How can one troubleshoot PHP scripts that fail to display text using imagettftext() function?

The issue of PHP scripts failing to display text using the imagettftext() function may be due to incorrect font paths or incorrect font sizes specified in the function. To troubleshoot this, ensure that the font file path is correct and the font size is appropriate for the image dimensions. 

// Specify the font file path
$font = 'path/to/font.ttf';

// Specify the text to be displayed
$text = 'Hello, World!';

// Set the font size
$font_size = 20;

// Create an image
$image = imagecreate(200, 100);

// Set the text color
$text_color = imagecolorallocate($image, 255, 255, 255);

// Display the text on the image
imagettftext($image, $font_size, 0, 10, 50, $text_color, $font, $text);

// Output the image
header('Content-type: image/png');
imagepng($image);

// Free up memory
imagedestroy($image);
