What is the difference between imagecreate and imagecreatetruecolor in PHP when working with images?

When working with images in PHP, the main difference between imagecreate and imagecreatetruecolor is that imagecreatetruecolor creates a new true color image, while imagecreate creates a palette-based image. True color images have a higher color depth and can display a wider range of colors compared to palette-based images. Therefore, if you need to work with high-quality images or manipulate colors accurately, it is recommended to use imagecreatetruecolor.

// Create a new true color image
$image = imagecreatetruecolor($width, $height);

// Example usage:
$width = 400;
$height = 300;
$image = imagecreatetruecolor($width, $height);
