Profile pic save option in PHP - php

Question

I have created a app in php. How i can save the profile pictures of the users? Will that be a good idea to save them in db using base64 encode, like this
<img src="data:image/jpeg;base64,/9j/4AAQSkZJRgABAQEAWgBaAAD/4gxYSUNDX1BST0ZJTEUAAQEAAAxITGlubwIQAAB..." />
or anything else

Answer 1

It's a good idea/practice usually only for very small CSS images that are going to be used together (like CSS sprites) when IE compatibility doesn't matter, and saving the request is more important than cacheability.
It has a number of notable downsides:
Doesn't work at all in IE6 and 7.
Works for resources only up to 32k in size in IE8. This is the limit
that applies after base64 encoding. In other words, no longer than
32768 characters.
It saves a request, but bloats the HTML page instead! And makes
images uncacheable. They get loaded every time the containing page or
style sheet get loaded.
Base64 encoding bloats image sizes by 33%.
If served in a gzipped resource, data: images are almost certainly
going to be a terrible strain on the server's resources! Images are
traditionally very CPU intensive to compress, with very little
reduction in size.

Answer 2

Store images in your server and store the path to images in the database. This will reduce extra overload on database server.

Answer 3

Its better to store file path in database rather storing files in databases. Datbases are for structured data, not for blobs. Moreover database storage is usually more expensive than file system storage. Servers doesn't need any special coding or processing to access images in the file system

Answer 4

Copy base64 image "src" to a textbox using javascript. Post a form with base64 url textbox. Its better to save url in database rather saving a file in database.
You can save your base64 image by using this PHP code:
<?php
define('UPLOAD_DIR', 'images/');
$base64img=$_POST['base64img'];
if (stristr($base64img, "data:image/jpeg;base64,")) {
$base64img = str_replace('data:image/jpeg;base64,', '', $base64img);
$uid=time();
$data = base64_decode($base64img);
$file = UPLOAD_DIR . $uid.'.jpg';
file_put_contents($file, $data);
}elseif (stristr($base64img, "data:image/png;base64,")) {
$base64img = str_replace('data:image/png;base64,', '', $base64img);
$uid=time();
$data = base64_decode($base64img);
$file = UPLOAD_DIR . $uid.'.png';
file_put_contents($file, $data);
}elseif (stristr($base64img, "data:image/jpg;base64,")) {
$base64img = str_replace('data:image/jpg;base64,', '', $base64img);
$uid=time();
$data = base64_decode($base64img);
$file = UPLOAD_DIR . $uid.'.jpg';
file_put_contents($file, $data);
}
?>
