PHP function to copy a file

Last update on December 20 2024 10:21:19 (UTC/GMT +8 hours)

Write a PHP function that copies a file from one location to another.

Sample Solution:

PHP Code :

<?php
function copyFile($sourceFile, $destinationFile) {
    try {
        if (!file_exists($sourceFile)) {
            throw new Exception("Source file does not exist.");
        }

        if (!copy($sourceFile, $destinationFile)) {
            throw new Exception("Error copying the file.");
        }

        echo "File copied successfully.";
    } catch (Exception $e) {
        echo "An error occurred: " . $e->getMessage();
    }
}

// Usage:
$sourceFile = "i:/test.txt";
$destinationFile = "i:/data/test.txt";
copyFile($sourceFile, $destinationFile);
?>

Sample Output:

File copied successfully.

Explanation:

In the above exercise -

We define a function called copyFile() that takes two parameters: $sourceFile (the path of the source file) and $destinationFile (the path of the destination file).
Inside the function, we use file_exists() to check if the source file exists. If it doesn't exist, we throw an exception with the error message "Source file does not exist."
We then use the copy() function to copy the file from the source location to the destination location. If the copy operation succeeds, we display a success message. We throw an exception if the copy fails with the error message "Error copying the file."
