1. In etc Add the configuration export PATH=$PATH:/usr/local/php/lib

under the /profile file. The content of the file is as follows:

if [ "$HISTCONTROL" = "ignorespace" ] ; then
    export HISTCONTROL=ignoreboth
else
    export HISTCONTROL=ignoredups
fi

export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE HISTCONTROL
export PATH=$PATH:/usr/local/php/lib    // 增加此段代码（php的路径）
#export PATH =/usr/local/php/bin/php

# By default, we want umask to get set. This sets it for login shell
# Current threshold for system reserved uid/gids is 200

2. After adding the path, execute the following code

source /etc/profile

source /etc/profile  //centos 7

If an error is reported:

[root@localhost html]# php -m
-bash: php: command not found

Solution:

# which php  //结果是/usr/local/php/bin/php
# ln -s /usr/local/php/bin/php /usr/bin/php

3. Test

# php -m 
# php -i
