PHP file processing in chunks

There comes a time when you too will need to process a large file that you don't want load all at once into memory. Luckily php makes this easy to do. You open a file just as usual, $f = fopen('path_to_file','r'); You can then loop through it a little bit at a time, reading in chunks. while ( ! feof($f) ) { $chunk = fread($f,1024); } If you need to process a text file in lines instead of just chunks by byte size, you can use a different function but in the same way. while ( ! feof($f) ) {... read more!
