In PHP, is it possible to upload files to the server? - php

Question

In PHP, is it possible to upload files to the server? If so, then how can I create an upload form and insert the files to a specific page? Any extension images: .jpeg .gif or files: .txt .pdf etc. I am using XAMPP (localhost to view my website).
I have tried many tutorials, but there are lot of errors.
This is this HTML file:
<form action="fileupload.php" method="post" enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file" />
<br />
<input type="submit" name="submit" value="Submit" />
</form>
And here is the PHP script:
if ($_FILES["file"]["error"] > 0)
{
echo "Error: " . $_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 "Stored in: " . $_FILES["file"]["tmp_name"];
}
The result is shown like this:
Upload: (file here)
Type: image/jpeg
Size: 757.521484375 Kb
Stored in: (temp file in C:)
But whenever I find my file in the tmp folder. It's nowhere to be found.

function getExtension($str)
{
$i = strrpos($str,".");
if (!$i)
{
return "";
}
$l = strlen($str) - $i;
$ext = substr($str,$i+1,$l);
return $ext;
}
$extension = getExtension($filename);
$extension = strtolower($extension);
if($extension=="jpg" || $extension=="jpeg" || $extension=="gif" || $extension=="txt" || $extension=="pdf" ){
echo "Upload: " . $_FILES["file"]["name"] . "<br />";
echo "Type: " . $_FILES["file"]["type"] . "<br />";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
move_uploaded_file($_FILES["file"]["tmp_name"],"upload/" .date("d_m_h_i_s"). $_FILES["file"]["name"]);
}
The getExtension function helps to get the extension of the file. The files will be uploaded to the upload folder.
