利用PHP将图片转换成base64编码的实现方法

<?php
$img = &#39;test.jpg&#39;;
$base64_img = base64EncodeImage($img);
  
echo &#39;<img src="&#39; . $base64_img . &#39;" />&#39;;
  
function base64EncodeImage ($image_file) {
  $base64_image = &#39;&#39;;
  $image_info = getimagesize($image_file);
  $image_data = fread(fopen($image_file, &#39;r&#39;), filesize($image_file));
  $base64_image = &#39;data:&#39; . $image_info[&#39;mime&#39;] . &#39;;base64,&#39; . chunk_split(base64_encode($image_data));
  return $base64_image;
}
?>
