Splitting an array into the variables in php
提问by sujitrulz
I have this array, $display_vars, and I want to split it into separate variables, so each variable's name is the array key, and it's value is the value, so to speak. So if the array was like this:
我有这个数组 $display_vars，我想把它拆分成单独的变量，所以每个变量的名称是数组键，它的值是值，可以这么说。所以如果数组是这样的：
$display_vars = array(
'title' => 'something',
'header' => 'something else'
);
Then I want to end up with the equivalent of this:
然后我想以这样的方式结束：
$title = 'something';
$header = 'something else';
Can you think of any way I can possibly do this?
你能想出我有什么办法可以做到这一点吗？

The extractfunction does exactly this.
该extract函数正是这样做的。
See it in action(includes bonus reference to get_defined_vars).
看到它在行动（包括奖金参考get_defined_vars）。

Why don't you use just access it using the same array ? Calling a function like extractis just an overload.
为什么不使用仅使用相同的数组访问它？调用像这样的函数extract只是一个重载。
<?php
$display_vars = array(
'title' => 'something',
'header' => 'something else'
);
echo $display_vars['title']; //something
echo $display_vars['header']; //something else
