图片来自getImage.php将不会显示在img src

Question

所以基本上如果我去getImage链接，数据库中的图像会显示，但如果我用它在.php文件，它将显示图像但会调整大小以适应卡，它不会显示和alt（这是头像）显示。

<center> 
<img src="getImage.php" class="w3-circle" style="position:absolute; bottom:-20%; left:35.5%; width:30%" alt="Avatar"> 
</center> 

那么对于getImage.php代码：

<?php 
session_start(); 
require './Database.php'; 

// do some validation here to ensure id is safe 

$sql = "SELECT register.FULLNAME, register.IMAGE, gameData.NBA_SCORE FROM register inner join gameData on register.ID = gameData.ID WHERE NBA_SCORE = (select max(NEW_SCORE) from gameData)"; 
$result = mysqli_query($con, $sql); 
$row = mysqli_fetch_assoc($result); 
echo "<img src='".$row['IMAGE']."'>"; 
?> 

任何问题我在做什么？

问题

HTML改掉得到像JPG或PNG一个有效的图像文件，但得到的PHP /文本文件与内容<img src="...">。

解决方案

您需要更改的PHP文件内容类型的图像和输出的图像文件的数据：

header("Content-Type: image/jpeg");//or image/png 
echo file_get_contents("$imagepath");//file path not url!!! 

代码

<?php 
    session_start(); 
    require './Database.php'; 

    header("Content-Type: image/jpeg");  

    // do some validation here to ensure id is safe 

    $sql = "SELECT register.FULLNAME, register.IMAGE, gameData.NBA_SCORE FROM register inner join gameData on register.ID = gameData.ID WHERE NBA_SCORE = (select max(NEW_SCORE) from gameData)"; 
    $result = mysqli_query($con, $sql); 
    $row = mysqli_fetch_assoc($result); 
    $path = $row['IMAGE'];//Maybe you need to change this if you only save an url in the database 
    echo file_get_contents($path); 

?>
