What steps can be taken to ensure that the GD library is properly installed and functioning in PHP?

To ensure that the GD library is properly installed and functioning in PHP, you can check if the GD extension is enabled in your PHP configuration file (php.ini) and verify that the GD library is installed on your server. You can also test the GD library by running a simple script that uses GD functions to manipulate images. 

<?php
// Check if GD extension is enabled
if (!extension_loaded('gd')) {
    echo 'GD extension is not enabled';
} else {
    echo 'GD extension is enabled';
}

// Check if GD library is installed
if (!function_exists('gd_info')) {
    echo 'GD library is not installed';
} else {
    echo 'GD library is installed';
}

// Test GD library by creating a simple image
$width = 200;
$height = 200;
$image = imagecreatetruecolor($width, $height);
$bgColor = imagecolorallocate($image, 255, 255, 255);
$textColor = imagecolorallocate($image, 0, 0, 0);
imagestring($image, 4, 50, 50, 'Test Image', $textColor);
header('Content-type: image/png');
imagepng($image);
imagedestroy($image);
?>
