Language performance optimization for PHP performance: Install VLD extension--detect performance

Installing with Linux commands

When I installed, always prompt no Configuer file, check the Readme file, the original can be installed through Git, the following is the GIT installation.

Don't end it, activate the VLD extension in the php.ini file.

Each is explained at the time of the command installation.

Php-dvld.active =1–dvld.execute=0 test.php

VLD extension of the main two parameter list
