I'm trying to export an array of arrays to excel. I have it set up to be a header variable, and a data variable that basically builds a giant string to be executed in the export. However, only the header variable is going through. Let me show some code:

This is setting the parameters:

    str_replace(" ", "_", $getData['name']);
    $filename = $getData['name']."_summary.xls";
    header("Content-Type: application/x-msdownload");
    header("Content-Disposition: attachment; filename=\"$filename\"");
    header("Pragma: no-cache");
    header("Expires: 0");

Which goes to a function to get the informa开发者_JS百科tion:

foreach($tempRS as $key=>$value)
{
    foreach($value as $iKey=>$iValue)
    {
        if($count == 6)
        {
            $iValue = str_replace('"', '""', $iValue);
            $iValue = '"'.$iValue.'"'."\n";
            $data .= trim($iValue);
            $count = 0;
        }
        else
        {
            $iValue = str_replace('"', '""', $iValue);
            $iValue = '"'.$iValue.'"'."\t";
            $data .= trim($iValue);
            $count++;
        }
    }

}
$header = "ROW HEADER 1\tROW HEADER 2\tROW HEADER 3\tROW HEADER 4\tROW HEADER 5\tROW HEADER 6\n";
print "$header\n$data";

I can't seem to figure out why i'm losing the $data variable on the export.


Why not just fputcsv() to generate that CSV data for you? Or better yet, instead of making a .csv masquerade as an Excel file, you can use PHPExcel to output a native .xls/.xlsx and actually use formatting and formulae in the generated spreadsheet.


first of all, use echo instead of print. Print causes loads of overhead as it does both return and echo the data.

Secondly, don't put the variables within quotes, use

echo $header ."\n".$data;

To get to your question, does the foreach loops actually loop? Have you checked the $data if it contains any data?

A better solution might be this:

$header = '';
echo $header;

foreach() loop here {
    //echo the data here instead of putting it in a variable
} 

Or maybe better, use http://nl.php.net/fputcsv


I tested your code and it seems that your trim() method is trimming your \n and \t.

If you remove it, your code should be fine.

Here's my code to export a array of product in excel.

Only one little problem with this code : Excel doesn't want to open it because of a format problem, but if you click "yes" when it promps an error message, you'll be ok...

No problem with open office though

Working on a fix...

$filename = "products_exports " . date("Y-m-d H_i_s") . ".xls";

/**
 * Tell the browser to download an excel file.
 */

header("Content-Type: application/x-msdownload; charset=utf-8");
header("Content-Disposition: attachment; filename=\"$filename\"");
header("Pragma: no-cache");
header("Expires: 0");


/**
 * The header of the table
 * @var string
 */
$header = "";
/**
 * All the data of the table in a formatted string
 * @var string
 */
$data = "";

//We fill in the header
foreach ($productArray as $i => $product) {
    $count = 0;
    foreach ($product as $key => $value) {

        if($count == count((array)new Product("")) - 1){
            $header.= $key;
        }
        else{
            $header.= $key . "\t";
            $count++;
        }
    }

    break; /*One loop is enough to get the header !*/
}


//And then the data by the product and all the categories

/*Where $productArray = This can be your custom array of object. eg.
  array[0] = new YouCustomObject(your params...);
*/
foreach ($productArray as $i => $product) {
    $count = 0;
    foreach ($product as $key => $value) {
        if($count == count((array)new Product("")) - 1){
            $value = str_replace('"', '""', $value);
            $value = '"' . $value . '"' . "\n";
            $data .= $value;
            $count = 0;
        }
        else{
            $value = str_replace('"', '""', $value);
            $value = '"' . $value . '"' . "\t";
            $data .= $value;
            $count++;
        }
    }
}

echo $header ."\n". $data;
0
