Which php function reads a single line from a file?

I want to read a file line by line, but without completely loading it in memory.

My file is too large to open in memory, and if try to do so I always get out of memory errors.

The file size is 1 GB.

You can use the fgets[] function to read the file line by line:

$handle = fopen["inputfile.txt", "r"];
if [$handle] {
    while [[$line = fgets[$handle]] !== false] {
        // process the line read.
    }

    fclose[$handle];
}

if [$file = fopen["file.txt", "r"]] {
    while[!feof[$file]] {
        $line = fgets[$file];
        # do same stuff with the $line
    }
    fclose[$file];
}

You can use an object oriented interface class for a file - SplFileObject //php.net/manual/en/splfileobject.fgets.php [PHP 5 >= 5.1.0]
