Better way to add number to itself?

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 tha开发者_JS百科n doing $x = $x + 10;

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.

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

---

$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...';

---

Like in many other languages:

$x += 10;

More information: Assignment Operators

---

$x+=10;

Is this what you're wanting?

---

$x += 10; adds 10 to $x

or

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

---

You are looking for this:

$x += 10;

---

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

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