HomeBackend DevelopmentPHP Tutorialphp数组中包含中文的排序方法_php实例

php数组中文排序,文件格式一般用utf8,直接用asort排序不行。若是gbk和gb2312可以。这跟编码有关。gbk和gb2312本身的编码就是用拼音排序的。

复制代码 代码如下:

function utf8_array_asort(&$array) {
if(!isset($array) || !is_array($array)) {
  return false;
}
foreach($array as $k=>$v) {
  $array[$k] = iconv('UTF-8', 'GB2312',$v);
}
asort($array);
foreach($array as $k=>$v) {
  $array[$k] = iconv('GB2312', 'UTF-8', $v);
}
return true;
}

使用例子:
复制代码 代码如下:

$abc = array('a'=>'猜', 'b'=>'我','c'=>'哦','d'=>'棍','e'=>'f','f'=>'爸','z'=>'州');
utf8_array_asort($abc);
print_r($abc);

但是使用这个函数发现,有些文字会出错,可能是utf8编码认不出某些字导致的“非法字符”,据了解GBK字符集比较大,换成GBK,再加上IGNORE忽略掉不认识的字符 ,改成下面这样
复制代码 代码如下:

private function utf8_array_asort(&$array) {
  if(!isset($array) || !is_array($array)) {
   return false;
  }
  foreach($array as $k=>$v) {
   $array[$k] = iconv('UTF-8', 'GBK//IGNORE',$v);
  }
  asort($array);
  foreach($array as $k=>$v) {
   $array[$k] = iconv('GBK', 'UTF-8//IGNORE', $v);
  }
  return true;
}
