<?php

$g = stream_context_create(array('ssl' => array("capture_peer_cert_chain" => true)));

$r = stream_socket_client("ssl://$domain:443", $errno, $errstr, 30, STREAM_CLIENT_CONNECT, $g);

$cont = stream_context_get_params($r);

foreach($cont["options"]["ssl"]["peer_certificate_chain"] as $key => $val){
	//使用openssl扩展解析证书
	$cerInfo = openssl_x509_parse($val);

	if(strpos($cerInfo['name'], $domain)){
		echo "start:".date('Y-m-d', $cerInfo['validFrom_time_t'])."<br>";
		echo "end:".date('Y-m-d', $cerInfo['validTo_time_t']);
