PHPExcel how to set cell value dynamically

Solution 1:

I asume you have connected to your database already.

$sql = "SELECT * FROM my_table";
$result = mysql_query($sql);

$row = 1; // 1-based index
while($row_data = mysql_fetch_assoc($result)) {
    $col = 0;
    foreach($row_data as $key=>$value) {
        $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $value);
        $col++;
    }
    $row++;
}

Solution 2:

I don't have much experience working with php but from a logic standpoint this is what I would do.

1. Loop through your result set from MySQL
2. In Excel you should already know what A,B,C should be because those are the columns and you know how many columns you are returning.
3. The row number can just be incremented with each time through the loop.

Below is some pseudocode illustrating this technique:

    for (int i = 0; i < MySQLResults.count; i++){
         $objPHPExcel->getActiveSheet()->setCellValue('A' . (string)(i + 1), MySQLResults[i].name); 
        // Add 1 to i because Excel Rows start at 1, not 0, so row will always be one off
         $objPHPExcel->getActiveSheet()->setCellValue('B' . (string)(i + 1), MySQLResults[i].number);
         $objPHPExcel->getActiveSheet()->setCellValue('C' . (string)(i + 1), MySQLResults[i].email);
    }
