ReflectionProperty::getDocComment — Gets the property doc comment
此函数没有参数。
The doc comment if it exists, otherwise false.
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
