Are there any recommended tutorials or resources for managing images in PHP?

Managing images in PHP involves tasks such as uploading, resizing, cropping, and displaying images on a website. To handle these tasks efficiently, it is recommended to use PHP libraries like GD or Imagick. These libraries provide functions and classes to manipulate images easily. 

// Example code using GD library to resize an image
$source_image = 'path/to/source/image.jpg';
$destination_image = 'path/to/destination/image.jpg';
$max_width = 500;
$max_height = 500;

list($source_width, $source_height) = getimagesize($source_image);
$source_aspect_ratio = $source_width / $source_height;
$target_aspect_ratio = $max_width / $max_height;

if ($source_aspect_ratio > $target_aspect_ratio) {
    $new_width = $max_width;
    $new_height = $max_width / $source_aspect_ratio;
} else {
    $new_height = $max_height;
    $new_width = $max_height * $source_aspect_ratio;
}

$source_image = imagecreatefromjpeg($source_image);
$destination_image = imagecreatetruecolor($new_width, $new_height);
imagecopyresampled($destination_image, $source_image, 0, 0, 0, 0, $new_width, $new_height, $source_width, $source_height);
imagejpeg($destination_image, $destination_image);
imagedestroy($source_image);
imagedestroy($destination_image);
