The Serializer classes provide functional with serialization such as check if string is serialized, maybe serialize, maybe unserialize, or is JSON encoded (valid JSON) for prevent double serialization. This Serializer also supported unicode text.
Tested up to PHP 8.4.
$Serializer = new \Rundiz\Serializer\Serializer();
$serialized_string = 's:54:"this is a string. สตริงภาษาไทย";';
$faked_serialized_string = 's:12:"fake serialized string";';
var_dump($Serializer->isSerialized($serialized_string);// true
var_dump($Serializer->isSerialized($faked_serialized_string);// false
Or you can use static methods from \Rundiz\Serializer\SerializerStatic
class with the same method as \Rundiz\Serializer\Serializer
class.
$serialized_string = 's:54:"this is a string. สตริงภาษาไทย";';
var_dump(\Rundiz\Serializer\SerializerStatic::isSerialized($serialized_string));// true
$raw_data = array('mango', 'tree' => array('mango', 'banana'));
echo $Serializer->maybeSerialize($raw_data);// a:2:{i:0;s:5:"mango";s:4:"tree";a:2:{i:0;s:5:"mango";i:1;s:6:"banana";}}
echo \Rundiz\Serializer\SerializerStatic::maybeSerialize($raw_data);// a:2:{i:0;s:5:"mango";s:4:"tree";a:2:{i:0;s:5:"mango";i:1;s:6:"banana";}}
$serialized_data = 'i:-5436;';
echo $Serializer->maybeUnserialize($serialized_data);// -5436 (integer)
echo \Rundiz\Serializer\SerializerStatic::maybeUnserialize($serialized_data);// -5436 (integer)
echo \Rundiz\Serializer\SerializerStatic::maybeUnserialize(-5436);// -5436 (integer)
var_dump($Serializer->isJSONEncoded('"Hello world"'));// true
var_dump($Serializer->isJSONEncoded('012345'));// false
var_dump($Serializer->isJSONEncoded('true'));// true
var_dump($Serializer->isJSONEncoded('false'));// true
var_dump($Serializer->isJSONEncoded('null'));// true
var_dump($Serializer->isJSONEncoded(true));// true
var_dump($Serializer->isJSONEncoded(false));// false
var_dump($Serializer->isJSONEncoded(null));// false
var_dump($Serializer->isBase64Encoded(5555));// false
var_dump($Serializer->isBase64Encoded('NTU1NQ=='));// true
var_dump($Serializer->isBase64Encoded('test'));// false
var_dump($Serializer->isBase64Encoded('dGVzdA=='));// true
var_dump($Serializer->isBase64Encoded(null));// false
