Question

I use strings with this characters: { and }
Example:

Logged in with IP-Adress {ipAdress}

Or other example:

Your username was {userName}

Now i need a regex to find any strings, i tried this:

preg_match_all('/^{(.+)}/', $string, $matches)

But this don’t find that…
Who can help me here?

Answer 1

preg_match_all('/\{(.+?)\}/', $string, $matches)

{s are special in regular expressions. You need to escape them.

Additionally, ^ anchors to the start of the line. Your pattern isn’t at the start of a line.

Finally, per your comment below, you have more than one such demarcated string per line, so you want to use the non-greedy version of the search .+?.
