在PHP中，有没有办法以编程方式调用对象的所有方法？
我有一个充满包含 HTML 片段的方法的对象：
class Example {
public function introduction(){
?>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>
<?php
}
public function step_one(){
?>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>
<?php
}
Etc...
}
有没有办法在循环中按顺序调用所有这些方法？还是我必须直呼他们的名字？
如果您不知道该类中将有多少个方法，但您知道每个方法的名称基础。然后，您可以像这样循环访问它们：
<?php
class Example {
public static function loop() {
self::introduction();
$name = "step_one";
$int = 2;
$formater = new NumberFormatter("en", NumberFormatter::SPELLOUT);
while (true) {
if (method_exists(get_class(), $name)) {
self::$name();
$number = $formater->format($int);
$name = "step_" . $number;
$int ++;
}
else {
break;
}
}
}
public static function introduction(){
?>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>
<?php
}
public static function step_one(){
?>
<p>1Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>
<?php
}
public static function step_two(){
?>
<p>2Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>
<?php
}
public static function step_three(){
?>
<p>3Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>
<?php
}
}
Example::loop();
?>
或者，您可以按声明顺序循环访问它们，如下所示：
<?php
class Example {
public function loop() {
$methods = get_class_methods(get_class());
foreach ($methods as $method) {
if ($method != "loop") {
$this->$method();
}
}
}
public function introduction(){
?>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>
<?php
}
public function step_one(){
?>
<p>1Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>
<?php
}
public function step_two(){
?>
<p>2Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>
<?php
}
public function step_three(){
?>
<p>3Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>
<?php
}
}
$a = new Example();
$a->loop();
?>
感谢 C.Liddell 为我指明了正确的方向。这是我最终在我的构造函数中所做的：
public function __construct(){
$methods = get_class_methods($this);
foreach($methods as $method) :
if($method === '__construct') :
continue;
endif;
$this->$method();
endforeach;
}
