范例

Example #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());

?>

以上例程的输出类似于：

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

Example #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;
}
?>

以上例程会输出：

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