（已解决）文件名C：\ xampp \ tmp \ php4632.tmp在上传数据中不可读取excel与codeigniter到mysql
在此之前，我使用其他函数上传excel数据Codeigniter到MySQL，但显示错误的文件path不可读，然后我用这个代码上传Excel数据
//setting excel reader error_reporting(E_ALL ^ E_NOTICE); error_reporting(0); require_once 'include/excel_reader.php'; $get_periode = $this->input->post("periode"); $data = new Spreadsheet_Excel_Reader($_FILES['userfile']['tmp_name']); $count = 0; //read excel foreach($data->dump(false,false,false,false) as $row){ $value = $this->ruas_jalan_model->get_by(array("NAMA_KOTA"=>$row["NAMA_KOTA"]),FALSE,FALSE,TRUE); $data2 = array( "ID_PERIODE" => $get_periode, "NAMA_KOTA" => $value["NAMA_KOTA"], "NO_RUAS1" => $value["NO_RUAS1"], "NO_RUAS2" => $value["NO_RUAS2"], "NO_RUAS3" => $value["NO_RUAS3"], "NAMA_RUAS" => $value["NAMA_RUAS"], "PANJANG" => $value["PANJANG"], "HOTMIX_BAIK" => $value["HOTMIX_BAIK"], "HOTMIX_SEDANG" => $value["HOTMIX_SEDANG"], "HOTMIX_RR" => $value["HOTMIX_RR"], "HOTMIX_RB" => $value["HOTMIX_RB"], "LAPEN_BAIK" => $value["LAPEN_BAIK"], "LAPEN_SEDANG" => $value["LAPEN_SEDANG"], "LAPEN_RR" => $value["LAPEN_RR"], "LAPEN_RB" => $value["LAPEN_RB"], "LPC" => $value["LPC"], "TANAH" => $value["TANAH"], "HUTAN" => $value["HUTAN"], "LANG" => $value["LATITUDE"], "LOT" => $value["LOTITUDE"] ); $this->ruas_jalan_model->save($data2); $count++; } 但我仍然得到错误不可读，我不知道为什么，这是错误代码
The filename C:\xampp\tmp\php4632.tmp is not readable
怎么了 ？
问题是库无法读取与扩展xlsx（ms.office 2007 – >）的excel，然后我使用xls（ms.office 2003）
