How to use php to display images in base64

The example in this article describes the method of displaying images in base64 in PHP. Share it with everyone for your reference, the details are as follows:

Here, the image is saved to the web page in the form of a string, so that there is no need to load the image again.

This is the Data URI scheme defined in RFC2397. The purpose is to embed some small data directly into the web page, so that there is no need to load it from an external file. For example, the string of characters above is actually a picture. Picture, copy and paste these characters into Firefox's address bar and go to it, you can see it.

In the above Data URI, data represents the protocol name for obtaining data, image/jpeg is the data type name, base64 is the encoding method of the data, and what follows the comma is the base64-encoded data of the image/jpeg file.

The currently supported types of Data URI scheme are:

data:text/plain, text data
data:text/html, HTML code
data:text/html;base64 ,base64 encoded HTML code
data:text/css,CSS code
data:text/css;base64,base64 encoded CSS code
data:text/javascript,javascript code
data:text /javascript;base64,base64 encoded Javascript code
data:image/gif;base64,base64 encoded gif image data
data:image/png;base64,base64 encoded png image data
data:image /jpeg;base64,base64-encoded jpeg image data
data:image/x-icon;base64,base64-encoded icon image data

php code is as follows:

$img_file = 'https://img.alicdn.com/bao/uploaded/TB1eaiELpXXXXcPXpXXSutbFXXX.jpg';
$img_info = getimagesize($img_file);
$img_src = "data:{$img_info['mime']};base64," . base64_encode(file_get_contents($img_file));
exit("<img src=&#39;{$img_src}&#39; />");
