Reference - What does this symbol mean in PHP?

I see this symbol in a lot of PHP code.

I can't figure out what it means or what it does..

Is it really an operator ?

Do you mean =>? If so, it's for initializing array keys (or indexes if you prefer). Like this:

$values = array(
    'foo' => 'bar'
);

This will initiazlie an array with a key named foo with a value of bar.
