我怎么能摘取MySQL储存的雕像的序列值? 数值看上去:a:{s1:/...>}。 这是什么?

最佳回答

PHP有serialize(。 职能将任何变数都变成如此之大。

echo serialize(array( foo , 3, array( bar  =>  BAR )));
// a:3:{i:0;s:3:"foo";i:1;i:3;i:2;a:1:{s:3:"bar";s:3:"BAR";}}

返回原物体:unserialize(

问题回答

PHP:Serialization——将PHP系列产出转换为等效的简单灵活手段 永久记忆结构,反之亦然。

use PHP::Serialization qw(serialize unserialize);
my $encoded = serialize({ a => 1, b => 2});
my $hashref = unserialize($encoded);
