Introduction: This is a detailed page for PHP output and CSV writing. It introduces the related knowledge, skills, experience, and some PHP source code.

1. First, use the header () in PHP.

For more information, see the PHP header () function and P in w3school.HPMediumEnableUseHEADERLetterQuantityOfHTTPHeaderSetSet.

The Header () function must be called before any actual output is sent.

Below is a CSV sample output in PHP.

 

1. Define the header output format

Header ("Content-Type: Application/vnd. MS-excel"); // defines the output file type

Header ("Content-Disposition: filename =downloaded.pdf"); // Define the output file name, that is, set a download type. The file is renamed during download.

 

<? PHP
Header ("Content-Type: Application/vnd. MS-excel ");
Header ("content-Disposition: filenameappsdownloaded.pdf ");

Echo "1 \ t 2 \ t 3 \ n"; // where \ t is blank and \ n is carriage return (encoding specifications cannot be output directly)
Echo "1 \ t 2 \ t 3 \ n ";
Echo "1 \ t 2 \ t 3 \ n ";

?>

 

In this case, you can open the PHP file and a prompt will be displayed for download.

 

It can also be output as a table;

<? PHP
Header ("Content-Type: Application/vnd. MS-excel ");
Header ("content-Disposition: filenameappsdownloaded.pdf ");
?>
<Table>
<Tr>
<TD> t00 </TD> <TD> t01 </TD> <TD> t02 </TD>
</Tr>
<Tr>
<TD> T10 </TD> <TD> T11 </TD> <TD> T12 </TD>
</Tr>
<Tr>
<TD> T20 </TD> <TD> T21 </TD> <TD> T22 </TD>
</Tr>
</Table>

 

CSV write operation:

For use of fputcsv (), refer.

 

$ Fp = fopen ('f:/file.csv ', 'w ');
Fputcsv ($ FP, array ('aaa', 'bbb ', 'cccccc '));
Fputcsv ($ FP, array ('mmm', 'yyy', 'hahaha'); // fputcsv () can be implemented using array loops.
Fclose ($ FP );
