browscap-php is the successor of this project and better maintained.

Please also check the following things:

• You need write access to the cache dir
• You need a lot of Memory to create the cache (>= 256MB)
• Is there any error in your error log?

ah sorry just saw I never got back to this have been too busy to check or log it on the other project... just on those notes you mentioned:

• write access is fine as I did test writes to the directory at the time
• tested on my VPS hosting with 4gb memory and 256M limit
• no error whatsoever in the log at the time which is what made me curious, it simply crashed at the explode line which I thought was strange...
  ...it is probably a memory thing which is why I logged this to begin with, I can't test the difference in memory usage myself as it crashed but I think it would be quite significant and allow users with much less memory available to compile updates.
  ... will test again when I can.
