Install php later in Centos

Install php later in Centos

The built-in php version of Centos is very low. If we need to use a later version of php, we do not need to compile and install it. Directly Using yum for installation will save a lot of time and effort.

Introduction

PHP (Hypertext Preprocessor) is a common open source scripting language. The syntax absorbs the features of C, Java, and Perl, which is easy to learn and widely used and mainly applies to the Web development field. PHP's unique syntax is a mix of C, Java, Perl, and PHP's own syntax.

Compared with other programming languages, PHP embeds programs into HTML (an application under the standard General Markup Language) documents for execution, the execution efficiency is much higher than the CGI that completely generates the HTML Tag. PHP can also execute the compiled code to encrypt and optimize code execution, so that the code runs faster.

Install1. Check whether php is currently installed.

 rpm -qa|grep php

If you have installed PHP, delete these installation packages first:

 yum remove php*

2. Install the php Source

Install the php source in Centos 5:

  rpm -ivh http://mirror.webtatic.com/yum/el5/latest.rpm

Install the php source in CentOs 6:

  rpm -ivh http://mirror.webtatic.com/yum/el6/latest.rpm
