PHP String Exercises: Extract the file name from the specified string

Sample Solution:

PHP Code:

<?php
$path = 'www.example.com/public_html/index.php'; // Assigns a string containing a file path to the variable $path
$file_name = substr(strrchr($path, "/"), 1);     // Finds the last occurrence of '/' in $path and extracts the substring after it
echo $file_name."\n";                            // Outputs the extracted file name "index.php"
?>

Output:

index.php

Explanation:

The above PHP code extracts the file name from a given file path stored in the variable '$path'. It does this by using the "strrchr(") function to find the last occurrence of the '/' character in the path and then using "substr()" to extract the substring after that character. Finally, it echoes the extracted file name.
