Shieldfy Sniffer is a small composer package to detect the input type , now support 4 types ( integer , string , json , serialize)

Installation

Through Composer

composer require shieldfy/sniffer

Usage & Examples

$type = (new \Shieldfy\Sniffer\Sniffer)->sniff('12.5'); //number

$type = (new \Shieldfy\Sniffer\Sniffer)->sniff('hello world'); //string

$type = (new \Shieldfy\Sniffer\Sniffer)->sniff(json_encode(['hello'=>1,'world'=>'!'])); //json

$type = (new \Shieldfy\Sniffer\Sniffer)->sniff(serialize(['hello'=>1,'world'=>'!'])); //serialize

//you can add more than value as array
$type = (new \Shieldfy\Sniffer\Sniffer)->sniff(['555','abc']);

//test against particular type
$result = (new \Shieldfy\Sniffer\Sniffer)->is('123456789','number'); //true

//you can register your own sniffer on the runtime
$type = (new \Shieldfy\Sniffer\Sniffer)->register('hello',function($input){
	if(strstr($input,'hello')) 
		return true;
	return false;
})->sniff('say hello world');

note about serialization

Serialize / Unserialize can be danger due to its ability to convert object and it can be used to preform object injection attack. So explicit sniffing not allowed in php version before php 7 thats because php7 offered new options to prevent object serialization see here
