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         


        

Answer 1

$x += 10;

However some people find this harder to read.

What you tried ($x.= 10) works only for strings.

E.g.

$x = 'test';
$x.= 'ing...';
