ReflectionParameter::isArray — Checks if parameter expects an array
本函數已自 PHP 8.0.0 起被廢棄。強烈建議不要依賴(lài)本函數。
See the example below for an alternative way to derive this information.
Checks if the parameter expects an array.
此函數沒(méi)有參數。
true if an array is expected, false otherwise.
示例 #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));
}
?>
