ReflectionParameter::isArray — Checks if parameter expects an array
本函数已自 PHP 8.0.0 起被废弃。强烈建议不要依赖本函数。
See the example below for an alternative way to derive this information.
Checks if the parameter expects an array.
此函数没有参数。
true if an array is expected, false otherwise.
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));
}
?>
