If you have to store a few line’s of data , then you can go for files. For example consider a small application in which you need to store contact numbers of your friends and you are doing this by writing the data into a file. So what if you need to get the total number of contacts in your contact list. You may need to read the complete list and match the records to find the total number of records. i will tell you an easier way. If you are saving the contacts line by line, you can go for the total number of lines in the files. This will be the total number of contacts.

This Tutorial will help you to count the number of lines in a file.Hope this will help you and enjoy :) 

<?php
$file = "your_file.txt"; // it can be any file of your choice
$lines = count(file($file));
echo "There are $lines lines in $file";
?>
