codeigniter - PHP 参数不定,如何动态调用方法?
如:
我现在有三个方法
<code>foo($a,$b=null) boo($a=array(),$b="") Roo($a) </code>
现在我只需要传递方法名称和参数列表就能直接调用方法。
希望是可以这样(伪代码):
<code>function run_function($fun_name,$paras) { {$fun_name}(....//这里应该怎么写呢?); } </code>
自己找到正确答案了,谢谢下面两个回复的,但真不是我需要的答案。现贴出解决方案:
<code>$handler = array( 'test', 'test3'); $params = array( array(1,2,3,4), 1 ); if($params == null) { call_user_func($handler); } if (is_callable($handler) ) { call_user_func_array( $handler , $params ); } class test { function test1($arr,$arr1) { var_dump(array_merge($arr,$arr1)); } function test2() { echo 123; } function test3($arr,$a) { var_dump($arr); var_dump($a); } }</code>

http://www.php.net/manual/zh/function.func-get-args.php
<code>function run_function($fun_name) { if(function_exists($fun_name)) { $num = func_num_args(); $args = func_get_args(); array_shift($args); return $num==1 ? call_user_func($fun_name) : call_user_func_array($fun_name,$args); } trigger_error('Call to undefined function ' . $fun_name, E_USER_ERROR); } //使用 run_function('foo', $a, $b); run_function('boo', $a, $b); run_function('Roo', $a);</code>
