Export MySQL data to Excel without tripartite class library

If you often export data, you may encounter using a third-party library to export the upper limit, which is a very helpless thing. When there are more than 20,000 pieces of data, the export often fails. It is easy to reach the upper limit of PHP memory usage

/ / output the Excel header and change the user.csv to the file name you want: header ('Content-Type: application/vnd.ms-excel'); header (' Content-Disposition: attachment;filename= "user.csv"); header ('Cache-Control: max-age=0'); / / get the data from the database. In order to save memory, do not read the data into memory at once. Read one line from the handle to $sql =' select * from tbl where.' ; $stmt = $db- > query ($sql); / / Open the PHP file handle, and php://output means output directly to the browser $fp = fopen ('php://output', 'a'); / / output Excel listing information $head = array ('name', 'gender', 'age', 'Email',' phone','.') ; foreach ($head as $I = > $v) {/ / CSV's Excel supports GBK encoding, be sure to convert, otherwise garbled $head [$I] = iconv ('utf-8',' gbk', $v);} / / write data to the file handle fputcsv ($fp, $head) via fputcsv; / / counter $cnt = 0; / / refresh the output buffer, not too big or too small, $limit = 100000 / / fetch data line by line without wasting memory while ($row = $stmt- > fetch (Zend_Db::FETCH_NUM)) {$cnt + +; if ($limit = = $cnt) {/ / refresh the output buffer to prevent problems caused by too much data ob_flush (); flush (); $cnt = 0;} foreach ($row as $I = > $v) {$row [$] = iconv ('utf-8',' gbk', $v) } fputcsv ($fp, $row);}

The method here is to use fputcsv to write CSV files and output Excel files directly to the browser.
