Are there any potential issues or limitations when using the imagestring function in PHP for text centering?

One potential issue when using the imagestring function in PHP for text centering is that it does not have built-in support for centering text horizontally within an image. To solve this, you can calculate the x-coordinate for the starting position of the text based on the image width and text length. 

// Create a new image
$image = imagecreate(200, 50);

// Set the background color
$bgColor = imagecolorallocate($image, 255, 255, 255);

// Set the text color
$textColor = imagecolorallocate($image, 0, 0, 0);

// Set the text to be centered
$text = "Centered Text";

// Calculate the x-coordinate for centering the text
$textWidth = imagefontwidth(5) * strlen($text);
$x = (imagesx($image) - $textWidth) / 2;

// Add the centered text to the image
imagestring($image, 5, $x, 20, $text, $textColor);

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

// Free up memory
imagedestroy($image);
