Better way to add number to itself?
提问by Lee
Is there a better/shorter way in PHP of doing
PHP 中是否有更好/更短的方法
$x = $x + 10;
i.e.
IE
something like
就像是
$x .= 10; // (but this doesn't add together)
I am sure i've seen a shorter way than doing $x = $x + 10;
我确定我见过比做更短的方法 $x = $x + 10;

$x += 10;
$x += 10;
However some people find this harder to read.
然而,有些人发现这更难阅读。
What you tried ($x.= 10
) works only for strings.
您尝试的 ( $x.= 10
) 仅适用于字符串。
E.g.
例如
$x = 'test';
$x.= 'ing...';

it's pretty simple. $x += 10; is same as $x = $x + 10;
这很简单。$x += 10; 与 $x = $x + 10 相同;
