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 8.5.

Example:

Check if string is serialized:

$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

Check first if data is not serialized then serialize it:

$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";}}

Check first if data is not unserialized then unserialize it:

$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)

Working with JSON:

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

Working with base64:

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
