Image Upload Without Validation With Proper Explanation Using PHP Along With Coding

NOTE: To upload the Image I have created one new folder "uploads" which I have used within my code "$folder="uploads/".$fileName" within my folder "Image Upload Without Validation".

So, just let me explain here why I have used enctype="multipart/form-data" in Image Upload Without Validation.php page. Hooray, let's begin. 

Here I have used enctype="multipart/form-data" as because text can be converted into binary by default. But image or file cannot be converted into binary by default. So, to convert the image or file into binary, I have used encrypt type (enctype) here. So, what does machine understands? I know that machine understand only 0 and 1 in his language. Machine doesn't understand any other language. So, in backend when the data is passing from User Interface (UI), it will count as binary only. That's why, here I have used enctype="multipart/form-data".

Codes:

Image Upload Without Validation.php

<!DOCTYPE html>

<html>

<head>

<meta charset="utf-8">

<meta name="viewport" content="width=device-width, initial-scale=1">

<title>Image Upload Without Validation</title>

</head>

<body>

<form method="post" action="fileaction.php" enctype="multipart/form-data">

Image Upload: <input type="file" name="image"><br>

<button name="btn" type="submit">Submit</button>

</form>

</body>

</html>

Now let me explain here in fileaction.php why I have used move_uploaded_file() function. Horray, let's go.

Here in fileaction.php, I have used move_uploaded_file() function as because move_uploaded_file() function is used to move the uploaded file into new destination. Like here as I have used move_uploaded_file($tmpName,$folder) means this move_uploaded_file() function move the uploaded file from $tmpName to $folder.

fileaction.php

<?php

$fileName=$_FILES['image']['name'];

$tmpName=$_FILES['image']['tmp_name'];

$folder="uploads/".$fileName;

move_uploaded_file($tmpName, $folder);

?>

<img src="<?php echo $folder; ?>" height="400px" width="400px">
