PHPExcel在xls和xlsx之间切换

I am writing a script that reads .xls and .xlsx files from mail attachments. I'm trying to make the script switch between readers based on the file extension using the identify method.

$strSheetNameResult = 'QA Result';
$strSheetNameComments = 'QA Comments'; 

foreach($aPaths as $strPath) {
    try {
        $strFileType = PHPExcel_IOFactory::identify($strPath);
        echo $strFileType;

        $oReader = PHPExcel_IOFactory::createReader($strFileType);

        $oReader->setLoadSheetsOnly($strSheetNameResult);

        $oSheetData = $oReader->load($strPath)->getActiveSheet();

.xls works just fine, but as soon as it encounters an .xlsx file it doesn't use the right reader and gives me an error: `Fatal error:

Call to a member function getCell() on a non-object in C:\xampp\htdocs\cronjob\Test.php on line 37`

line 37:

$aSheetData['strProjectName'] = $oSheetData->getCell('B4')->getValue();

I think this error is caused because it's not using the right reader.

$aPaths:

Array(
    [0] => C:\xampp\tmp\105943-632345.xls
    [1] => C:\xampp\tmp\112047-634744.xlsx
    [2] => C:\xampp\tmp\112069-634917.xls
    [3] => C:\xampp\tmp\113840-634955.xls

    [19] => C:\xampp\tmp\134508-644581.xls
    [20] => C:\xampp\tmp\134511-646521.xls
    [21] => C:\xampp\tmp\134512-646136.xls
    [22] => C:\xampp\tmp\134561-650010.xls

)

Does anybody have an idea why this isn't working, or a different way to switch between readers?

There was a corrupt file in the list that identified as an xls file but was an xlsx file. I deleted the file and it works perfectly now!

you can try:

    $file_types = explode(".", 'C:\xampp\tmp\105943-632345.xls');
    $file_type = strtolower($file_types [count($file_types) - 1]);

    if($file_type=='xls') {
        $objReader = PHPExcel_IOFactory::createReader('Excel5');
    }elseif($file_type=='xlsx'){
        $objReader = PHPExcel_IOFactory::createReader('Excel2007');
    }else{
        echo 'file type error!';
        exit;
    }
