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...';

Answer 2

$x+=10;

Is this what you're wanting?

Answer 3

it's pretty simple. $x += 10; is same as $x = $x + 10;

Answer 4

Like in many other languages:

$x += 10;

Answer 5

$x +=10; is equivalent to $x = $x +10;

Answer 6

$x += 10; adds 10 to $x

or

$x += $x; adds $x to itself, but you could just do: $x *= 2;
