How to interpret and replace the contents of database config.php file

We download the program on the Internet, there are many and do not install the program, but we need to manually modify the database configuration file some also need a website path such as domain name, the following by the charm of the network for everyone to explain

<?Php
$pe [' db_host '] = ' localhost '; server name
$pe [' db_name '] = ' cps1 '; database name
$pe [' db_user '] = ' root '; database user name
$pe [' db_pw '] = '; Database password
$pe [' db_coding '] = ' utf8 '; encoding
$pe [' url_model '] = ' pathinfo_safe '; security Code
$pe [' domain_cps '] = ' cps.cps.com '; site domain name here needs to change to its own local domain name debugging to local directory such as http://localhost/viicms/
$pe [' domain_mark '] = ' cps.cps.com '; watermark or whatever.

define (' Dbpre ', ' cps_ ');
?>

Local debugging I changed it so I put the program in the Viicms folder instead of the root directory and it's written like this.

<?php$pe[' db_host ' = ' localhost '; $pe [' db_name '] = ' viicms '; $pe [' db_user '] = ' root '; $pe [' db_pw '] = ' root '; $pe [' Db_ Coding '] = ' utf8 '; $pe [' url_model '] = ' pathinfo_safe '; $pe [' domain_cps '] = ' http://localhost/viicms/'; $pe [' Domain_mark '] = ' cps.cps.com ';d efine (' Dbpre ', ' cps_ ');? >
