Pass array to Excel - php

Question

I am using (trying to use) PHPExcel to pass an array to excel, I have defined the headings and i want every array in the array to in a separate row.
However, this only puts the headings in the excel file and not the data from the array. What am i doing wrong?How can I get this to work?
Script:
<?php
$databasehost = "localhost";
$databasename = "dummydata";
$databasetable = "import1";
$databasetable2 = "data1";
$databaseusername ="dummydata";
$databasepassword = "dummydata";
$con = #mysql_connect($databasehost,$databaseusername,$databasepassword) or die(mysql_error());
#mysql_select_db($databasename) or die(mysql_error());
$query = mysql_query("SELECT * from $databasetable;");
$data = array();
$index = 0;
while($row = mysql_fetch_assoc($query))
{
$data[$index] = $row;
$index++;
}
foreach ($data as $key) {
$url = 'http://maps.googleapis.com/maps/api/geocode/json?latlng='.$key['latitude'].','.$key['longitude'].'&sensor=true';
$json = file_get_contents($url);
$dataReceived = json_decode($json, TRUE);
//echo '<pre>'; print_r($dataReceived['results']); echo '</pre>';
$compiled = array();
$index = 0;
foreach ($dataReceived['results'] as $value) {
$compiled[$index] = array(
'ref' => $key['id']);
foreach ($value['address_components'] as $value2)
{
$compiled[$index][$value2['types'][0]] = $value2['long_name'];
}
$index++;
}
$sortedData = array();
$index = 0;
foreach ($compiled as $value) {
//echo '<pre>'; print_r($value); echo '</pre>';
$sortedData[$index] = array(

Answer 1

Just re-reading your code and it looks rather chaotic. I think it can be improved in many areas, however with the least changes I suggest you do the following:
Instead of first creating multiple arrays of rows you want to add, add a new row each time you have created it. For that you do not even need to name the keys. So before you iterate through the database results, first create the headers (I named it $headers):
$headers = array(
'ref', 'lat', 'long', 'route', 'locality', 'administrative_area_level_2',
'administrative_area_level_1', 'country', 'postal_code_prefix',
'postal_town', 'postal_code', 'administrative_area_level_3',
'street_number', 'establishment',
);
Also before the database iteration, create a helper-function:
$addRowCreate = function(PHPExcel_Worksheet $sheet, $col = 'A', $row = NULL) {
return function(array $data) use ($sheet, $col, &$row) {
if ($row === NULL) {
$row = $sheet->getHighestRow() + 1;
}
$sheet->fromArray(array($data), NULL, "$col$row");
$row++;
};
};
This $addRowCreate helper function will allow you to create a add-row-function later on, like in just a second. Also before the database iteration, create the excel document (memory) and set it's properties. Also add the headers in the first row:
$doc = new PHPExcel();
$doc->getProperties()->setCreator("Anon")
->setLastModifiedBy("Anon")
->setTitle("Crawler Data");
$sheet = $doc->setActiveSheetIndex(0);
$sheet->fromArray($headers);
The next step is to create the add-row-function, which is very easy thanks to the helper above:
$addRow = $addRowCreate($sheet);
You now can use one row after the other by calling it once per row array. For testing purposes, just add another row and save it to disk:
$addRow($headers);
$writer = PHPExcel_IOFactory::createWriter($doc, 'Excel5');
$writer->save(basename(__FILE__, '.php') . '.xls');
die('test finished.');
You should now have create the xls file with two rows. You can then remove the test again and inside your loops use the $addRow function:
$addRow(array(
'ref' => $value['ref'],
'lat' => $key['latitude'],
'long' => $key['longitude'],
'route' => $value['route'],
'locality' => $value['locality'],
'administrative_area_level_2' => $value['administrative_area_level_2'],
'administrative_area_level_1' => $value['administrative_area_level_1'],
'country' => $value['country'],
'postal_code_prefix' => $value['postal_code_prefix'],
'postal_town' => $value['postal_town'],
'postal_code' => $value['postal_code'],
'administrative_area_level_3' => $value['administrative_area_level_3'],
'street_number' => $value['street_number'],
'establishment' => $value['establishment'],
));
Technically you can remove the string-array-keys, however I've kept them in so that you can better find the place where you need to change your code as the array already exists there-in.
After you've put this to the work, you can safely remove all the not-any-more-needed temporary arrays and counters.
The full usage-example (test):
require_once 'Classes/PHPExcel.php'; /* PHPExcel <http://phpexcel.codeplex.com/> */
$headers = array(
'ref', 'lat', 'long', 'route', 'locality', 'administrative_area_level_2',
'administrative_area_level_1', 'country', 'postal_code_prefix',
'postal_town', 'postal_code', 'administrative_area_level_3',
'street_number', 'establishment',
);
$addRowCreate = function(PHPExcel_Worksheet $sheet, $col = 'A', $row = NULL) {
return function(array $data) use ($sheet, $col, &$row) {
if ($row === NULL) {
$row = $sheet->getHighestRow() + 1;
}
$sheet->fromArray(array($data), NULL, "$col$row");
$row++;
};
};
$doc = new PHPExcel();
$doc->getProperties()->setCreator("Anon")
->setLastModifiedBy("Anon")
->setTitle("Crawler Data");
$sheet = $doc->setActiveSheetIndex(0);
$sheet->fromArray($headers);
$addRow = $addRowCreate($sheet);
$addRow($headers);
$writer = PHPExcel_IOFactory::createWriter($doc, 'Excel5');
$writer->save(basename(__FILE__, '.php') . '.xls');
die('test finished.');
Old Answer:
However, this only puts the headings in the excel file and not the data from the array. What am i doing wrong?
You are actually only storing the headings into the file. You do not store any data.
How can I get this to work?
Bring the array in the right format and uncomment the following line in your code:
//$objPHPExcel->getActiveSheet()->fromArray($sortedData, null, 'A2');
Take care that $sortedData is the needed 2D array, see the examples in this dicsussion:
Array
(
[0] => Array
(
[0] => Relative CellA1
[1] => Relative CellB1
[2] => Relative CellC1
)
[1] => Array
(
[0] => Relative CellA2
[1] => Relative CellB2
[2] => Relative CellC2
)
)
Unless you don't get the array into that kind of 2D format, the function will not work in your favor.
Please let me know if you've got any more questions.

