snoopy picture PHP based on Snoopy almost perfectly obtains the website encoding code

First, download Snoopy.class.php online.
Calling method:

Copy code The code is as follows:

require 'lib/Snoopy.class.php';
require 'lib/WebCrawl' .class.php';//Contains the following code
$go=new WebCrawl('http://www.baidu.com');
echo $go->getCharset();
?>

Copy the code The code is as follows:

The above has introduced snoopy pictures. PHP based on Snoopy is almost perfect for obtaining website encoding code, including the content of snoopy pictures. I hope it will be helpful to friends who are interested in PHP tutorials.
