wp_is_https_supported() – Function | Developer.WordPress.org

wp_is_https_supported(): bool

Checks whether HTTPS is supported for the server and domain.

Description

This function makes an HTTP request through wp_get_https_detection_errors() to check for HTTPS support. As this process can be resource-intensive, it should be used cautiously, especially in performance-sensitive environments, to avoid potential latency issues.

Return

bool True if HTTPS is supported, false otherwise.

Source

function wp_is_https_supported() {
	$https_detection_errors = wp_get_https_detection_errors();
