            'ssl://gateway.sandbox.push.apple.com:2195', $err,
            $errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);

but $fp show blank .how to resolve

Answer 1

我知道有些晚了，但是处理$fp的响应和打印可能会为您提供更多详细信息。

if ($this->fp) {
    echo 'Successfully connected to server of APNS';

} else {
    echo "Failed to connect: $err $errstr" . PHP_EOL;
}
