Read a particular line from a text file in PHP

I can put the code snippet only. But as it is CodeSpeedy and we always try to give you the easiest understandable code snippet so I will explain everything step by step with an easy example.

We are here to read a specific line from a text file right?

So let’s create a text file first.

Hello I am from line no 1
Hi I am from line no 2
hello again I am from line no 3
Hey I am from line no 4

Okay, that’s enough for this example text file.

Just save the above lines as a text file. You can put any file name. But in this example, I am saving it as mytextfile.txt

Now just make a PHP file to read the text of a particular line

<?php
$my_text_file = "mytextfile.txt";
$all_lines = file($my_text_file);
echo $all_lines[2];
?>

Output:

hello again I am from line no 3

Explanation:

Here we have used one PHP inbuilt function that is file().

The file() function actually returns an array. So here $all_lines variable holds the whole text file as an array.
In order to get a particular line, we need to use the array index. Array indexing starts with zero. So if we wish to get the text of line no 3 then we need to use $all_lines[2]
