PHP GDライブラリ - 画像を表示

Question

画像に別の画像を表示したいだけです。

私は情報が書かれており、彼のアバターを見せたいと思います。

HTML要素が記述されています。これはイメージであることをサーバーにどのように伝えることができますか？どのように画像を取得するためにimagecreatefromstringとのfile_get_contentsを使用する方法について

<?php 

header('Content-Type: image/png'); 

$jpg_image = imagecreatefrompng('sign/sign.png'); 

$white = imagecolorallocate($jpg_image, 255, 255, 255); 

$font_path = 'sign/font.ttf'; 

$posts = "424"; 

$followers = "2424"; 

$following = "41241241"; 

$image = "<img src='https://scontent.cdninstagram.com/t51.2885-19/s320x320/14719833_310540259320655_1605122788543168512_a.jpg'>"; 

$image2 = imagejpeg($image); 


imagettftext($jpg_image, 50, 0, 170, 240, $white, $font_path, $posts); 

imagettftext($jpg_image, 50, 0, 800, 240, $white, $font_path, $followers); 

imagejpeg($jpg_image, 0, 1130, 240, $image, $white); 

imagettftext($jpg_image, 50, 0, 1630, 240, $white, $font_path, $following); 


imagepng($jpg_image); 

imagedestroy($jpg_image); 
?>
