$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));

问题缘故原由：该当是从数据库中取出的编码和页面的编码不一致造成的。

unserializephpPHP的unserialize返回false CSS

办理方案：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);

}
