替換PHP

Question

與HTML圖像標記數組值我這裏有一個數組如下：

<?php 
print_r($result); 
?> 

如果我要執行上面的代碼，它下面的結果：

Array 
(
[0] => Array 
    (
     [id] => 1 
     [uploaded_by] => 1 
     [image_url] => http://localhost/dir/img_2.jpg 
     [work_description] => test 
     [date_added] => 2017-08-03 02:12:38 
    ) 

[1] => Array 
    (
     [id] => 2 
     [uploaded_by] => 1 
     [image_url] => http://localhost/dir/img_4.jpg 
     [work_description] => test 
     [date_added] => 2017-08-03 02:13:04 
    ) 

[2] => Array 
    (
     [id] => 3 
     [uploaded_by] => 1 
     [image_url] => http://localhost/dir/img_2.jpg 
     [work_description] => test 
     [date_added] => 2017-08-03 02:46:28 
    ) 

[3] => Array 
    (
     [id] => 4 
     [uploaded_by] => 1 
     [image_url] => http://localhost/dir/img_2.jpg 
     [work_description] => sdfsdf 
     [date_added] => 2017-08-03 02:46:34 
    ) 
) 

現在，從$result陣列我想改變所有image_url 以編程方式使用PHP到HTML中的圖像。

例如：

http://localhost/dir/img_2.jpg將成爲如果我要執行的代碼

<img src="http://localhost/dir/img_2.jpg"/>

這些值必須改變。

有人知道嗎？

你可以把它放在一個foreach和修改只有你想要的部分：

foreach($result as $key => $value) { 
    $result[$key]['image_url'] = '<img src="'.$value['image_url'].'"/>'; 
} 

print_r($result);
