In what ways can PHP developers ensure that GD library is properly installed and functioning for image generation tasks?

To ensure that the GD library is properly installed and functioning for image generation tasks, PHP developers can check if the GD extension is enabled in their PHP configuration file (php.ini). They can also use the phpinfo() function to verify if the GD library is loaded and active. Additionally, developers can test GD library functions such as imagecreatetruecolor() to confirm that it is working correctly. 

// Check if GD extension is enabled
if (!extension_loaded('gd')) {
    die('GD extension is not enabled. Please enable it in your php.ini file.');
}

// Check if GD library is loaded and active
if (!function_exists('gd_info')) {
    die('GD library is not loaded. Please install or enable the GD extension.');
}

// Test GD library functions
$image = imagecreatetruecolor(100, 100);
if ($image) {
    echo 'GD library is properly installed and functioning.';
} else {
    echo 'GD library is not working correctly.';
}
