我在archlinux上使用lampp(最新版本)我从w3c-school学习php,我在页面上传文件,在这里我的脚本无法上传任何东西唯一返回给我的是无效文件(.jpg .png ecc ..) 这里是代码:
<?php
include "config_db.php";
$name = "/upload/" . $_FILES['file']['name'];
$allowedExts = array("jpg", "jpeg", "gif", "png");
$extension = in_array(explode(".", $_FILES["file"]["name"]), $allowedExts);
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/png")
|| ($_FILES["file"]["type"] == "image/pjpeg"))
&& ($_FILES["file"]["size"] < 100000)
&& in_array($extension, $allowedExts))
{
if ($_FILES["file"]["error"] > 0)
{
echo "Return Code: " . $_FILES["file"]["error"] . "<br>";
}
else
{
echo "Upload: " . $_FILES["file"]["name"] . "<br>";
echo "Type: " . $_FILES["file"]["type"] . "<br>";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br>";
if (file_exists("upload/" . $_FILES["file"]["name"]))
{
echo $_FILES["file"]["name"] . " already exists. ";
}
else
{
move_uploaded_file($_FILES["file"]["tmp_name"],
"upload/" . $_FILES["file"]["name"]);
echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
echo '<img src="upload/' . $_FILES["file"]["name"] . '">';
}
}
}
else
{
echo "Invalid file";
}
?>
