使用src属性作为href将img标记包装在标记中

Question

I need help turning something like:

<img class="coup-pic" src="http://example.com/img/pic.jg" alt="" />

into:

<a href="http://example.com/img/pic.jg"><img class="coup-pic" src="http://example.com/img/pic.jg" alt="" /></a>

I need to be able to dynamically search for a string like the one above using PHP and wrap it in an a tag with the src attribute used as the a tag. I think I'll need to use preg_replace, but I do not know the right regex to use.

Thanks for the help!

Answer 1

I'm not currently somewhere where I can test this, but give this a try:

$html = preg_replace('/(<img [^>]*src="([^"]*)"[^>]*>)/i', '<a href="$2">$1</a>', $html);
