There is a mistake in your glob pattern (in the if). You are missing a *:
您的 glob 模式中有错误（在 if 中）。您缺少一个 *：
glob($directory . '*.jpg')
should work
应该管用

Minimalization approach:
最小化方法：
function getImagesNo($path)
{
return ($files=glob($path.'*.jpg')) ? count($files) : 0;
}

glob is case sensitive, according to the PHP docs. Are your extensions lowercase? Does the executing account have access to /var/www/ajaxform/?
根据 PHP 文档，glob 区分大小写。你的扩展名是小写的吗？执行帐户是否可以访问 /var/www/ajaxform/？

Just try this--
试试这个——
if (glob($directory . "*.jpg") != false)
$filecount = count(glob($directory . "*.jpg"));
else
$filecount = 0;
