php操作csv文件代码实例汇总

1.读取csv数据, 输出到sales.csv文件中：

    $sales = array(
      array('Northeast', '2004-01-01', '2004-02-01', 12.54),
      array('Northwest', '2004-01-01', '2004-02-01', 546.33),
      array('Southeast', '2004-01-01', '2004-02-01', 93.26),
      array('Southwest', '2004-01-01', '2004-02-01', 945.21),
      array('All Regions', '---', '--', 1597.34),
    );

    $fh = fopen('sales.csv', 'w') or die("Can't open sales.csv");
    foreach($sales as $sales_line){
      if(fputcsv($fh, $sales_line) === false){
        die("Can't write CSV line");  
      }
    }

    fclose($fh) or die("Can't close sales.csv");

2. 读取csv数据, 使用特殊的流输出

    $sales = array(
      array('Northeast', '2004-01-01', '2004-02-01', 12.54),
      array('Northwest', '2004-01-01', '2004-02-01', 546.33),
      array('Southeast', '2004-01-01', '2004-02-01', 93.26),
      array('Southwest', '2004-01-01', '2004-02-01', 945.21),
      array('All Regions', '---', '--', 1597.34),
    );

    $fh = fopen('php://output', 'w');
    foreach($sales as $sales_line){
      if(fputcsv($fh, $sales_line) === false){
        die("Can't write CSV line");  
      }
    }

    fclose($fh);

3. 读取csv数据, 输出到缓冲中

    $sales = array(
      array('Northeast', '2004-01-01', '2004-02-01', 12.54),
      array('Northwest', '2004-01-01', '2004-02-01', 546.33),
      array('Southeast', '2004-01-01', '2004-02-01', 93.26),
      array('Southwest', '2004-01-01', '2004-02-01', 945.21),
      array('All Regions', '---', '--', 1597.34),
    );

    ob_start();
    $fh = fopen('php://output', 'w') or die("Can't open php://output");
    foreach($sales as $sales_line){
      if(fputcsv($fh, $sales_line) === false){
        die("Can't write CSV line");  
      }
    }

    fclose($fh) or die("Can't close php://output");
    $output = ob_get_contents();
    ob_end_clean();

4. 读取csv文件的数据

    $fp = fopen('sample3.csv', 'r') or die("can't open file");
    print "<table>\n";
    while($csv_line = fgetcsv($fp)){
      print '<tr>';
      for($i=0, $j=count($csv_line); $i<$j; $i++){
        // print '<td>'.htmlentities($csv_line[$i]).'</td>';  
        print '<td>'.htmlentities(iconv("gb2312","utf-8",$csv_line[$i])).'</td>';
      }
      print "</tr>\n";
    }
    print "</table>\n";
    fclose($fp) or die("can't close file");

5. 下载CSV文件

    $sales = array(
      array('Northeast', '2004-01-01', '2004-02-01', 12.54),
      array('Northwest', '2004-01-01', '2004-02-01', 546.33),
      array('Southeast', '2004-01-01', '2004-02-01', 93.26),
      array('Southwest', '2004-01-01', '2004-02-01', 945.21),
      array('中国', '2004-01-01', '2004-02-01', 945.21),
    );

    $fh = fopen('php://output', 'w') or die("can't open php://output");
    $total = 0;

    // 告诉浏览器发送的是一个csv文件
    header('Content-Type: application/csv');
    header('Content-Disposition: attachment; filename="sales.csv"');

    // 输出表头
    fputcsv($output, array('Region', 'Start Date', 'End Date', 'Amount'));
    // 输出每一行数据, 并递增$total
    foreach($sales as $sales_line){
      if(fputcsv($fh, $sales_line) === false){
        die("Can't write CSV line");  
      }else{
        $total += $sales_line[3];  
      }
    }

    fputcsv($fh, array('All Regions', '--', '--', $total));

    fclose($fh) or die("Can't close php://output");

6.读取CSV文件指定行和区间行

    /*****读取CSV文件中的指定行*****/
    function get_file_line_a($file_name,$line){
     $n = 0;
     $handle = fopen($file_name,'r');
     if ($handle) {
      while (!feof($handle)) {
        ++$n;
        $out = fgets($handle, 4096);
        if($line==$n) break;
      }
      fclose($handle);
     }
     if( $line==$n) return $out;
     return false;
    }

    echo get_file_line("windows_2011_s.csv", 10);//输入第10行内容


    /*****读取CSV文件中的区间行*****/
    function get_file_line_b( $file_name,$line_star, $line_end){
      $n = 0;
      $handle = fopen($file_name,"r");
      if ($handle) {
        while (!feof($handle)) {
          ++$n;
          $out = fgets($handle, 4096);
          if($line_star <= $n){
            $ling[] = $out;
          }
          if ($line_end == $n) break;
        }
        fclose($handle);
      }
      if( $line_end==$n) return $ling;
      return false;
    }

    //用 get_file_line读取并输出第11行到第20行

    $aa = get_file_line("windows_2011_s.csv", 11, 20); //从第11行到第20行
    foreach ($aa as $bb){
      echo $bb."<br>";
    }
