Example #1 Basic ReflectionClass::getReflectionConstants() example
<?php
class Foo {
public const FOO = 1;
protected const BAR = 2;
private const BAZ = 3;
}
$foo = new Foo();
$reflect = new ReflectionClass($foo);
$consts = $reflect->getReflectionConstants();
foreach ($consts as $const) {
print $const->getName() . "\n";
}
var_dump($consts);
?>
以上例程的输出类似于：
FOO
BAR
BAZ
array(3) {
[0]=>
object(ReflectionClassConstant)#3 (2) {
["name"]=>
string(3) "FOO"
["class"]=>
string(3) "Foo"
}
[1]=>
object(ReflectionClassConstant)#4 (2) {
["name"]=>
string(3) "BAR"
["class"]=>
string(3) "Foo"
}
[2]=>
object(ReflectionClassConstant)#5 (2) {
["name"]=>
string(3) "BAZ"
["class"]=>
string(3) "Foo"
}
}
