Phpunserialize function error, strange?

{Code...} This is code, a simple string, but an error still occurs...

$test_str = "code|s:5:\"ZH9JC\";state|s:10:\"wn4rzbnxpp\";";var_dump(unserialize($test_str));

This is the code, a simple string, but still an error...

Is the serialized $ test_str an array? Obviously not after serialize. If yes, serialization does not look like this, as shown below:

$arr = array(            'code' => 'ZH9JC',            'state' => 'wn4rzbnxpp'        );$str = serialize($arr);dump($str);// string(59) "a:2:{s:4:"code";s:5:"ZH9JC";s:5:"state";s:10:"wn4rzbnxpp";}"$content = unserialize($str);dump($content);//array(2) {  ["code"] => string(5) "ZH9JC"  ["state"] => string(10) "wn4rzbnxpp"}

Your string is not a standard serialized value. if the unserialize function cannot identify your character change, it will be wrong.

$ Test_str are the results of serialize?

The format is not serialized...

It is not serialized, so it cannot be converted
