$state = array("gujarat","andhra_pradesh","madhya_pradesh","uttar_pradesh");

预期产出

$state = array("Gujarat","Andhra Pradesh","Madhya Pradesh","Uttar Pradesh");

我想使用UpperCase将单词的每个第一个字符转换为数组值,并将_替换为空格.所以我使用这个循环并按预期工作.

foreach($states as &$state)
 {
    $state = str_replace("_"," ",$state);
    $state = ucwords($state);
 }

但我的问题是：是否有任何PHP函数可以根据我的要求转换整个数组？
