在PHP中读取大文件的最佳方法？

Question

I have to read CSV files line by line wich can be 10 to 20 Meg. file() is useless ;-) and I have to find the quickiest way.

I have try with fgets(), wich run fine, but I don't know if it read a small block each time I call it, or if it cache a bigger one and optimize file I/O. Do I have to try the fread() way, parsing EOL by myself?

Thanks Cedric

You ought to be using fgetcsv() if possible.

Otherwise, there is always fgets().
