使用apache ab工具进行测试了下。
ab -n100 -c10 https://you domain/
方法1：原生php函数
$str = 'my_name_is_bill';
echo implode('', array_map(function($val) {
return ucfirst($val);
}, explode('_', $str)));
测试结果

方法2: 自己编写php代码
$str = 'my';
if ( strpos($str, '_') === false ) {
echo ucfirst($str);exit;
}
$return = '';
foreach ( explode('_', $str) as $val ) {
$return .= ucfirst($val);
}
echo $return;
