We need to create the HTML Form to upload files to server. You can choose any files to upload in server using below html form.
Upload HTML Form Example :
<!DOCTYPE html>
<html>
<body>
<form action="upload.php" method="post" enctype="multipart/form-data">
Choose file to upload:
<input type="file" name="uploadfile" id="uploadfile">
<input type="submit" value="Upload File" name="submit">
</form>
</body>
</html>
Follow the below rules for above HTML form.
- Method should be post i.e method="post"
- Form attribute enctype must be mandatory. i.e enctype="multipart/form-data"
- <input> tag should have type="file" attribute.
PHP Script to upload file
move_uploaded_file() function is used to upload file in destination location in server.
Example :
File : upload.php
<?php
echo "<br/> File name : ".$filename=$_FILES['uploadfile']['name'];
echo "<br/> File size : ".$filesize=$_FILES['uploadfile']['size'];
echo "<br/> Temp File name : ".$filetempname=$_FILES['uploadfile']['tmp_name'];
// copy(source,destination); // Also you can use copy() function
