PHP7 has been released for some time, it is said that there are some better improvements, The official also said faster than php5.6 twice times faster performance, and also released from the php5.x to PHP7 migration, so the future after the PHP site migration can significantly improve the performance of the site, so in order to try I also installed in the computer local PHP7.0 version.
The computer is installed locally Wamp integration package, PHP is still in the 5.2 version; I went directly to Wamp's official website to download the latest WAMP integrated installation package, but the installation httpd prompted the lack of Vcruntime140.dll, multi-party query attempts, finally found a solution.
Running the latest version of Apache and PHP7 under Windows requires Visual C++redistributable 2015, which is not as high as it used to be, and is a necessary component of the C + + application built by Visual Studio 2015. Installation once can solve the environmental problems, then go to Microsoft website Download installation program, install a restart computer can.
