Example 1: php upload file
<?php
if(isset($_FILES['image'])){
$errors= array();
$file_name = $_FILES['image']['name'];
$file_size =$_FILES['image']['size'];
$file_tmp =$_FILES['image']['tmp_name'];
$file_type=$_FILES['image']['type'];
$file_ext=strtolower(end(explode('.',$_FILES['image']['name'])));
$extensions= array("jpeg","jpg","png");
if(in_array($file_ext,$extensions)=== false){
$errors[]="extension not allowed, please choose a JPEG or PNG file.";
}
if($file_size > 2097152){
$errors[]='File size must be excately 2 MB';
}
if(empty($errors)==true){
move_uploaded_file($file_tmp,"images/".$file_name);
echo "Success";
}else{
print_r($errors);
}
}
?>
Example 2: basic code for file upload in php
//This is the minimal code for an image upload for first time learners
//html portion
<!DOCTYPE html>
<html>
<head>
<title>ImageUpload</title>
</head>
<body>
<form action="upload.php" method="post" enctype="multipart/form-data">

<input type="text" name="username">
<br>
<label>UploadImage</label>
<input type="file" name='myfile'>
<br/>
<input type="submit" value="upload">
</form>
</body>
</html>
//php portion
<?php
$user=$_POST['username'];
$image=$_FILES['myfile'];
echo "Hello $user <br/>";
echo "File Name<b>::</b> ".$image['name'];
move_uploaded_file($image['tmp_name'],"photos/".$image['name']);
//here the "photos" folder is in same folder as the upload.php,
//otherwise complete url has to be mentioned
?>
Example 3: upload file to the server php database
<?php
if(isset($_POST['btn-upload']))
{
$file = rand(1000,100000)."-".$_FILES['file']['name'];
$file_loc = $_FILES['file']['tmp_name'];
$file_size = $_FILES['file']['size'];
$file_type = $_FILES['file']['type'];
$folder="uploads/";
move_uploaded_file($file_loc,$folder.$file);
$sql="INSERT INTO tbl_uploads(file,type,size) VALUES('$file','$file_type','$file_size')";
mysql_query($sql);
}
?>
Example 4: php upload
// To change: FILENAME, array with allowed extensions, Max Filesite, Filepath
if(upload("FILENAME", array("jpeg","jpg","png"), 209715, "C:/xampp/htdocs/")){
echo "Success";
}
function upload($f_name, $f_ext_allowed, $f_maxsize, $f_path){
$f_name_2 = $_FILES[$f_name]['name'];
$f_size = $_FILES[$f_name]['size'];
$f_tmp = $_FILES[$f_name]['tmp_name'];
$f_error = $_FILES[$f_name]['error'];
$f_ext = strtolower(end(explode('.',$f_name_2)));
$f_rename = $_SESSION['uid'] . "." . $f_ext;
if($f_error == 0 && in_array($f_ext, $f_ext_allowed)
&& $f_size < $f_maxsize && mb_strlen($f_name_2, "UTF-8") < 225
&& preg_match("`^[-0-9A-Z_\.]+$`i", $f_name_2)){
if(move_uploaded_file($f_tmp, $f_path . $f_name_2){
return true;
}else{
return false;
