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.

Answer 2

Not a PHP guy, but $x += 10; maybe?

Answer 3

$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 4

Like in many other languages:

$x += 10;
