PHP program to delete a file

PHP File Handling: Exercise-8 with Solution

Write a PHP program that deletes a specific file from the server.

Sample Solution:

PHP Code :

<?php
$filename = "i:/data/test.txt";

try {
    if (file_exists($filename)) {
        if (unlink($filename)) {
            echo "File deleted successfully.";
        } else {
            throw new Exception("Error deleting the file.");
        }
    } else {
        throw new Exception("File does not exist.");
    }
} catch (Exception $e) {
    echo "An error occurred: " . $e->getMessage();
}
?>

Sample Output:

File deleted successfully.

Explanation:

In the above exercise, we have a $filename variable that holds the name of the file we want to delete.

Inside the try block, we first check if the file exists using file_exists(). If it exists, we use the unlink() function to delete the file. If the deletion operation succeeds, we display a success message. If the deletion fails, we throw an exception with the error message "Error deleting the file."

If the file does not exist, we throw an exception with the error message "File does not exist."

In the catch block, we catch the exception and display an error message using $e->getMessage().
