PHP code that blocks bots from harvesting email addresses from your website

Spam is very annoying. Here is a method to automatically block robots from collecting email addresses from your website.
Copy code The code is as follows:
function security_remove_emails($content) {
$pattern = '/([a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+. [a-zA-Z]{2,4})/i';
$fix = preg_replace_callback($pattern,
"security_remove_emails_logic", $content);

return $fix;
}
function security_remove_emails_logic($result) {
return antispambot($result[1]);
}
add_filter( 'the_content', 'flex_remove_emails', 20 );
add_filter( 'widget_text', 'flex_remove_emails', 20 );

Put this in functions. In the php file, if a robot collects email addresses, it will be automatically blocked.
