　　请点击后面地址下载：csv操作类
使用说明如下：

1.生成csv文件

复制代码 代码如下:
require ./include/csvdatafile.php;

set_time_limit(200);
header(Content-type: application/RFC822);
header(Content-Disposition: attachment; filename=export.csv);

$arr_export_titles = array(学生编号,学号,学生姓名);

$csvfile = new csvDataFile(, ,, w);
echo $csvfile->printline($arr_export_titles);
//方法一
$print_data1[] = 1;
$print_data1[] = 039413301;
$print_data1[] = 张三;
echo $csvfile->printline($print_data1);

$print_data2[] = 2;
$print_data2[] = 039413302;
$print_data2[] = 李四;
echo $csvfile->printline($print_data2);


$print_data3[] = 3;
$print_data3[] = 039413303;
$print_data3[] = 王五;
echo $csvfile->printline($print_data3);


//方法二
$print_data[1][] = 1;
$print_data[1][] = 039413301;
$print_data[1][] = 张三;
$print_data[2][] = 2;
$print_data[2][] = 039413302;
$print_data[2][] = 李四;
$print_data[3][] = 3;
$print_data[3][] = 039413303;
$print_data[3][] = 王五;
echo $csvfile->printcsv($print_data);





2.打开csv读数据



代码
复制代码 代码如下:
require ./include/csvdatafile.php;

$filename = E:/development/csvfile/datefile.csv;

// Read file source
$handle = fopen($filename, r);
$contents = fread($handle, filesize($filename));
fclose($handle);

// format content for special chars
$contents = @addslashes($contents);
$contents = @str_replace(\,, \ ,, $contents);
$contents = @stripslashes($contents);

// Write to new file
$handle = @fopen($filename, w);
@fwrite($handle, $contents);
@fclose($handle);

$fd = @fopen($filename, rb);
$first_line = str_replace( ,,,,str_replace(,,trim(@fgets($fd, 1000)))) ;
@fclose($fd);

if($first_line != 学生编号,学号,学生姓名) {
$pass = false;
}

if($pass){
$csv = new csvDataFile($filename);
while($csv->next_Row()) {
$userid = trim($csv->f(学生编号));
$classno = trim($csv->f(学号));
$username = trim($csv->f(学生姓名));
}
}
