Question

我尝试修改php脚本，以使其上传pdf而不是图像。我已经进行了几次修改，但没有一个工作。如果有人可以向我展示如何修改此脚本以允许上传pdf，我非常感谢。我是php的新手，需要那里的php专家提供更多指导。预先感谢您的帮助。

无论如何这是代码：

## PHP Script ##
<?php
// SOURCE + DESTINATION
$source = $_FILES["file-upload"]["tmp_name"];
$destination = __DIR__.'/../../download/'. $_FILES["file-upload"]["name"];
echo "Uploaded ";
$error = "";

// CHECK IF FILE ALREADY EXIST
if (file_exists($destination)) {
$error = $destination . " already exist.";
}

// ALLOWED FILE EXTENSIONS
if ($error == "") {
$allowed = ["application/pdf", "application/x-pdf", "application/acrobat", "applications/vnd.pdf", 
"text/pdf". "text/x-pdf"];
$ext = strtolower(pathinfo($_FILES["file-upload"]["name"], PATHINFO_EXTENSION));
if (!in_array($ext, $allowed)) {
$error = "$ext file type not allowed. File must be uploaded in PDF format. - " . $_FILES["file- 
upload"]["name"];
  }
}

// LEGIT TEXT FILE CHECK
if ($error == "") {
if (getimagesize($_FILES["file-upload"]["tmp_name"]) == false) {
$error = $_FILES["file-upload"]["name"] . " is not a valid file.";
  }
}

// FILE SIZE CHECK
if ($error == "") {
// 1,000,000 = 1MB
if ($_FILES["file-upload"]["size"] > 50000000) {
$error = $_FILES["file-upload"]["name"] . " - file size too big!";
  }
}

// ALL CHECKS OK - MOVE FILE
if ($error == "") {
if (!move_uploaded_file($source, $destination)) {
$error = "Error moving $source to $destination";
  }
}

// ERROR OCCURED OR OK?
if ($error == "") {
echo $_FILES["file-upload"]["name"] . " Upload DONE.";
} else {
echo $error;
}
?>

尝试在HTML中进行更改：

accept =“ application / pdf”

脚本无法识别文件扩展名，无法在php中上传pdf
