mysql - Export database results to CSV with PHP -


i've trauled through site , found tonnes of threads same thing none complete novice me dont understand answers properly.

i have selected data database , displayed in table on webpage. need link below table export data csv file.

one of answers have found on site is: create csv file user in php

however answer doesnt make sense me , dont know code.

here code answer:

header("content-type: text/csv"); header("content-disposition: attachment; filename=file.csv"); header("pragma: no-cache"); header("expires: 0");  $array = array(     array("data11", "data12", "data13"),     array("data21", "data22", "data23"),     array("data31", "data32", "data23")); outputcsv($array);  function outputcsv($data) {     $outstream = fopen("php://output", "w");     function __outputcsv(&$vals, $key, $filehandler) {         fputcsv($filehandler, $vals); // add parameters if want     }     array_walk($data, "__outputcsv", $outstream);     fclose($outstream); }

i have many questions need create excel file first? if need blank?

what this?:

$array = array(     array("data11", "data12", "data13"),     array("data21", "data22", "data23"),     array("data31", "data32", "data23"));

is supposed data? how change suit data have?

why call function before function defined?

what these variables in function ($vals, $key, $filehandler) , created?

how use code because many people seem think perfect.

i need start finish complete php novice

ive worked on 1 of answers below , have code

$i=0;                         $csv="";                         ($a=0; $a<=$count; $a++) {                             $i++;                             $csv.=preg_replace("/\n/",'',preg_replace("/,/",';',$serveys[$a]['feedbackname'])).",".                                   preg_replace("/\n/",'',preg_replace("/,/",';',$serveys[$a]['branchname']));                             $csv.="\n";                         }                          if ($i>0) {                             header("pragma: public");                             header("expires: 0");                             header("cache-control: must-revalidate, post-check=0, pre-check=0");                             header("cache-control: private",false);                             header("content-type: application/octet-stream");                             header("content-disposition: attachment; filename=\"table.csv\";" );                             header("content-transfer-encoding: binary");                              echo $csv;                         } else {                             return "nothing download!";                         }

when run page though there no change, data still displayed on page should be. no csv file created , no errors occurr

the code created new file object, outputs standard output, offered user download because of headers sent before.

that data; array of associative arrays. how fill you.

the call function before defined because php first parses file @ top level completely, function defined when called. not apply functions inside if statements.

the values function provided standard function fputcsv.

you use code presented.
