How can PHP developers avoid adding unnecessary effects or watermarks when dynamically adding text to images?

To avoid adding unnecessary effects or watermarks when dynamically adding text to images in PHP, developers can ensure that the text is added in a subtle and non-intrusive manner. This can be achieved by using a transparent background for the text, choosing a font size and color that blends well with the image, and positioning the text in a way that does not distract from the main content of the image.

// Load the image
$image = imagecreatefromjpeg('image.jpg');

// Set the font color and size
$textColor = imagecolorallocate($image, 255, 255, 255);
$fontSize = 20;

// Add text to the image
imagettftext($image, $fontSize, 0, 10, 20, $textColor, 'arial.ttf', 'Your text here');

// Output the image
header('Content-Type: image/jpeg');
imagejpeg($image);

// Free up memory
imagedestroy($image);
