PHP source of the image into the data/base64 data stream detailed

In the development of the website, we can see some websites to convert images into Base64 data stream, the advantage of doing this is two points, one is to reduce the server HTTP request, the second is the image can be stored as a string in the database, that is, the picture can be read directly from the database, then PHP how to convert the picture to data/ What about the Base64 string? , the need for friends can refer to the next

PHP source to convert images into data/base64 data stream

Here we share a way to convert a picture to a Base64 encoded format:

<?php$img = ' test.jpg '; $base 64_img = Base64encodeimage ($img); Echo '  ';/* Author: http://www.manongjc.com */function base64encodeimage ($image _file) {  $base 64_image = ';  $image _info = getimagesize ($image _file);  $image _data = fread (fopen ($image _file, ' R '), FileSize ($image _file));  $base 64_image = ' data: '. $image _info[' MIME ']. '; Base64, '. Chunk_split (Base64_encode ($image _data));  return $base 64_image;}? >

The base64 encoded string obtained by the above method can be stored in the database and can be read directly from the database when needed, reducing the number of requests when the image is accessed.

The above is the whole content of this article, I hope that everyone's study has helped.
