php查询类的方法总结

get_class_methods($class_name)

<?php
 
class myclass {
    // constructor
    function myclass()
    {
        return(true);
    }
 
    // method 1
    function myfunc1()
    {
        return(true);
    }
 
    // method 2
    function myfunc2()
    {
        return(true);
    }
}
 
$class_methods = get_class_methods('myclass');
// or
$class_methods = get_class_methods(new myclass());
 
foreach ($class_methods as $method_name) {
    echo "$method_name<br>";
}
 
?>

<?php
