How can PHP functions be utilized effectively to streamline the process of managing and updating image files in a web application?

Managing and updating image files in a web application can be streamlined by creating PHP functions to handle common tasks such as uploading, resizing, and deleting images. By encapsulating these tasks in functions, you can easily reuse them throughout your application, making it more maintainable and efficient. 

// Function to upload an image file
function uploadImage($file, $targetDirectory) {
    $targetFile = $targetDirectory . basename($file["name"]);
    move_uploaded_file($file["tmp_name"], $targetFile);
    return $targetFile;
}

// Function to resize an image file
function resizeImage($imagePath, $width, $height) {
    // Add code to resize image here
}

// Function to delete an image file
function deleteImage($imagePath) {
    unlink($imagePath);
}
