Question

我正在使用（尝试使用）PHPExcel将数组传递给excel，我已经定义了标题，我希望数组中的每个数组都在一个单独的行中。

但是，这只会将标题放在excel文件中，而不是数组中的数据。我做错了什么？我怎样才能让它发挥作用？

脚本：

<?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(
                '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'],

                'administrative_area_level_3' => $value['administrative_area_level_3'],
                'street_number' => $value['street_number'],
                'establishment' => $value['establishment'],
            ); 
        $index++;

    }   
    echo '<pre>';print_r($sortedData);echo "</pre>";
    /*$query = mysql_query("INSERT INTO $databasetable2
                ref, lat, long, route, locality, administrative_area_level_2, administrative_area_level_1, country, postal_code_prefix, postal_town)

}

Answer 1

重新阅读你的代码，它看起来很混乱。我认为可以在许多方面进行改进，但是对于最少更改，我建议您执行以下操作：

不是首先创建要添加的多个行数组，而是每次创建时添加一个新行。为此，您甚至不需要为键命名。所以在之前迭代数据库结果，首先创建标题（我将其命名为$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',
);

同样在数据库迭代之前，创建一个辅助函数：

$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++;
    };
};

这个$addRowCreate辅助函数将允许您稍后创建一个add-row-function，就像在一秒钟内一样。在数据库迭代之前，创建excel文档（内存）并设置它的属性。还要在第一行添加标题：

$doc = new PHPExcel();
$doc->getProperties()->setCreator("Anon")
    ->setLastModifiedBy("Anon")
    ->setTitle("Crawler Data");

$sheet = $doc->setActiveSheetIndex(0);
$sheet->fromArray($headers);

下一步是创建add-row-function，由于上面的帮助器，非常很容易：

$addRow = $addRowCreate($sheet);

现在，您可以通过每行数组调用一次来使用一行。出于测试目的，只需添加另一行并将其保存到磁盘：

$addRow($headers);
$writer = PHPExcel_IOFactory::createWriter($doc, 'Excel5');
$writer->save(basename(__FILE__, '.php') . '.xls');
die('test finished.');

您现在应该创建包含两行的xls文件。然后，您可以再次删除测试，并在内部您的循环中使用$addRow函数：

$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'],
));

从技术上讲，你可以删除string-array-keys，但是我保留了它们，这样你就可以更好地找到你需要更改代码的地方，因为数组已存在。

在完成这项工作之后，您可以安全地删除所有不再需要的临时数组和计数器。

完整用法示例（测试）：

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.');

旧答案：

但是，这只会将标题放在excel文件中，而不是数组中的数据。我做错了什么？

实际上，您只是将标题存储到文件中。您不存储任何数据。

我怎样才能让它发挥作用？

以正确的格式显示数组并取消注释代码中的以下行：

//$objPHPExcel->getActiveSheet()->fromArray($sortedData, null, 'A2');

注意$sortedData是所需的2D数组，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
        )

)

除非您没有将数组转换为那种类型的2D格式，否则该功能对您不利。

Answer 2

PHPExcel将数据写入单元格，您必须定义它的位置。就像那样你定义标题。原则是您逐行填写文档。所以我编写示例代码来显示想法

$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

您可以创建一个通用函数来从任何2D数组中获取excel内容。

PHP array2xlsx函数

/**
 * 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;
}

通过发送正确的标题将其直接发送给您的用户。

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 用法示例

// 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);

结果
