ReflectionProperty::getDocComment

(PHP 5 >= 5.1.0, PHP 7, PHP 8)

ReflectionProperty::getDocComment — Gets the property doc comment

说明

public ReflectionProperty::getDocComment(): string|false

Gets the doc comment for a property.

参数

此函数没有参数。

返回值

The doc comment if it exists, otherwise false.

示例

示例 #1 ReflectionProperty::getDocComment() example

<?php
class Str
{
/**
* @var int The length of the string
*/
public $length = 5;
}

$prop = new ReflectionProperty('Str', 'length');

var_dump($prop->getDocComment());

?>

以上示例的输出类似于：

string(53) "/**
     * @var int  The length of the string
     */"

示例 #2 Multiple property declarations

If multiple property declarations are preceeded by a single doc comment, the doc comment refers to the first property only.

<?php
class Foo
{
/** @var string */
public $a, $b;
}
$class = new \ReflectionClass('Foo');
foreach ($class->getProperties() as $property) {
echo $property->getName() . ': ' . var_export($property->getDocComment(), true) . PHP_EOL;
}
?>

以上示例会输出：

a: '/** @var string */'
b: false
