我已经包含了一个代码在我的php形式附加文件，请找到下面的代码。在我的代码中，我提到只接受*.doc， *.docx和*.pdf，但它接受所有扩展名

function checkType() {
                    if(!empty($_FILES['fileatt']['type'])){
                        if(($_FILES['fileatt']['type'] != "application/msword")||($_FILES['fileatt']['type'] != "application/vnd.openxmlformats-officedocument.wordprocessingml.document")||($_FILES['fileatt']['type'] != "application/pdf")) {
                            echo "Sorry, current format is <b> (".$_FILES['fileatt']['type'].")</b>, only *.doc, *.docx and *.pdf are allowed." ;
                            }
                        }
                    }

function checkType() {
    if(!empty($_FILES['fileatt']['type'])){
        $allowed =  array('doc','docx' ,'pdf');
        $filename = $_FILES['fileatt']['name'];
        $ext = pathinfo($filename, PATHINFO_EXTENSION);
        if(!in_array($ext,$allowed) ) {
            echo "Sorry, current format is <b> (".$_FILES['fileatt']['type'].")</b>, only *.doc, *.docx and *.pdf are allowed." ;
            return false;
       }
    }
    return true;
}

if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/jpg")
|| ($_FILES["file"]["type"] == "image/pjpeg")
|| ($_FILES["file"]["type"] == "image/x-png")
|| ($_FILES["file"]["type"] == "image/png"))
&& ($_FILES["file"]["size"] < 20000)

你可以使用下面的命令将图像转换为word格式。或者您可以将扩展存储在数组中，并可以检查有效编码的条件。我只是给你一个想法不是确切的答案

您可以使用in_array()检查扩展

function checkType($data, $ext)
{
    $filename   = $data['name'];
    $pathinfo   = pathinfo($filename, PATHINFO_EXTENSION);
    // Checking
    if(in_array($pathinfo, $ext))
    {
        // TRUE
        return TRUE;
    }
    // FALSE
    return FALSE;
}
$checkType = checkType($_FILES['video_file'], array('doc', 'docx', 'pdf');
var_dump($checkType);
