preg_match特殊字符

Question

I’m trying to make a preg_match in my PHP code, but I can't seem to get it to work.

I have these 3 tags

{$success url='http://www.domain.localhost/form-success'}
{$error url='http://www.domain.localhost/form-error'}
{$button title='send form'}

How can I get my preg_match to accept what I’m trying to do?

I’m trying to get {$button(*)} out to my match path, and the same I want to do with the 2 others {$success(*)} and {$error(*)}

Now I think it should look like this

preg_match("/\{\$button(.+?)}/s", $content, $match);

But it still isn’t working, so I hope other people can help me here.

Answer 1

\$ already means "literal $" in PHP strings, so when put in a regex it just means "end of string".

Try \\\$ instead.
