Last update on December 20 2024 10:21:18 (UTC/GMT +8 hours)

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().
