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.
