Copy code The code is as follows:

/**
* Export data to CSV file
* @param array $data Data
* @param array $title_arr Title
* @param string $file_name CSV file name
*/
function export_csv(&$data, $title_arr, $file_name = '') {
ini_set("max_execution_time", "3600");

$csv_data = '';

/**title*/
$nums = count($title_arr);
for ($i = 0; $i < $nums - 1; ++$i) {
        $csv_data .= '"' . $title_arr[$i] . '",';
}

if ($nums > 0) {
$csv_data .= '"' . $title_arr[$nums - 1] . ""rn";
}

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] . ""rn";
        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")) { // Solve the bug of IE browser outputting garbled Chinese names

$file_name = urlencode($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;
}




2. Save to file

Copy code

The code is as follows:function export_csv($data, $title_arr, $file_name = '') {

$csv_data = '';

/**title*/
$nums = count($title_arr);

for ($i = 0; $i < $nums - 1; ++$i) {

$csv_data .= '"' . $title_arr[$i] . '",';
}


if ($nums > 0) {
$csv_data .= '"' . $title_arr[$nums - 1] . ""rn";

}

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] . ""rn";
                                                                                                                                                                                                                                             $csv_data.

$file_name = empty($file_name) ? date('Y-m-d-H-i-s', time()) : $file_name;
file_put_contents($file_name, $csv_data) ;
}

Call example
(save to file):

Copy code The code is as follows:

$file_name="/var/www/tmp/test.csv" ;
