(PHP 4, PHP 5)
get_class_methods — 返回由类的方法名组成的数组
返回由 class_name
指定的类中定义的方法名所组成的数组。如果出错,则返回 NULL
。
Note:
从 PHP 4.0.6 开始,可以指定对象本身来代替
class_name
,例如:<?php
$class_methods = get_class_methods($my_object); // see below the full example
?>
Example #1 get_class_methods() 示例
<?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\n";
}
?>
以上例程会输出:
myclass myfunc1 myfunc2
自 PHP 5 起,本函数按照方法被定义的名字返回(区分大小写)。在 PHP 4 中总是返回小写的。
class_name
The class name or an object instance
Returns an array of method names defined for the class specified by
class_name
. In case of an error, it returns NULL
.
版本 | 说明 |
---|---|
5.0.0 | As of PHP 5, this function returns the name of the methods as they were declared (case-sensitive). In PHP 4 they were lowercased. |
4.0.6 | The ability of specifying the object itself has been added. |
Example #2 get_class_methods() example
<?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\n";
}
?>
以上例程会输出:
myclass myfunc1 myfunc2
