csv export formatting

[biggie]

Hi all,

I am using the following code to export a table of data from SQL to CSV format.

header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=UserData.csv");
header("Pragma: no-cache");
header("Expires: 0");


mysql_select_db($database_conf, $conf);
$select = "SELECT username, email, , organisation, selections FROM users";
$export = mysql_query($select);
$count = mysql_num_fields($export);
for ($i = 0; $i < $count; $i++) {
$header .= mysql_field_name($export, $i).",";
}
while($row = mysql_fetch_row($export)) {
$line = '';
foreach($row as $value) {
if ((!isset($value)) OR ($value == "")) {
$value = "\t";
} else {
$value = str_replace('"', '""', $value);
$value = '"' . $value . '"' . ",";
}
$line .= $value;
}
$data .= trim($line)."\n";
}
$data = str_replace("\r", "", $data);
if ($data == "") {
$data = "\n(0) Records Found!\n";
}
print "$header\n$data";
exit;

This works great however the final column 'selections' may sometimes be in the format of 21, 34, 56 or in a single number.

Is it possible to output the values stored with commas into separate columns. e.g...

|Selections| | |
--------------------------
| 21 | 11 | 40 |

Thanks!

After fetching the data of the last column, replace the commas in that with a | . str_replace(',' '|', $value);

Hi,

thanks for your reply, not sure i explained myself correctly though.

I don't want to replace the commas with a |. I need to split the commad values up into their own columns.

So for instance instead of this in Excel:



i want it to look like:



thanks again!

It is a csv file right? Commas in the column should automatically put them in separate cells. But since you are using " to enclose the values that might not be happening. What you can do is split the string at commas and assign them like you are doing the regular values.

$tval = explode(',', $value);
foreach($tval as $v){
  $value .= '"'.$v.'",';
}

Thanks for your reply.

Not too sure where i would implement this within my code, any ideas?

thanks again

I added the following to the code:

while($row = mysql_fetch_row($export)) {
$line = '';
$a = 0;
foreach($row as $value) {
if ((!isset($value)) OR ($value == "")) {
$value = "\t";
} else {
$value = str_replace('"', '""', $value);
//$value = '"' . $value . '"' . ",";
$tval = explode(',', $value);
$value .= $tval[$a].',';
$a = $a + 1;
}
$line .= $value;
}
$data .= trim($line)."\n";
}
$data = str_replace("\r", "", $data);

This separates the values into separate columns but for some reason the first column is repeating itself, for example the user Joe Bloggs would be displayed as: Joe BloggsJoe Bloggs

help with this si appreciated,

thanks

while($row = mysql_fetch_row($export)) {
    $line = '';
    $count = count($row);
    for($i=0;$i<$count;$i++){
        if ((!isset($row[$i])) OR ($row[$i] == "")) {
            $value = "\t";
        } else {
            if ($i == ($count-1)){ //last column
                $tval = explode(',', $row[$i]);
                $value = '';
                foreach($val as $v)
                    $value .= '"'.$v.'",';
            }
            else{    
                $value = str_replace('"', '""', $row[$i]);
                $value = '"' . $value . '"' . ",";
            }        
        }
        $line .= $value;
    }
    $data .= trim($line)."\n";
}
$data = str_replace("\r", "", $data);
