php source code to convert images into data/base64 data stream

Here we share a method to convert images to base64 encoding format:

<&#63;php
$img = 'test.jpg';
$base64_img = base64EncodeImage($img);
 
echo '<img src="' . $base64_img . '" />';
/* 作者：http://www.manongjc.com */
function base64EncodeImage ($image_file) {
  $base64_image = '';
  $image_info = getimagesize($image_file);
  $image_data = fread(fopen($image_file, 'r'), filesize($image_file));
  $base64_image = 'data:' . $image_info['mime'] . ';base64,' . chunk_split(base64_encode($image_data));
  return $base64_image;
}
&#63;>

The base64 encoded string converted 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 accessing images.
