Question

I’m exporting some mysql data to a text file. The data can be selected by checkboxes from a table.

I want to format the text that will be in text file. How do I do that?

This is my code:

 <?php
if ($_POST['exporttxt']) {
for($i=0;$i<count($_POST['checkbox']);$i++){
   $export_id = $checkbox[$i];
$text = mysql_query("SELECT code FROM tickets WHERE id='$export_id'");
$text = mysql_fetch_assoc($text);
$text = $text["code"];
$filename = "export";
$filedate = date("Y-m-d");
$fileext = ".txt";
$fileall = $filename.$filedate.$fileext;
ob_end_clean();
    header("Content-Type: application/octet-stream");
header("Content-disposition: attachment;filename=\"$fileall\"");
   header("Content-Type: application/force-download");

    header("Content-Type: application/download");
    header("Content-Description: File Transfer");
    header("Content-Length: ".strlen($output).";\n");



echo($text);


}
}

exit();

?>

The data that will be exported are numbers containing of 16 digits. After every number I want to have a line-break. Also if possible I would like to have a space after 4 digits for every number, example:

Number non-formatted: 1234567891234567
Number formatted: 1234 5678 9123 4567

How can I do that?

Answer 1

Use chunk_split

echo chunk_split($text, 4, " "); <-- you seems forgotten a line break

Off-topic issue :-

1. where is $output defined ?
2. you don’t have ob_start()
3. repeatedly use $text for various data type( mysql result resource, array, string)
