将 PHP 数组字符串转换为数组 [英] Convert PHP array string into an array

问题描述

我有一个数组:

$myArray = array('key1'=>'value1', 'key2'=>'value2');

我将其保存为变量:

$fileContents = var_dump($myArray);

如何将变量转换回用作常规数组?

How can convert the variable back to use as a regular array?

echo $fileContents[0]; //output: value1
echo $fileContents[1]; //output: value2

推荐答案

我想你可能想看看 serialize 和 反序列化.

I think you might want to look into serialize and unserialize.

$myArray = array('key1'=>'value1', 'key2'=>'value2');
$serialized = serialize($myArray);
$myNewArray = unserialize($serialized);
print_r($myNewArray); // Array ( [key1] => value1 [key2] => value2 )
