Create The Upload File PHP Script

Create “upload.php” file and add the below PHP code.

<?php

$target_dir = "uploads/";

$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);

$uploadOk = 1;

$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));

if(isset($_POST["submit"])) {

$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);

if($check !== false) {

echo "File is an image - " . $check["mime"] . ".";

$uploadOk = 1;

} else {

echo "File is not an image.";

$uploadOk = 0;

}

If you want to add the condition to check the file size, then use the below code.

if ($_FILES["fileToUpload"]["size"] > 500000) {

echo "Sorry, your file is too large.";

$uploadOk = 0;

}
