Key error reporting during wampserver installation of multiple php versions

Wampserver installation of multiple php versions error-key problem recently I like to use wampserver to build a local php running environment. it is mainly a one-click installation. it is always used before appserv is also quite useful after wamp is used wamp is better than duang.

By default, the php version in the downloaded wamp is 5.3.0. Later, due to work requirements, you need to switch to a version earlier than php5.3.0, for example, installing zend optimizer. at first, you downloaded a php 5.2.17 installation package, making it hard to install the package. accessing the apache error access log shows this. I believe most users have encountered this problem.

Baidu checked these problems. the solution on the internet is to modify port 80 and httpd. conf modify php. anyway, there is no way to solve the problem because of the various methods. later, I accidentally browsed a blog post to know that apache does not support ISAPI in the win32 bit system to run the TS version. php and wamp and other environments use ISAPI to run php by default. Therefore, zend optimizer cannot be installed in the php5.2.17 environment of the TS version.

Method 1 download the php5.2.17 installation method of TS under win32. Baidu can also refer to this article.

Method 2 modify the default php running mode under win32 to Fast CGI. refer to this article.
