Most web servers nowadays support [PHP][] and MySQL, but if you are having trouble running PHP code, there's an outside chance your web server doesn't support it. To execute PHP scripts on your website, your web host must support PHP/MySQL. If you are unsure whether you have PHP/MySQL support with your host, you can find out by running a test that involves uploading a simple program and trying to run it.

如今，大多数Web服务器都支持[PHP][]和MySQL，但是，如果您在运行PHP代码时遇到麻烦，那么您的Web服务器可能不支持它。 要在您的网站上执行PHP脚本，您的虚拟主机必须支持PHP / MySQL。 如果不确定主机是否支持PHP / MySQL，可以通过运行测试来找出答案，该测试涉及上载简单的程序并尝试运行它。

## 测试PHP支持 **(** Testing for PHP Support **)** ##

*  Create a blank text file using [NotePad][] or any other text editor and call it **test.php**. The .php extension at the end of the file name is critically important. It cannot be .php.html or .php.txt or anything other than .php.
    
    使用[NotePad][]或任何其他文本编辑器创建一个空白文本文件，并将其命名为**test.php** 。 文件名末尾的.php扩展名至关重要。 它不能是.php.html或.php.txt或.php以外的任何其他内容。
 *  Put this PHP code in the text file:
    
    将此PHP代码放在文本文件中：
 *      <?php phpinfo() ; ?>
 *  Save the file and upload it to the root of your website on the web server using FTP. The folder may be called public\_html or web root or some other name depending on your server, but it is the main folder for your website.
    
    保存文件，然后使用FTP将其上传到Web服务器上网站的根目录。 根据您的服务器，该文件夹可能称为public\_html或Web根目录或其他名称，但这是网站的主文件夹。
 *  In a browser, go to **www.\[yoursite\].com/test.php**. If you see the code as you entered it, then your website cannot run PHP with the current host. If your server supports PHP, you will see a list of all the PHP/SQL properties that are supported by the host.
    
    在浏览器中，转到**www。\[yoursite\] .com / test.php** 。 如果您在输入代码时看到代码，则您的网站无法在当前主机上运行PHP。 如果您的服务器支持PHP，则将看到主机支持的所有PHP / SQL属性的列表。

## PHP版本 **(** PHP Versions **)** ##

Among the supported properties listed should be the version of PHP the web server is running. PHP is updated occasionally and each new version typically has better security practices and new features you can take advantage of. If you and your host are not running recent, stable, compatible PHP versions, some problems might be the result. If you are running a more recent stable version that your web server, you may need to find a new web server.

在列出的受支持属性中，应该是Web服务器正在运行PHP版本。 PHP有时会进行更新，并且每个新版本通常都具有更好的安全性做法和您可以利用的新功能。 如果您和您的主机未运行最新的，稳定的，兼容PHP版本，则可能会导致某些问题。 如果您正在运行Web服务器的最新稳定版本，则可能需要查找新的Web服务器。
