php code$s2 = make_by_id;echo convstring($s1);function convstring($string){ $array = explode('_', $string); array_walk($array, ucwords); return implode('', $array);}
---------------------------------------------
warning: wrong parameter count for ucwords() in e:\wwwroot\webtest\test.php on line 25
------解决方案--------------------
php code$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);
------解决方案--------------------
$array = explode('_', $string);
array_walk($array, ucwords);
$array前加多个$array=array();
