Example #1 ReflectionParameter::getType() example
<?php
function someFunction ( int $param , $param2 ) {}
$reflectionFunc = new ReflectionFunction ( 'someFunction' );
$reflectionParams = $reflectionFunc -> getParameters ();
$reflectionType1 = $reflectionParams [ 0 ]-> getType ();
$reflectionType2 = $reflectionParams [ 1 ]-> getType ();
echo $reflectionType1 ;
var_dump ( $reflectionType2 );
