Before I get harassed, yes, I DID use Google. Still no help.

Can somebody explain wtf the ".=" operator does in php? I did find:

x.=y is the same as x=x.y

so does that mean if x = "hello " and y = "world" then

x.=y

will make "hello world"?

just a little confused. i don't know if this is worthy of a topic but i was really on my last nerve. thanks

It's a string append operator. If you know javascript, its the same as '+='

$x = "abc";
$y = "def";
$x .= $y

// $x now equals "abcdef"

Your example ("hello world") is correct.
