Replace underscore with space and upper case first character in array
提问by Sadikhasan
I have the following array.
我有以下数组。
$state = array("gujarat","andhra_pradesh","madhya_pradesh","uttar_pradesh");
Expected Output
预期产出
$state = array("Gujarat","Andhra Pradesh","Madhya Pradesh","Uttar Pradesh");
I want to convert array values with each first character of a word with UpperCaseand replace _with space. So I do it using this loop and it working as expected.
我想数组值转换成一个字的每个第一个字符UpperCase和替换_用space。所以我使用这个循环来做它并且它按预期工作。
foreach($states as &$state)
{
$state = str_replace("_"," ",$state);
$state = ucwords($state);
}
But my question is: is there any PHP function to convert the whole array as per my requirement?
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？

You can use the array_mapfunction.

function modify($str) {
return ucwords(str_replace("_", " ", $str));

然后只需使用上述功能，如下所示：
$states=array_map("modify", $old_states)

Need to use array_mapfunction like as
需要使用array_map像 as
$state = array("gujarat","andhra_pradesh","madhya_pradesh","uttar_pradesh");
$state = array_map(upper, $state);
function upper($state){
return str_replace('_', ' ', ucwords($state));
}
print_r($state);// output Array ( [0] => Gujarat [1] => Andhra pradesh [2] => Madhya pradesh [3] => Uttar pradesh )

PHP's array_mapcan apply a callback method to each element of an array:
PHP 的 array_map可以对数组的每个元素应用回调方法：
$state = array_map('makePretty', $state);
function makePretty($value)
{
$value= str_replace("_"," ",$value);
return ucwords($value);
}

Use array_map()function
使用array_map()功能
<?php
function fun($s)
{
$val = str_replace("_"," ",$s);
return ucwords($val);
}
$state = array("gujarat","andhra_pradesh","madhya_pradesh","uttar_pradesh");
$result = array_map('fun',$state);
print_r($result);
?>
