Solution

1. First, check how many php.ini there are on Linux. It turns out that there are two:

[[email protected] ~]#find / -name php.ini
/usr/local/php/etc/php.ini/etc/php.ini

It is roughly guessed that the php configuration file loaded by php cli is inconsistent with the configuration file loaded by phpinfo(). Use the command to see which php.ini is loaded by cli:

[[email protected] ~]#php -i | grep php.ini

The result is:

It is found that the loaded php.ini configuration file is indeed inconsistent, then search the php/bin directory and edit the /etc/profile file

[[email protected] /]#vim /etc/profile

Add an environment variable in the last line:

export PATH="/usr/local/php/bin:$PATH"

Finally save and exit and execute the following command to refresh the environment variable:

[[email protected] /]#source /etc/profile

php -v View version

Summary

It is caused by the inconsistency between the php configuration file loaded by cli and the php configuration file loaded by the web server.
