PHP allows you to upload images in the directory of a website on a server. We divide this task in two steps:

Create HTML Form
PHP code for file upload

1. Create HTML Form

Here, we create a file named `index.php` that shows the image upload form.

index.php

<!DOCTYPE html>
<html>
<head>
  <title>Image Upload using PHP</title>
</head>
<body>
<form action="fileUpload.php" method="post" enctype="multipart/form-data">
   Select Image:
   <input type="file" name="image" />
   <input type="submit" name="submit" value="Upload" />
</form>
</body>
</html>

To upload an image, we must add the `enctype="multipart/form-data"` attributes in form tag. This form will be submitted to `fileUpload.php`.

2. PHP code for file upload

Now, we write PHP code to upload images in `fileUpload.php`.

fileUpload.php

<?php
if(isset($_POST["submit"])){

	$uploadDir = "../uploads/";

	$uploadPath = $uploadDir . basename($_FILES["image"]["name"]);

	$extensionsArr = ['jpeg','jpg','png'];

	$fileName = $_FILES['image']['name'];
	$fileSize = $_FILES['image']['size'];
	$fileTmpName  = $_FILES['image']['tmp_name'];
	$fileType = $_FILES['image']['type'];

	$fileExtension = pathinfo($uploadPath,PATHINFO_EXTENSION);

	if (in_array($fileExtension,$extensionsArr)) {

		$uploadImage = move_uploaded_file($fileTmpName, $uploadPath);
		if($uploadImage){
			$error = "Image uploaded successfully.";
		} else {
			$error = "There was some error in image uploading.";
		}
	}
	else{
		$error = "This file extension not allowed.";
	}
	echo $error;
}
?>

That’s it for today.
