问题描述
如何在PHP中解析var_dump
的输出以创建数组?
How can I parse the output of var_dump
in PHP to create an array?
推荐答案
如果需要表示形式,请使用 var_export 也是有效的PHP代码
Use var_export if you want a representation which is also valid PHP code
$a = array (1, 2, array ("a", "b", "c"));
$dump=var_export($a, true);
echo $dump;
将显示
array (
0 => 1,
1 => 2,
2 =>
array (
0 => 'a',
1 => 'b',
2 => 'c',
),
)
要将其转换为数组,您可以使用eval,例如
To turn that back into an array, you can use eval, e.g.
eval("\$foo=$dump;");
var_dump($foo);
不确定为什么,但是您想这样做.如果要在某个地方存储PHP数据结构,然后在以后重新创建它,请查看 serialize()和 unserialize(),它更适合此任务.
Not sure why you would want to do this though. If you want to store a PHP data structure somewhere and then recreate it later, check out serialize() and unserialize() which are more suited to this task.
