php - Better way to add number to itself?

Question

Is there a better/shorter way in PHP of doing

$x = $x + 10;

i.e.

something like

$x .= 10; // (but this doesn't add together)

I am sure i've seen a shorter way than doing $x = $x + 10;

Answer 1

Have a look at: http://php.net/manual/language.operators.assignment.php (in the code examples and comments)

You can use:

$x += 10;

for example.
