How can beginners effectively use PHP functions like ImageString and ImageTTFText for image manipulation?

To effectively use PHP functions like ImageString and ImageTTFText for image manipulation, beginners should first create a new image using imagecreatetruecolor, then set the font size, color, and text alignment using ImageTTFText. Finally, save or output the modified image using imagepng or imagejpeg. 

// Create a blank image
$image = imagecreatetruecolor(400, 200);

// Set font size and color
$font_size = 20;
$font_color = imagecolorallocate($image, 255, 255, 255);

// Add text using TrueType font
$text = "Hello, World!";
$font_path = 'arial.ttf'; // Path to a TrueType font file
imagettftext($image, $font_size, 0, 10, 100, $font_color, $font_path, $text);

// Save the modified image
imagepng($image, 'output.png');

// Output the modified image
header('Content-Type: image/png');
imagepng($image);
imagedestroy($image);
