我通过IMAP连接从邮箱获取XLSX附件,以便我可以使用PHPExcel将这些电子表格转换为PHP数组数据,但是当我加载文件并将其转换为数组时,数组为空。
这是从符合条件的邮件中获取附件的功能:
public function getEmailAttachments($criteria){
$emails = imap_search($this->inbox, $criteria);
$email_attachments = [];
if($emails) {
rsort($emails);
foreach ($emails as $email_number) {
$attachments = [];
//get Email structure
$structure = imap_fetchstructure($this->inbox, $email_number);
/* if any attachments found... */
if(isset($structure->parts) && count($structure->parts))
{
for($i = 0; $i < count($structure->parts); $i++)
{
$attachments[$i] = array(
'is_attachment' => false,
'filename' => '',
'name' => '',
'attachment' => ''
);
if($structure->parts[$i]->ifdparameters)
{
foreach($structure->parts[$i]->dparameters as $object)
{
if(strtolower($object->attribute) == 'filename')
{
$attachments[$i]['is_attachment'] = true;
$attachments[$i]['filename'] = $object->value;
}
}
}
if($structure->parts[$i]->ifparameters)
{
foreach($structure->parts[$i]->parameters as $object)
{
if(strtolower($object->attribute) == 'name')
{
$attachments[$i]['is_attachment'] = true;
$attachments[$i]['name'] = $object->value;
}
}
}
if($attachments[$i]['is_attachment'])
{
$attachments[$i]['attachment'] = imap_fetchbody($this->inbox, $email_number, $i+1);
/* 3 = BASE64 encoding */
if($structure->parts[$i]->encoding == 3)
{
$attachments[$i]['attachment'] = base64_decode($attachments[$i]['attachment']);
}
/* 4 = QUOTED-PRINTABLE encoding */
elseif($structure->parts[$i]->encoding == 4)
{
$attachments[$i]['attachment'] = quoted_printable_decode($attachments[$i]['attachment']);
}
}
}
}
$email_attachments = array_merge($email_attachments, array_filter($attachments, function($attachment){return $attachment['is_attachment'] == 1;}));
}
}
imap_close($this->inbox);
return $email_attachments;
}
然后,这是将XLSX文件写入服务器并使用PHPExcel加载它们以将它们转换为数据数据的函数:
public function getEmailReports(){
$this->loadPhpExcel();
$attachments = parent::getEmailAttachments('FROM "example@example.com"');
//iterate through each attachment and save it
foreach($attachments as $attachment){
$filename = $attachment['name'];
if(empty($filename)) $filename = $attachment['filename'];
$folder = "data/excel";
$file_path = "./". $folder ."/". time() . "-" . $filename;
$fp = fopen($file_path, "w");
fwrite($fp, $attachment['attachment']);
$excelReader = PHPExcel_IOFactory::createReaderForFile($file_path);
$excelObj = $excelReader->load($file_path);
foreach ($excelObj->getWorksheetIterator() as $worksheet) {
$worksheets[$worksheet->getTitle()] = $worksheet->toArray();
}
fclose($fp);
print_r($worksheets); //ARRAY IS EMPTY HERE
//unlink($file_path);
}
}
答案 0 :(得分:1)
我用WinRAR打开了XLSX文件,发现xl / worbooks.xml文件有一个&#34; S&#34;命名空间:
<?xml version="1.0"?>
<s:workbook
xmlns:s="http://schemas.openxmlformats.org/spreadsheetml/2006/main" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships">
<s:workbookPr/>
<s:bookViews>
<s:workbookView activeTab="0"/>
</s:bookViews>
<s:sheets>
<s:sheet r:id="rId1" sheetId="1" name="Sheet1"/>
<s:sheet r:id="rId2" sheetId="2" name="Sheet2"/>
<s:sheet r:id="rId3" sheetId="3" name="Sheet3"/>
<s:sheet r:id="rId4" sheetId="4" name="Sheet4"/>
</s:sheets>
<s:definedNames/>
<s:calcPr fullCalcOnLoad="1" calcId="124519"/>
</s:workbook>
然后我在PHPExcel GitHub repo https://github.com/PHPOffice/PHPExcel/issues/571
上发现了这个问题所以我所做的就是创建一个从PHPExcel_Reader_Excel2007扩展的类来删除&#34; s&#34;命名空间
<?php
class PHPExcel_Reader_Excel2007_XNamespace extends
PHPExcel_Reader_Excel2007
{
public function securityScan($xml)
{
$xml = parent::securityScan($xml);
return str_replace(['<s:', '</s:'], ['<', '</'], $xml);
}
}
最后取代了这个:
$excelReader = PHPExcel_IOFactory::createReaderForFile($file_path);
为此:
$excelReader = new PHPExcel_Reader_Excel2007_XNamespace();
