PHP function to copy a file

PHP File Handling: Exercise-7 with Solution

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."
