An implementation method of converting pictures into base64 encoding using PHP _php instance

Let's start by asking why we're coding the picture base64.

Base64 is one of the most common encoding methods for transmitting 8Bit byte code on the current network. The main purpose of Base64 is not to encrypt, but to convert some binary numbers into ordinary characters for network transmission. Because these binary characters belong to the control characters in the transport protocol, they cannot be transmitted directly, so they need to be converted. Although the image may be transmitted directly, but we can also make it into a string directly in the source code, without requiring the browser to read the source code and then download from the server.

How to use PHP to base64 the image to decode the output

<?php
$img = ' test.jpg ';
$base 64_img = Base64encodeimage ($img);
 
Echo '  ';
 
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
}

Summarize

The base64 encoded string, which is converted from the above method, can be stored in the database and can be read directly from the database when needed, reducing the number of requests to access the picture. This method is already included in the global function Library of miniframework.
