如何从对象获取getter？

Question

My SimpleClass:

class Simple
{
    private $test;

    public function other() {};
    public function getTest() {};
    public function setTest() {};
    public function getSecond() {};
    public function setSecond() {};
}

How to get from this class all getters?

$ref = new \ReflectionClass(new SimpleClass());
$allMethods = $ref->getMethods();

And how can I get from $allMethods only getters (getTest, getSecond)?

Answer 1

According to the manual, the getMethods method returns an array so simply looping across it should yield what you want.

The returned array is an array of reflectionMethod objects so you could even look at the visibility properties - i.e. ->isPublic()

<?PHP

class Simple
{
    private $test;

    public function other() {}
    public function getTest() {}
    public function setTest() {}
    public function getSecond() {}
    public function setSecond() {}
}

$ref = new \ReflectionClass(new SimpleClass());
$allMethods = $ref->getMethods();

$getters = array();
$publicGetters = array();

for ($methodNum=0; $methodNum < count($allMethods); $methodNum++)
{
        if( substr( $allMethods[$methodNum]->getName(), 0, 3 ) == 'get' )
        {
            $getters[] = $allMethods[$methodNum];
            if( $allMethods[$methodNum]->isPublic() )
            {
                $publicGetters[] = $allMethods[$methodNum];
            }
        }
}
