Are there any specific considerations to keep in mind when trying to detect the Safari browser using PHP?

When detecting the Safari browser using PHP, it's important to note that Safari may not always send a specific user agent string that uniquely identifies it. Therefore, it's recommended to check for common Safari user agent strings and also consider checking for specific features or behaviors that are unique to Safari.

<?php
$user_agent = $_SERVER['HTTP_USER_AGENT'];

if (strpos($user_agent, 'Safari') !== false && strpos($user_agent, 'Chrome') === false) {
    echo 'This is Safari browser';
} else {
    echo 'This is not Safari browser';
}
?>
