PHP 中的动态类方法调用

Just omit the braces:

$this->$methodName($arg1, $arg2, $arg3);

There is more than one way to do that:

$this->{$methodName}($arg1, $arg2, $arg3);
$this->$methodName($arg1, $arg2, $arg3);
call_user_func_array(array($this, $methodName), array($arg1, $arg2, $arg3));

You may even use the reflection api http://php.net/manual/en/class.reflection.php

You can also use call_user_func() and call_user_func_array()

If you're working within a class in PHP, then I would recommend using the overloaded __call function in PHP5. You can find the reference here.

Basically __call does for dynamic functions what __set and __get do for variables in OO PHP5.

In my case.

$response = $client->{$this->requestFunc}($this->requestMsg);

Using PHP SOAP.

You can store a method in a single variable using a closure:

class test{


function echo_this($text){
echo $text;
}


function get_method($method){
$object = $this;
return function() use($object, $method){
$args = func_get_args();
return call_user_func_array(array($object, $method), $args);
};
}
}


$test = new test();
$echo = $test->get_method('echo_this');
$echo('Hello');  //Output is "Hello"

EDIT: I've edited the code and now it's compatible with PHP 5.3. Another example here

Still valid after all these years! Make sure you trim $methodName if it is user defined content. I could not get $this->$methodName to work until I noticed it had a leading space.

You can use the Overloading in PHP: Overloading

class Test {


private $name;


public function __call($name, $arguments) {
echo 'Method Name:' . $name . ' Arguments:' . implode(',', $arguments);
//do a get
if (preg_match('/^get_(.+)/', $name, $matches)) {
$var_name = $matches[1];
return $this->$var_name ? $this->$var_name : $arguments[0];
}
//do a set
if (preg_match('/^set_(.+)/', $name, $matches)) {
$var_name = $matches[1];
$this->$var_name = $arguments[0];
}
}
}


$obj = new Test();
$obj->set_name('Any String'); //Echo:Method Name: set_name Arguments:Any String
echo $obj->get_name();//Echo:Method Name: get_name Arguments:
//return: Any String
