我同意最佳答案，但也想补充一点。我使用ANT脚本从GIT存储库中剥离和修改文件，因此我确定不会覆盖任何生产文件。ANT中有一个不错的选项来修改Java属性文件。这意味着将您的本地测试变量放在java样式的属性文件中，并添加一些代码来处理它，但这使您有机会在在线FTP站点之前自动构建站点。通常，您会将生产信息放在site.default.properties文件中，然后让ANT管理设置。您的本地设置将位于site.local.properties中。

然后使用它：

$props->readFile($_SERVER["DOCUMENT_ROOT"] . "/lib/site.default.properties",$_SERVER["DOCUMENT_ROOT"] . "/lib/site.local.properties");
#create one DEFINE
$props->createDefineFromProperty("picture-path");
# create a number of DEFINEs for enabled modules
$modules = $props->createDefinesFromProperties("mod_enabled_");
您的site.default.properties如下所示：
release-date=x
environment=PROD
picture-path=/images/
SITE_VERSION_PRODUCTION=PROD
SITE_VERSION_TEST=TEST
SITE_VERSION_DEVELOP=DEV
# Available Modules
mod_enabled_x=false
mod_enabled_y=true
mod_enabled_z=true
您的site.local.properties如下所示（注意不同的环境和启用的模块）：
release-date=x
environment=TEST
picture-path=/images/
SITE_VERSION_PRODUCTION=PROD
SITE_VERSION_TEST=TEST
SITE_VERSION_DEVELOP=DEV
# Available Modules
mod_enabled_x=true
mod_enabled_y=true
mod_enabled_z=true
以及您的ANT指令：（$ d {deploy}是您的部署目标目录）

file="${deploy}/lib/site.properties"
comment="Site properties">
<entry key="environment" value="PROD"/>
<entry key="release-date" type="date" value="now" pattern="yyyyMMddHHmm"/>
