php匯出csv檔案：指定編碼匯出與csv檔案匯入與匯出類

/* * PHP code to export MySQL data to CSV * * Sends the result of a MySQL query as a CSV file for download * Easy to convert to UTF-8. */ /* * establish database connection */ $conn = mysql_connect('localhost', 'login', 'pass') or die(mysql_error()); mysql_select_db('database_name', $conn) or die(mysql_error($conn)); mysql_query("SET NAMES CP1252"); /* * execute sql query */ $query = sprintf('SELECT field1,field2 FROM table_name'); $result = mysql_query($query, $conn) or die(mysql_error($conn)); /* * send response headers to the browser * following headers instruct the browser to treat the data as a csv file called export.csv */ header('Content-Type: text/csv; charset=cp1252'); header('Content-Disposition: attachment;filename=output.csv'); /* * output header row (if atleast one row exists) */ $row = mysql_fetch_assoc($result); if ($row) { echocsv(array_keys($row)); } /* * output data rows (if atleast one row exists) */ 匯出csv檔案 while ($row) { echocsv($row); $row = mysql_fetch_assoc($result); } /* * echo the input array as csv data maintaining consistency with most CSV implementations * - uses double-quotes as enclosure when necessary * - uses double double-quotes to escape double-quotes * - uses CRLF as a line separator */ function echocsv($fields) { $separator = ''; foreach ($fields as $field) { if (preg_match('/\\r|\\n|,|"/', $field)) { $field = '"' . str_replace('"', '""', $field) . '"'; } echo $separator . $field; $separator = ','; } echo "\r\n"; } ?> 複製代碼 二、php匯入與匯出csv檔案的類 php實現csv檔案的匯入和匯出類。代碼： /** * CSV 檔案處理類 */ class Csv{ public $csv_array; //csv數組資料 public $csv_str; //csv檔案資料 public function __construct($param_arr, $column){ $this->csv_array = $param_arr; $this->path = $path; $this->column = $column; } /** * 匯出 * */ public function export(){ if(empty($this->csv_array) || empty($this->column)){ return false; } $param_arr = $this->csv_array; unset($this->csv_array); $export_str = implode(',',$param_arr['nav'])."n"; unset($param_arr['nav']); //組裝資料 foreach($param_arr as $k=>$v){ foreach($v as $k1=>$v1){ $export_str .= implode(',',$v1)."n"; } } //將$export_str匯出 header( "Cache-Control: public" ); header( "Pragma: public" ); header("Content-type:application/vnd.ms-excel"); header("Content-Disposition:attachment;filename=txxx.csv"); header('Content-Type:APPLICATION/OCTET-STREAM'); ob_start(); // $file_str= iconv("utf-8",'gbk',$export_str); ob_end_clean(); echo $export_str; } /** * 匯入 * */ public function import($path,$column = 3){ $flag = flase; $code = 0; $msg = '未處理'; $filesize = 1; //1MB $maxsize = $filesize * 1024 * 1024; $max_column = 1000; //檢測檔案是否存在 if($flag === flase){ if(!file_exists($path)){ $msg = '檔案不存在'; $flag = true; } } //檢測檔案格式 if($flag === flase){ $ext = preg_replace("/.*.([^.]+)/","$1",$path); if($ext != 'csv'){ $msg = '只能匯入CSV格式檔案'; $flag = true; } } //檢測檔案大小 if($flag === flase){ if(filesize($path)>$maxsize){ $msg = '匯入的檔案不得超過'.$maxsize.'B檔案'; $flag = true; } } //讀取檔案 if($flag == flase){ $row = 0; $handle = fopen($path,'r'); $dataArray = array(); while($data = fgetcsv($handle,$max_column,",")){ $num = count($data); if($num < $column){ $msg = '檔案不符合規格真實有：'.$num.'列資料'; $flag = true; break; } if($flag === flase){ for($i=0;$i<3;$i++){ if($row == 0){ break; } //組建資料 $dataArray[$row][$i] = $data[$i]; } } $row++; } } return $dataArray; } } $param_arr = array( 'nav'=>array('使用者名稱','密碼','郵箱'), array(0=>array('xiaohai1','123456','xiaohai1@jbxue.com'), 1=>array('xiaohai2','213456','xiaohai2@jbxue.com'), 2=>array('xiaohai3','123456','xiaohai3@jbxue.com') )); $column = 3; $csv = new Csv($param_arr, $column); //$csv->export(); $path = 'C:\Documents and Settings\Administrator\Temp\txxx.csv'; $import_arr = $csv->import($path,3); var_dump($import_arr); ?> 複製代碼
