将数组转换为UTF-8? PHP JSON

时间:2021-05-21 20:12:50

i have multidimensional arrays generated by PHP with data from database ,but i have chars like "č ć š đ ž" and when i try to output that in json he just returns null , i did some reading about that ,and it says that JSON is only working with UTF-8. So how can i convert those arrays in UTF-8 ? but i still need arrays at the and?

我有PHP生成的多维数组与来自数据库的数据,但我有像“čćšđž”的字符,当我尝试在json中输出它只是返回null,我做了一些关于它的阅读,它说JSON仅适用于UTF-8。那么如何在UTF-8中转换这些数组呢?但是我仍然需要数组和?

here is code of my script

I've found iconv to be the best method of converting a character set to UTF-8. You can make use of PHP's array_walk_recursive to work with multidimensional arrays:

我发现iconv是将字符集转换为UTF-8的最佳方法。您可以使用PHP的array_walk_recursive来处理多维数组:

$array = array(); // This is your multidimensional array

array_walk_recursive($array, function(&$value, $key) {
    if (is_string($value)) {
        $value = iconv('windows-1252', 'utf-8', $value);
    }
});

You can change windows-1252 to whichever character set you're converting from.

您可以将windows-1252更改为您要转换的任何字符集。

Try this function:

试试这个功能:

function utf8_converter($array)
{
    array_walk_recursive($array, function(&$item, $key){
        if(!mb_detect_encoding($item, 'utf-8', true)){
            $item = utf8_encode($item);
        }
    });

    return $array;
}

if multidimensional array, then use forearch loop and use this line inside foreach suppose

如果是多维数组,则使用forearch循环并在foreach中使用此行假设

forearch ($your_array as $line){
$line = array_map("utf8_decode", $line);    
}

that will convert your array to utf8... Enjoy.....

这将把你的数组转换为utf8 ...享受.....

Try this PHP function where you simply pass in the array you wish encoded.

尝试这个PHP函数,您只需传入您希望编码的数组。

function convertArrayKeysToUtf8(array $array) { 
$convertedArray = array(); 
foreach($array as $key => $value) { 
  if(!mb_check_encoding($key, 'UTF-8')) $key = utf8_encode($key); 
  if(is_array($value)) $value = $this->convertArrayKeysToUtf8($value); 

  $convertedArray[$key] = $value; 
} 
return $convertedArray; 
  } 

P.s check out php.net for other utf-8 encoding method ideas, but this has worked for me in the past.

I met this problem as well and in 2016 you don't need to create a function, just use 'mb_convert_variables'

我也遇到了这个问题,在2016年你不需要创建一个函数,只需使用'mb_convert_variables'

mb_convert_variables('UTF-8', 'original encode', array or object)

mb_convert_variables('UTF-8','原始编码',数组或对象)

For anyone who meet this situation, too.

对于任何遇到这种情况的人也是如此。
