将关联数组转换为由键命名的单个变量
我有以下格式的数组。我想将其转换为另一种格式，如下所示。
Array
(
[b2] => 2
[b3] => 8
[b4] => 2
[b5] => 4
)
是否可以将 key 转换为 PHP 变量并将其值自动分配给变量？是否可以？
$b2 = 2;
$b3 = 8;
$b4 = 2;
$b5 = 4;
I have array in following format. I want to convert it into another format like below.
Array
(
[b2] => 2
[b3] => 8
[b4] => 2
[b5] => 4
)
Is it possible key is converted into PHP variables and its value automatically assigned to variables? Is it possible?
$b2 = 2;
$b3 = 8;
$b4 = 2;
$b5 = 4;

看起来你想要 extract()
looks like you want extract()
您正在寻找 extract() 函数。您将要提取的数组传递到当前作用域中，仅此而已。请注意，使用此功能时应非常小心；为了安全起见，请传递
EXTR_SKIP作为第二个参数，以防止覆盖现有变量，毕竟您不会想要$_SESSION或$_SERVER之类的变量代码> 被包含恶意数据的数组限制...You're looking for the extract() function. You pass in the array you want to extract into the current scope, and that's it. Mind though that you should be very careful when you use this function; for safety, pass
EXTR_SKIPin as the second argument to prevent overwriting existing variables, after all you wouldn't want the likes of$_SESSIONor$_SERVERthrottled by an array with malicious data...
