Reading huge file line by line in PHP

Question

In Java I use Scanner to read text file line by line, so memory usage will be very low, because only one line is in memory once. Is there similar method in PHP?

Answer 1

use fseek, fgets

$handle = fopen("/tmp/uploadfile.txt", "r") or die("Couldn't get handle");
if ($handle) {
    while (!feof($handle)) {
        $line = fgets($handle);
        // Process line here..
    }
    fclose($handle);
}

Answer 2

fgets($fileHandle) is what you're looking for. You get the file handle using fopen("filename.txt", "r"), and close it with fclose($fileHandle).
