Is fopen() limited by the filesystem?

Question

I wrote a program to generate large .SQL files for quickly populating very large databases. I scripted it in PHP. When I started coding I was using fopen()

Answer 1

You can write more than 2GB of data in a stream, not in a file (as the fseek internal pointer of the file is exceeding PHP limits, and streams are not usually seekable)

test.tar', 'w'); //this is a stream, no limitation here $body = str_repeat("===", 1024 * 1024); while(true) fwrite($target, $test);
