print select serial unserialize

PHP的unserialize返回false

问题描述:如下是我序列化数组之后的数据,但是取出来之后,反序列化不了。
$a = 'a:2:{i:1;a:5:{s:8:"pic_sort";i:2;s:9:"pic_check";b:1;s:10:"pic_select";i:56;s:8:"pic_path";s:1:"ergregerg";s:8:"pic_link";s:2:"wesaddasd";}i:2;a:5:{s:8:"pic_sort";i:2;s:9:"pic_check";b:0;s:10:"pic_select";i:57;s:8:"pic_path";s:10:"4444";s:8:"pic_link";s:14:"http://fafa.com";}}';
print_r(unserialize($a));

问题原因:应该是从数据库中取出的编码和页面的编码不一致造成的。

解决方案:自定义如下的函数调用就可以了
???print_r(mb_unserialize($a));
???function mb_unserialize($serial_str) {?
?????$out = preg_replace('!s:(\d+):"(.*?)";!se', "'s:'.strlen('$2').':\"$2\";'", $serial_str );?
?????return unserialize($out);?
???}?
