If it is suitable for you to read the file piece-by-piece you can try something like this

$fd = fopen("fileName", "r");
while (!feof($fd)) {
$buffer = fread($fd, 16384); //You can change the size of the buffer according to the memory you can youse
//Process here the buffer, piece by piece
}
fclose($fd);

Read line by line using:

 $handle = fopen ( "data.txt", "r" );

 while ( ( $buffer = fgets ( $handle, 4096 ) ) !== false ) {
    // your function on line;
 }

You could read it line by line like this:

$file = fopen("data.txt", "r") or exit("Unable to open file!");

while(!feof($file)) {
  // do what you need to do with it - just echoing it out for this example
  echo fgets($file). "<br />";
}

fclose($file);
