我有一些我想导出的 mysql 表的结果，我目前可以单击下载链接并下载 xls，但我希望能够通过 cron 作业运行它并将每周结果通过电子邮件发送给我.
我已经研究过从 Mysql 执行此操作并将其直接保存为 csv。
但是我正在努力使用SQL，表格格式如下
btFormQuestions (some columns ommitted)
+-------+---------------+----------+-----------+
| msqID | questionSetId | Question | InputType |
|-------+---------------+----------+-----------+
| 1 | 123456 | Name | field |
| 2 | 123456 | Telephone| field |
| 3 | 123456 | Email | email |
| 4 | 123456 | Enquiry | test |
btFormAnswers
+-----+------+-------+-----------------+
| aID | asID | msqID | answer |
+-----+------+-------+-----------------+
| 1 | 1 | 1 | Sean |
| 2 | 1 | 2 | 0800 0 |
| 3 | 1 | 3 | se@te.com |
| 4 | 1 | 4 | Asking Question |
btFormAnswersSet
+------+---------------+---------------------+
| asID | questionSetId | created |
+------+---------------+---------------------+
| 1 | 123456 | 2013-04-30 11:07:55 |
我目前用于将信息输入 PHP 并输入数组的 sql 查询如下：
//get answers sets
$sql='SELECT * FROM btFormAnswerSet AS aSet '.
'WHERE aSet.questionSetId='.$questionSet.' ORDER BY created DESC LIMIT 0, 100;
$answerSetsRS=$db->query($sql);
//load answers into a nicer multi-dimensional array
$answerSets=array();
$answerSetIds=array(0);
while( $answer = $answerSetsRS->fetchRow() ){
//answer set id - question id
$answerSets[$answer['asID']]=$answer;
$answerSetIds[]=$answer['asID'];
}
//get answers
$sql='SELECT * FROM btFormAnswers AS a WHERE a.asID IN ('.join(',',$answerSetIds).')';
$answersRS=$db->query($sql);
//load answers into a nicer multi-dimensional array
while( $answer = $answersRS->fetchRow() ){
//answer set id - question id
$answerSets[$answer['asID']]['answers'][$answer['msqID']]=$answer;
}
return $answerSets;
我希望能够执行以下操作之一
A.) 将所有这些移到一个查询中，以便能够获得以下类型的结果
+---------------+------+-----------+-----------+-----------------+
| QuestionSetID | Name | Telephone | Email | Enquiry |
+---------------+------+-----------+-----------+-----------------+
| 123456 | Sean | 0800 0 | se@te.com | Asking Question |
（我确实尝试了各种连接，但无法完全正确） 如果我能让它工作，我不介意保存为 CSV
B.) 将返回的数组输出为 excel 文件，可以保存到服务器上的某个位置，
当前代码从数组创建一个 html 表
代码有点长，所以我只在这里粘贴顶部和底部位
//fwrite($handle, $excelHead);
//fwrite($handle, $row);
//fflush($handle);
ob_start();
header("Content-Type: application/vnd.ms-excel");
echo "<table>\r\n";
//Question headers go here
foreach($answerSets as $answerSetId=>$answerSet){
$questionNumber=0;
$numQuestionsToShow=2;
echo "\t<tr>\r\n";
echo "\t\t<td>". $dateHelper->getSystemDateTime($answerSet['created'])."</td>\r\n";
foreach($questions as $questionId=>$question){
$questionNumber++;
if ($question['inputType'] == 'checkboxlist'){
$options = explode('%%', $question['options']);
$subanswers = explode(',', $answerSet['answers'][$questionId]['answer']);
for ($i = 1; $i <= count($options); $i++)
{
echo "\t\t<td align='center'>\r\n";
if (in_array(trim($options[$i-1]), $subanswers)) {
// echo "\t\t\t".$options[$i-1]."\r\n";
echo "x";
} else {
echo "\t\t\t \r\n";
}
echo "\t\t</td>\r\n";
//fwrite($handle, $node);
//fflush($handle);
}
}elseif($question['inputType']=='fileupload'){
echo "\t\t<td>\r\n";
$fID=intval($answerSet['answers'][$questionId]['answer']);
$file=File::getByID($fID);
if($fID && $file){
$fileVersion=$file->getApprovedVersion();
echo "\t\t\t".'<a href="'. $fileVersion->getDownloadURL() .'">'.$fileVersion->getFileName().'</a>'."\r\n";
}else{
echo "\t\t\t".t('File not found')."\r\n";
}
echo "\t\t</td>\r\n";
}else{
echo "\t\t<td>\r\n";
echo "\t\t\t".$answerSet['answers'][$questionId]['answer'].$answerSet['answers'][$questionId]['answerLong']."\r\n";
echo "\t\t</td>\r\n";
}
//fwrite($handle, $node);
//fflush($handle);
}
echo "\t</tr>\r\n";
//fwrite($handle, $row);
//fflush($handle);
}
echo "</table>\r\n";
//fwrite($handle, $excelFoot);
//fflush($handle);
//fclose($handle);
file_put_contents($filePath, ob_get_clean());
我可以将文件保存到目录中，但在将其设置为 Excel 文件时遇到问题，我也尝试过使用 Fwrite （而不是缓冲区）播放，结果相似
任何人都可以帮助，或指出我在正确的位置。
谢谢你，肖恩
