How to change php version number in linux

How to change the PHP version number in Linux: First use the "find" command to find the location of each PHP version; then use the "ln" command to create a soft link containing the path to the new PHP version; finally use the "export" command Just add the soft link to the PATH path.

The operating environment of this article: centos7 system, PHP5.4&&PHP5.5 version, thinkpad t480 computer

Operation steps:

1. Use the find command to find where php is.

#find / -name php

2. The ln command (a lot of resources on Baidu) is mainly used to create soft connections

Now I mainly want to change the 5.4 version to the 5.5 version:

#ln -s /usr/local/php-5.5/bin/php(你想要换成的php版本的路径) /usr/sbin/php（最后一个php可以换成你自己喜欢的名字，最好php吧）

3. The export command will add the soft connection to the PATH path

#export PATH="$PATH:/usr/sbin/php"

Add the connection you prepared above That’s it, don’t miss the colon in the middle, it’s used for segmentation

Finally, look at the effect

#php -v
