Examples of php exporting and importing csv files

t10

header("Content-type:application/vnd.ms-excel"); header("content-Disposition:filename=downloaded.pdf "); echo "1t 2t 3n"; //where t is blank and n is carriage return (encoding specifications cannot be output directly) echo "1t 2t 3n"; echo "1t 2t 3n"; ?> When you open this php file, you will be prompted to download it. It can also be output in the form of a table; header("Content-type:application/vnd.ms-excel "); header("content-Disposition:filename=downloaded.pdf"); ?> < ;table>

Second, use the fpubcsv() function to write the csv file. example:

$fp = fopen('f:/file.csv', 'w');
fputcsv($fp,array('aaa','bbb','cccc') ;
