PHP extension Dio is not loaded?

Question

I am trying to communicate with the COM Ports using the DIO extension, but it's not working it seems. I have already added the .dll file into my ext folder but I still can't find the Dio support enabled in PHP info(). I have already restarted my XAMPP server more than twice, but still, it's not working. This is my current code for the com port testing.

    $portName = 'COM9:';
    $baudRate = 9600;
    $bits = 8;
    $spotBit = 1;

    header( 'Content-type: text/plain; charset=utf-8' ); 
    ?>
    Serial Port Test
    ================
<?php


function echoFlush($string)
{
    echo $string . "\n";
    flush();
    ob_flush();
}

if(!extension_loaded('dio'))
{
    echoFlush( "PHP Direct IO does not appear to be installed for more info see: http://www.php.net/manual/en/book.dio.php" );
    exit;
}

This is the error I am getting now.

PHP Direct IO does not appear to be installed for more info see: http://www.php.net/manual/en/book.dio.php

This is the steps I followed while installing the extension:

1. I downloaded the direct io from the pecl website
2. Then I copied the php_dio.dll into the PHP/ext folder
3. Next, I edited the php.ini file by adding the extension=php_dio.dll
4. Then I restarted my XAMPP webserver
5. I opened php_info() to check out the php_dio.dll and found that it is not still loaded.

Answer 1

您是否在phpinfo()输出中检查了extension_dir指令？

Answer 2

尝试使用 PHP 7.2 版，它适用于我，但不适用于 7.3 版。

We got confused with the XAMPP architecture version with Windows. It worked after installing the right. Thank you guys.
