使用Pdf/Docx而不是图像上传PHP文件

下面我有一个示例代码，用于将图像作为用户输入

<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);

if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
}

if (file_exists($target_file)) {
    echo "Sorry, file already exists.";
    $uploadOk = 0;
}

if ($_FILES["fileToUpload"]["size"] > 500000) {
    echo "Sorry, your file is too large.";
    $uploadOk = 0;
}

if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
    echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
    $uploadOk = 0;
}

if ($uploadOk == 0) {
    echo "Sorry, your file was not uploaded.";

} else {
    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
        echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}
?>

但我这次的主要目的是上传

Pdf&Docx

作为用户输入，而不是图像

我试图改变，但没有成功。任何链接或至少一个带有几个链接的描述，我可以假设其余的都对我有效（我希望它是重复的，但问的方式与我猜想的不一样）。

基本上，我只是将所有

$imagefileType

更改为

$fileType

，它就有效了！！我只是跳过了图像检查，如下面的注释部分所示。甚至不确定pdf/doc和docx是否需要它，这与图像不同。如果有人提供我跳过的其他信息，或者通过@bxN5@Ravinder Reddy这种方式已经很好了，我将不胜感激

就这么简单

<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$fileType = pathinfo($target_file,PATHINFO_EXTENSION);
/*
if(isset($_POST["submit"])) {
    $check = getfilesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
}
*/
if (file_exists($target_file)) {
    echo "Sorry, file already exists.";
    $uploadOk = 0;
}
if ($_FILES["fileToUpload"]["size"] > 500000) {
    echo "Sorry, your file is too large.";
    $uploadOk = 0;
}
if($fileType != "pdf" && $fileType != "doc" && $fileType != "docx") {
    echo "Sorry, only PDF, DOC & DOCX files are allowed.";
    $uploadOk = 0;
}
if ($uploadOk == 0) {
    echo "Sorry, your file was not uploaded.";
} else {
    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
        echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}
?>

更改检查文件格式的条件/etension@RavinderReddy需要更改的内容很多，您可以指定以下内容（例如将“$imageFileType”更改为“$fileType”）等等。我不知道语言本身，也找不到合适的术语或API。请检查此链接tx buddy，我正在查看。显示错误或您尝试的内容