Answer 2

PHPExcel write data to the cell and you must define it position. Just like then you define headers. The principle is that you fill out the document line by line.
So I write example code to show the idea
$alphas = range('A', 'Z'); // A, B, C, D, E...
$sheet = $excel->getActiveSheet();
//headers
$sheet
->setCellValue($alphas[0].'1', 'Title1')
->setCellValue($alphas[1].'1', 'Title2')
->setCellValue($alphas[2].'1', 'Title3')
->setCellValue($alphas[3].'1', 'Title4')
;
$sheet->getColumnDimension($alphas[0])->setWidth(40);
$sheet->getColumnDimension($alphas[1])->setWidth(9);
$sheet->getColumnDimension($alphas[2])->setWidth(60);
$sheet->getColumnDimension($alphas[3])->setWidth(30);
$items = ...;// <--- your data
$row_num = 2; // start from 2 row
foreach($items as $item) {
$sheet->setCellValue($alphas[0].$row_num, $item['key1']);
$sheet->setCellValue($alphas[1].$row_num, $item['key2']);
$sheet->setCellValue($alphas[2].$row_num, $item['key3']);
$sheet->setCellValue($alphas[3].$row_num, $item['key4']);
$row_num++;
}

Answer 3

You can create a generic function to get excel content from any 2D arrays.
PHP array2xlsx function
/**
* This function returns xlsx content from an associative array.
*
* Warning: one cell = about 1k memory, so this function does not work
* if your array is too large.
*
* #param array $array
* #param string $title
* #param string $author
* #return string
*/
function array2xlsx(array &$array, $title = 'New Document', $author = null)
{
// Basic checks
if (count($array) == 0)
{
return null;
}
// Putting meta-data into a new excel file
$ex = new PHPExcel();
$ex->getProperties()->setLastModifiedBy($title);
$ex->getProperties()->setTitle($title);
$ex->getProperties()->setSubject($title);
$ex->getProperties()->setDescription($title);
$ex->getProperties()->setCreator($author);
// Select first page on the excel document
$ex->setActiveSheetIndex(0);
$sheet = $ex->getActiveSheet();
// Writes column titles on row 1 (assuming column names are array keys)
$column_names = array_keys(reset($array));
foreach ($column_names as $column_number => $column_name)
{
$azNumber = PHPExcel_Cell::stringFromColumnIndex($column_number);
$sheet->SetCellValue($azNumber . "1", $column_name);
}
// Writes document content
foreach ($array as $row_number => $row)
{
foreach (array_values($row) as $column_number => $cell_content)
{
// Converts column numbers to alphabetic numbering
$azNumber = PHPExcel_Cell::stringFromColumnIndex($column_number);
$sheet->SetCellValue($azNumber . ($row_number + 2), $cell_content);
}
}
// Creates file contents
$writer = new PHPExcel_Writer_Excel2007($ex);
ob_start();
$writer->save("php://output");
$content = ob_get_contents();
ob_end_clean();
return $content;
}
And send it directly to your user, by sending proper headers.
PHP download_send_header function
function download_send_headers($filename) {
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
header("Content-Disposition: attachment;filename={$filename}");
header("Content-Transfer-Encoding: binary");
}
PHP Usage example
// We simulate your array
$array = array();
for ($i = 0; ($i < 50); $i++)
{
$array[$i] = array(
'ref' => "ref {$i}",
'lat' => "lat {$i}",
'long' => "long {$i}",
'route' => "route {$i}",
'locality' => "locality {$i}",
'administrative_area_level_2' => "administrative area level 2 {$i}",
'administrative_area_level_1' => "administrative area level 1 {$i}",
'country' => "country {$i}",
'postal_code_prefix' => "postal_code_prefix {$i}",
'postal_town' => "postal_town {$i}",
'postal_code' => "postal code {$i}",
'administrative_area_level_3' => "administrative area level 3 {$i}",
'street_number' => "street number {$i}",
'establishment' => "establishment {$i}",
);
}
// We send headers and excel content from your array
download_send_headers("my_test.xlsx");
echo array2xlsx($array);
Result
