php5.3 php5.4 install and config on windows VC6 and VC9SenarioYii2 框架开始要求 PHP 版本在 PHP 5.4.0 之上
eg. yii2 中用到这样的代码 php 5.3.5 就不支持
$extension = ['name' => $package->getName(),'version' => $package->getVersion(),];
Download & Install PHP5.4 for Windowswindow php-5.4.0 之后不再支持 VC6 的编译包, 只下载到了 VC9 的编译包。
php5.4 [VC9] 在 VC6 环境中安装win下的apache是用VC6编译的，其插件(apache module)也必须用VC6编译。PHP5.4为什么不支持VC6？因为VC6太旧了，1998年的工具..不能用是指php以apache mod的方式不能用。现在php都以fast-cgi的方式挂载支持apache，连微软iis都放弃isapi转采用fast-cgi了。在不同的进程下，VC9的php fast-cgi通过进程间通讯支持apache，即使apache不是vc不是win版都没问题。去下载apache的mod_fcgid，然后把php配置到fcgid上。就可以用了

当然，之前有些老的项目在 PHP5.4 之下支持也不是很好，比如 split 函数在 5.4 中就不支持。
