如何从url获取图像并将其保存在mysql中作为BLOB？ PHP

Question

清除问题，我使用php作为我的后端，我想获取url图像的内容然后将其作为BLOB类型插入mysql中？这该怎么做 ？

我试过这段代码：

<?php
$servername = "localhost";
$username = "root";
$password = "111";
$dbname = "111";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);


$data = file_get_contents("https://images-na.ssl-images-amazon.com/images/M/MV5BMTI3ODc2ODc0M15BMl5BanBnXkFtZTYwMjgzNjc3._V1_UX182_CR0,0,182,268_AL_.jpg");


    $sql =  "UPDATE employee SET realPhoto='".$data."' WHERE id= 2";

if ($conn->query($sql) === TRUE) {
echo  ("true");

 } else {

echo  ("false");
 }

?>

我想要这样的东西而不使用Imagick类，怎么样？

Answer 1

"INSERT INTO images (image) VALUES('".mysqli_real_escape_string($link, file_get_contents($filename))."')"

Answer 2

使用file_put_contents

file_put_contents($imgBlob, file_get_contents($url));
