PHP实现数据导入、CSV文件下载的例子

class csv
{
private $resource;

/**
* @param string $fileName 文件路径
* @param string $mode 文件访问类型：w：写入、r：只读
*/
public function __construct($fileName, $mode)
{
$this->resource = fopen($fileName, $mode);
}

public function __destruct()
{
fclose($this->resource);
}

/**
* 导入CSV www.111com.net
* @param array $data
* @return int
*/
public function export($data)
{
fputcsv($this->resource, $data);
}

/**
* 导出CSV
* @return array
*/
public function import()
{
$tmp = array();
while($data = fgetcsv($this->resource))
{
$tmp[] = $data;
}

return $tmp;
}
}

function exportUserTask()
{
//获取数据库数据
/*
* $result = array(
* array(value1,value2,value3,value4,value5,value6),
* array(value1,value2,value3,value4,value5,value6),
* );
*/

$handle = fopen('php://output', "w");
header('Content-Type: application/csv');
header('Content-Disposition: attachment; filename="test.csv"');

//表头 www.111com.net
fputcsv($handle, array('用户UID', '用户名', '进行中', '已完成', '已失败', '总计'));

foreach($result as $value)
{
fputcsv($handle, $value);
}

fclose($handle);
}
