PHP File Uploading

PHP File Uploading :

The “enctype” attribute of the <form> tag specifies which content-type to use when submitting the form.” Multipart/form-data” is used when a form requires binary data, like the contents of a file , to be uploaded.
The <input type=”file” name=”t3”> tag specifies that the input should be processed as a file.default value of “enctype” attribute of <form> tag is “application/x-www-form-urlencoded”.
    <body style="background-image: url(Photo0104.jpg); color:white">
        <h1 align="center">submit form</h1><br><br>
        <form action="uploadtest.php" method="post" enctype="multipart/form-data">
            <table style="font-family: verdana; font-size: 20px;width: 50%">
                <tr height="50">
                        <input type="text" name="t1" size="30">
                <tr height="50">
                    <td><input type="file" name="t2" size="30"></td>
                <tr height="50">
                    <td colspan="2" align="center">
                        <input type="submit" value="register">
$_FILES is a built-in global array of php which stores all the attached file details and is a multi-dimentional array. The first parameter is the form’s input name and the second index can be either “name”,”type”,”size”,”temp-name” or “error”.
$_FILES[‘t3’][‘name’] – the name of the uploaded file.
$_FILES[‘t3’][‘type’] – type of the uploaded file.
$_FILES[‘t3’][‘size’] – size in bytes.
$_FILES[‘t3][‘temp-name’] – the name of the temporary copy of the file stored on the server.
$_FILES[‘t3’][‘error’] – the error code resulting from the file upload. If the value is 0 means no errors in uploading.
