Get specific line of web page using file_get_contents

Question

I have a file test.txt over 4 lines:

This
Is
A
Test

I have a PHP script which when I run grabs the contents of this file and displays for me:

<?php $file = file_get_contents('https://www.mywebsite.com/test.txt'); echo $file; ?>

Is there any way to get a specific line from the test.txt file?

The `file` function already gives you an array of lines, so just get the specific line from that? — Niet the Dark Absol, Jul 26 '17 at 10:08
Use `file()` you get the contents of the file as an array where each item is a line. — Halcyon, Jul 26 '17 at 10:08

you could explode() with new line, like:

$string = file_get_contents('https://www.mywebsite.com/test.txt');
$stringArr = explode("\n", $string);
echo $stringArr[2]; //get the third line

or use file() which Reads entire file into an array, like:

$lines = file('https://www.mywebsite.com/test.txt');
echo $lines[2];

If the file is huge you have a lot of memory usage to read just one line. – Marek Maurizio Sep 11 '19 at 09:53

        $output = fgets($file,1); // start read file in line 1

Use file() instead:

<?php

$lines = file("file.txt");

foreach($lines as $line){

echo $line;
}
