Use phpciforce_download($filename, unzip data‑download .csv file to solve file name garbled and file content garbled

Use phpciforce_download($filename, $data‑download .csv file to solve file name garbled. use php CI force_download ($ filename, $ data) to download .csv file to solve file name garbled and file content garbled. After a long time, I finally learned a good solution.

1. attach auxiliary functions

$ This-> load-> helper ('download'); // download helper functions $ this-> load-> helper ('string'); // character encoding conversion helper book Turning

2. force_download ($ filename, $ data) uses its code to know that $ data must be a string. if it is not a string, an error occurs. Is an array and must be converted to a string. use the implode function. for the usage of this function, see the official website. my project code is as follows.

Public function download () {// output the Excel file header // solves the problem of garbled characters in IE, firework, and other browser file names $ filename = 'Retrieved data .csv '; $ newarray = array (); the result is a two-dimensional array if ($ this-> input-> get ()! = False) {$ conn = $ this-> getformdata ();} // output the name of the Excel column $ head = array ('id', 'remittance no ', 'remittance amount (points) ', 'adjustment channel cost', 'remittance time', 'import SO time', 'Channel name', 'contract ID '); foreach ($ head as $ I =>$ v) {// CSV Excel supports GBK encoding and must be converted, otherwise, garbled code $ head [$ I] = utf2gbk ($ v);} $ newarray [] = implode (',', $ head ); $ SQL = "select * from sinapay_boss_income where {$ conn} order by income_status asc, boss_income_id desc"; $ query = $ this-> db-> query ($ SQL ); // counter $ cnt = 0; // refresh the output buffer every $ limit row. do not set it to too large or too small $ limit = 8000; foreach ($ query-> result_array () as $ row) {$ cnt ++; if ($ limit = $ cnt) {// refresh the output buffer to prevent problems caused by excessive data. ob_flush (); flush (); $ cnt = 0;} // read table data $ content = array (); $ content [] = $ row ['Boss _ income_id ']; $ content [] = $ row ['Welcome _ num']; $ content [] = $ row ['Welcome _ amount']; $ content [] = $ row ['modified _ cost']; $ content [] = $ row ['Welcome _ date']; $ content [] = $ row ['write _ so_month ']; $ content [] = utf2gbk ($ row ['Channel _ name']); $ content [] = utf2gbk ($ row ['Welcome _ contract_id ']); $ newarray [] = implode (', ', $ content );} $ newarray = implode ("\ n", $ newarray); force_download ($ filename, $ newarray );}}

3. after the test, I found that the IE browser file name is garbled and the firefox browser file name is garbled. So I made the following changes to the helper function, and I added the background color code below.

If (! Function_exists ('force _ download') {function force_download ($ filename = '', $ data = '') {if ($ filename = ''OR $ data ='') {return FALSE;} // the file name in the ie browser is garbled $ filename = urlencode ($ filename ); $ filename = str_replace ("+", "% 20", $ filename); // Try to determine if the filename between Des a file extension. // We need it in order to set the MIME typeif (FALSE === strpos ($ filename ,'. ') {return FALSE;} // Grab t He file extension $ x = explode ('. ', $ filename); $ extension = end ($ x); // Load the mime types @ include (APPPATH. 'config/mimes '. EXT); // Set a default mime if we can't find itif (! Isset ($ mimes [$ extension]) {$ mime = 'application/octet-stream';} else {$ mime = (is_array ($ mimes [$ extension])? $ Mimes [$ extension] [0]: $ mimes [$ extension];} // Generate the server headersif (strstr ($ _ SERVER ['http _ USER_AGENT '], "MSIE") {header ('content-Type :"'. $ mime. '"'); header ('content-Disposition: attachment; filename = "'. $ filename. '"'); header ('expires: 0'); header ('cache-Control: must-revalidate, post-check = 0, pre-check = 0 '); header ("Content-Transfer-Encoding: binary"); header ('pragma: public'); header ("Content-Length :". strlen ($ data);} elseif (strstr ($ _ SERVER ['http _ USER_AGENT '], "Firefox ")) {// Fix the garbled header ('content-Type :"'. $ mime. '"'); header ('content-Disposition: attachment; filename * =" utf8 \'\''. $ filename. '"'); header ('expires: 0'); header ('cache-Control: must-revalidate, post-check = 0, pre-check = 0 '); header ("Content-Transfer-Encoding: binary"); header ('pragma: public'); header ("Content-Length :". strlen ($ data);} else {header ('content-Type :"'. $ mime. '"'); header ('content-Disposition: attachment; filename = "'. $ filename. '"'); header (" Content-Transfer-Encoding: binary "); header ('expires: 0'); header ('pragma: no-cache '); header ("Content-Length :". strlen ($ data) ;}exit ($ data );}}
