Warning: Wrong parameter count for ucwords() in E:\wwwroot\webtest\test.php on line 25

------解决方案--------------------
PHP code

$arr2    = explode('_', $s2);
function self_ucwords(&$p_a, $p_b)//通常传入2参数,也可以3个参数,更详细用法查手册
{
    $p_a    = ucwords($p_a);//一个参数
}
array_walk($arr2, 'self_ucwords');
echo    implode('', $arr2);
