如果不清楚什么是CSV文件,可看如下文章介绍 CSV格式的是什么文件?CSV是什么的缩写?
/**
* 导出数据到CSV文件
* @param array $data 数据
* @param array $title_arr 标题
* @param string $file_name CSV文件名
*/
function export_csv(&$data, $title_arr, $file_name = '') {
ini_set("max_execution_time", "3600"); $csv_data = ''; /** 标题 */
$nums = count($title_arr);
for ($i = 0; $i < $nums - 1; ++$i) {
$csv_data .= '"' . $title_arr[$i] . '",';
} if ($nums > 0) {
$csv_data .= '"' . $title_arr[$nums - 1] . ""
";
} foreach ($data as $k => $row) {
for ($i = 0; $i < $nums - 1; ++$i) {
$row[$i] = str_replace(""", """", $row[$i]);
$csv_data .= '"' . $row[$i] . '",';
}
$csv_data .= '"' . $row[$nums - 1] . ""
";
unset($data[$k]);
} $csv_data = mb_convert_encoding($csv_data, "cp936", "UTF-8"); $file_name = empty($file_name) ? date('Y-m-d-H-i-s', time()) : $file_name; if (strpos($_SERVER['HTTP_USER_AGENT'], "MSIE")) { // 解决IE浏览器输出中文名乱码的bug
$file_name = urlencode($file_name);
$file_name = str_replace('+', '%20', $file_name);
} $file_name = $file_name . '.csv';
header("Content-type:text/csv;");
header("Content-Disposition:attachment;filename=" . $file_name);
header('Cache-Control:must-revalidate,post-check=0,pre-check=0');
header('Expires:0');
header('Pragma:public');
echo $csv_data;
}
应用举例:
$header = array(
'0' => '参数ID',
'1' => '参数名称',
'2' => '统计次数',
'3' => '统计次数百分比',
'4' => '唯一用户数',
'5' => '唯一用户数百分比',
'6' => '人均次数'
); /** 列表项 */
foreach ($list as $key => $row){
$csvList[] = array(
'0' => $row['param_key'],
'1' => $row['param_name'],
'2' => $row['nums'],
'3' => $row['percent_nums'] . '%',
'4' => $row['total_users'],
'5' => $row['percent_total_users'] .'%',
'6' => $row['avg']
);
} /** 导出csv */
$title = str_replace(' ','-', $title);
export_csv($csvList, $header, $title);
