Hi, this is simple example of how to use it.
class Test
{
public function testArray(array $a)
{
// do something...
return $a;
}
public function testString(string $a)
{
// do something...
return $a;
}
}
$reflection = new ReflectionClass('Test');
foreach($reflection->getMethods() as $methods){
foreach($methods->getParameters() as $param){
var_dump($param->isArray());
}
}
//bool(true)
//bool(false)
ReflectionParameter::isArray
(PHP 5 >= 5.1.2, PHP 7, PHP 8)

Example #1 PHP 8.0.0 equivalent
As of PHP 8.0.0, the following code will report if a type declares arrays, including as part of a union.
<?php
function declaresArray(ReflectionParameter $reflectionParameter): bool
{
$reflectionType = $reflectionParameter->getType();
if (!$reflectionType) return false;
$types = $reflectionType instanceof ReflectionUnionType
? $reflectionType->getTypes()
: [$reflectionType];
return in_array('array', array_map(fn(ReflectionNamedType $t) => $t->getName(), $types));
}
?>
