如何在此代码中插入图片

Answer 1

你应该像这样使用它来为你的数组添加元素， live demo

<?php
    $fortressMapping = [
       1 => "<img src=\"<?php echo $image_url;?>\">,'JG Fortress'",
            .....
    ];

Answer 2

删除$fortressMapping

中的回音

<?php
$image_url = "http://example.com/image.png";
        $fortressMapping = [
            1 => '<img src="$image_url">','JG Fortress',
            3 => '<img src="$image_url">','HT Fortress',
            4 => '<img src="$image_url">','Ban Fortress',
            6 => '<img src="$image_url">','Ban Fortress',
    ];

    print_r($fortressMapping);

Answer 3

你不能在var赋值内回应：

$fortressMapping = [
            1 => "<img src='{$image_url}'>",'JG Fortress',
            3 => "<img src='{$image_url}'>",'HT Fortress',
            4 => "<img src='{$image_url}'>",'Ban Fortress',
            6 => "<img src='{$image_url}'>",'Ban Fortress',
    ];
