无法加载PHP扩展

Question

我在Windows 2008服务器上使用Apache2.4和php7。

在php.ini中启用了一些扩展

如果运行php -m，则可以看到它们已安装

但是当我将此代码放入apache / htdocs下的.php文件并通过localhost / aaa.php访问它时

<?php
print_r(get_loaded_extensions());
?>

未显示启用的扩展名，输出为

Array ( [0] => Core 
        [1] => bcmath 
        [2] => calendar 
        [3] => ctype 
        [4] => date 
        [5] => filter 
        [6] => hash 
        [7] => iconv 
        [8] => json 
        [9] => SPL 
        [10] => pcre 
        [11] => readline 
        [12] => Reflection 
        [13] => session 
        [14] => standard 
        [15] => mysqlnd 
        [16] => tokenizer 
        [17] => zip 
        [18] => zlib 
        [19] => libxml 
        [20] => dom 
        [21] => PDO 
        [22] => Phar 
        [23] => SimpleXML 
        [24] => xml 
        [25] => wddx 
        [26] => xmlreader 
        [27] => xmlwriter 
        [28] => apache2handler 
    )

如果我将其放入a.php并通过localhost访问它，我还可以看到未安装GD。

<?php if ( extension_loaded( 'gd' ) ): ?>
                    <li class="success">GD extension loaded.</li>
<?php else: $success = FALSE; ?>
                    <li class="fail">You do not have the GD PHP extension loaded.</li>
<?php endif; ?>

但是，如果我运行php.exe a.php，结果显示GD已加载。

因此，似乎通过apache服务器和本地php可执行文件运行会返回不同的结果。有人可以帮忙吗？
