PHP Uploading File

For build an upload application, you need two files. One for upload interface, and one another for processing the file. Firstly, make upload.html:

<form action="temp3.php" method="post" enctype="multipart/form-data">

File: <input type="file" name="file"/>

<input type="submit" value="Upload"/>

</form>

Then make your php file for processing the file:

<?php

if(move_uploaded_file($_FILES["file"]["tmp_name"],

    "./".$_FILES["file"]["name"])){   // save in same folder

    echo "Success Upload";

}else{

    echo "Fail For Upload";

}

?>

With two files above, you must have upload application.

To get the file name, use:

echo $_FILES["file"]["name"];

To get the file size, use:

echo $_FILES["file"]["size"];    // in bytes. divide by 1024 

                                 // to get kB

To get the file type, use:

echo $_FILES["file"]["type"];

To get the the error code, use:
echo $_FILES["file"]["error"];     // if 0, it is success

To get just some specified file type, use:

if(($_FILES["file"]["type"] == "image/gif") || 

   ($_FILES["file"]["type"]=="image/jpg") || 

   ($_FILES["file"]["type"]=="image/jpeg"))

{

    // process file

}else{

    echo "Upload Failed";

}


To limit the size, for example just for 2 kB, use:

if ($_FILES['file"]["size"] < 2000) {

    // process files

}else{

    echo "Failed to upload";

}

To place the file in the same folder of upload.php, use:

$target = "./".$_FILES["file"]["name"];

To place it in the root of file system, use:

$target = "/".$_FILES["file"]["name"];

To pace it in the upload folder that same level to htdocs (assume upload.php in htdocs), use:
$target = "../upload/".$_FILES["file"]["name"];
