PHP Exercises : Count number of lines in a file
PHP : Exercise-16 with Solution
Write a PHP script to count number of lines in a file.
Note : Store a text file name into a variable and count the number of lines of text it has.
Sample Solution: -
<?php $file = basename($_SERVER['PHP_SELF']); $no_of_lines = count(file($file)); echo "There are $no_of_lines lines in $file"."\n"; ?>
There are 5 lines in a6924e70-5a4c-11e7-b47b-99347412a245.php
basename() function: The basename(path,suffix) function is used to get the filename from a path.
count() function: The count() function is used to count the elements of an array or the properties of an object.
Note: For objects, if you have SPL installed, you can hook into count() by implementing interface Countable. The interface has exactly one method, Countable::count(), which returns the return value for the count() function.
