Deserialization can't print it's weird how to fix it.

Deserialization doesn't print well, it's weird.
$safe _faqs = ' A:4:{i:1;a:2:{s:8: "question"; S:37: "What is your favorite Web-building program?"; S:6: "Answer"; s:7: "Dedecms";} I:2;a:2:{s:8: "Question"; S:6: "1+11=?"; S:6: "Answer"; S:2: "12";} I:3;a:2:{s:8: "Question"; s:59: "Which sport in China is the most people to listen to sad, watching the pain?"; S:6: "Answer"; S:6: "Football";} I:4;a:2:{s:8: "Question"; s:29: ""; s:6: "Answer"; s:24: "Weaving dream Content Management System";}} ';

$safefaqs = unserialize ($safe _faqs);

Print_r ($safefaqs);

The key to solving this type of problem is knowing how serialization strings are composed

such as s:6: "Football";
s represents a string
6 indicates a length of 6 bytes
What's included in the double quotes is the content.
Because of the length indication, there is no ambiguity in the possible double quotes in the content

For this example, it is observed that football is two kanji and the length is 6, which means that this is serialized in the UTF-8 encoding environment.

You save the program as UTF-8 encoded, or $safe _faqs = iconv (' GBK ', ' utf-8 ', $safe _faqs);
Turn the code, all can be output normally
