Are there best practices for implementing target="_blank" in PHP code?

When using target="_blank" in PHP code to open links in a new tab, it is important to ensure that the attribute is properly sanitized to prevent potential security vulnerabilities such as cross-site scripting attacks. One common approach is to use htmlspecialchars() function to encode the attribute value before outputting it in the HTML. 

<?php
$link = "https://example.com";
$sanitizedLink = htmlspecialchars($link, ENT_QUOTES, 'UTF-8');
echo "<a href='$sanitizedLink' target='_blank'>Link</a>";
?>
