PHP script to rename a file

PHP File Handling: Exercise-6 with Solution

Write a PHP script to rename a file.

Sample Solution:

PHP Code :

<?php
$oldFilename = "i:/example.txt";
$newFilename = "i:/new_example.txt";

try {
    if (file_exists($oldFilename)) {
        if (rename($oldFilename, $newFilename)) {
            echo "File renamed successfully.";
        } else {
            throw new Exception("Error renaming the file.");
        }
    } else {
        throw new Exception("File does not exist.");
    }
} catch (Exception $e) {
    echo "An error occurred: " . $e->getMessage();
}
?>

Sample Output:

File renamed successfully.

Explanation:

In the above exercise -

• We have two variables: $oldFilename holds the current name of the file you want to rename, and $newFilename holds the desired new name of the file.
• Inside the try block, we first check if the old file exists using file_exists(). If it exists, we use the rename() function to rename the file. If the renaming operation is successful, we display a success message. If the renaming fails, we throw an exception with the error message "Error renaming the file."
• If the old 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().
