difference between uploading image to database and to file php code example

Example 1: how to upload image in php and store in database and folder

// Get the name of images
  	$Get_image_name = $_FILES['image']['name'];
  	
  	// image Path
  	$image_Path = "images/".basename($Get_image_name);

  	$sql = "INSERT INTO student_table (imagename, contact) VALUES ('$Get_image_name', 'USA')";
  	
	// Run SQL query
  	mysqli_query($conn, $sql);

  	if (move_uploaded_file($_FILES['image']['tmp_name'], $image_Path)) {
  		echo "Your Image uploaded successfully";
  	}else{
  		echo  "Not Insert Image";
  	}
  }

Example 2: how to place the path of an uploaded image in a database on an html file input

<?php
include("config.php");

if(isset($_POST['but_upload'])){
 
  $name = $_FILES['file']['name'];
  $target_dir = "upload/";
  $target_file = $target_dir . basename($_FILES["file"]["name"]);

  // Select file type
  $imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));

  // Valid file extensions
  $extensions_arr = array("jpg","jpeg","png","gif");

  // Check extension
  if( in_array($imageFileType,$extensions_arr) ){
 
    // Convert to base64 
    $image_base64 = base64_encode(file_get_contents($_FILES['file']['tmp_name']) );
    $image = 'data:image/'.$imageFileType.';base64,'.$image_base64;
    // Insert record
    $query = "insert into images(image) values('".$image."')";
    mysqli_query($con,$query);
  
    // Upload file
    move_uploaded_file($_FILES['file']['tmp_name'],$target_dir.$name);
  }
 
}
?>

<form method="post" action="" enctype='multipart/form-data'>
