如何使用PHP更改图像标记中的特定属性

Question

I am trying to change image attribute from data-original="" to src=""

Checkout the codes below

<img class="lazyjs bbcodeImage" src="//somesite.com/images/sample.gif" data-original="//somesite.com/images/sample.gif" alt="image">

in the above code we have 2 attributes 1st src="" and 2nd is data-original="" so i want to replace data-original="" to src="", I have tried using str_replace but it doesn't work,

$thumb = str_replace(array('data-original=','src='),array('src=','data='),$thumb);

how can i do this using PHP?

I assume that you have it in a string because you are trying to use PHP.

Here's what you need to do:

$content = '<img class="lazyjs bbcodeImage" src="//somesite.com/images/sample.gif" data-original="//somesite.com/images/sample.gif" alt="image">';
$content = preg_replace('/src="(.+?)"/','',$content); // Removes the old src
$content = str_replace('data-original','src',$content); // Renames data-original to src
