Question

I’m using this simple code:

$raw = 'text [e-mail] text';
$raw = preg_replace('<[\w.]+@[\w.]+>', '***@$2', $raw);

And i should get as output, something like ***@li.com; while i get ***@

I can’t debug it, i don’t know how what’s wrong.

---

So the solution is

preg_replace('<([\w.]+)@([\w.]+)>', '***@$2', $raw);

I had to add () to make a group.

Answer 1

you need to create a group by adding (), and BTW it’s gonna be $1:

$raw = ' [e-mail] ';
$raw = preg_replace('/[^@]+@([^\s]+)/', '***@$1', $raw);

also modified .+ tp [^\s]+ so it “eats” only the email and not the text after it
