Problem with fgetcsv function reading Chinese strings from csv files

Read csv file data function:

function getData($file) {
 $arr = array();
 if(($handle = fopen($file,"r")) !== FALSE) {
 while(($data = fgetcsv($handle)) !== FALSE) {

 $tmp = array();
 foreach($data as $key=>$v) {
 $tmp[] = mb_convert_encoding($v,"UTF -8","gbk"); /*Convert gbk code to utf-8, otherwise garbled characters will appear*/
 }

 $arr[] = $tmp;
 }
 }

 return $arr;
 }

Found that the Chinese string read is empty....

Solution: Replace the fgetcsv function with the custom _fgetcsv function

 function _fgetcsv(&$handle, $length = null, $d = ',', $e = '"') {
 $d = preg_quote($d);
 $e = preg_quote($ e);
 $_line = "";
 $eof=false;
 while ($eof != true) {
 $_line .= (empty ($length) ? fgets($handle) : fgets($handle, $ length));
 $itemcnt = preg_match_all('/' . $e . '/', $_line, $dummy);
 if ($itemcnt % 2 == 0)
 $eof = true;
 }
 $_csv_line = preg_replace('/(?: |[ ])?$/', $d, trim($_line));
 $_csv_pattern = '/(' . $e . '[^' . $e . ']* (?:' . $e . $e . '[^' . $e . ']*)*' . $e . '|[^' . $d . ']*)' . $d . '/' ; _ Preg_Match_all ($ _ csv_pattern, $ _CSV_LINE, $ _CSV_Matches);
 $ _csv_data = $ _CSV_Matches [1]; nt ($ _ csv_data); $ _csv_i ++) {
 $ _csv_data [ $_csv_i] = preg_replace('/^' . $e . '(.*)' . $e . '$/s', '$1' , $_csv_data[$_csv_i]);
 $_csv_data[$_csv_i] = str_replace($e . $e, $e, $_csv_data[$_csv_i]);
 }
 return empty ($_line) ? false : $_csv_data;
 }
