Copy the php. ini file after installing PHP.

Direct

# Find/-name "php. ini"

Cannot be found because the configuration file is not copied during PHP installation.

After the PHP version changes, the INI file name will change.

PHP. ini-ProductionCorresponding to PhP. ini-recommended

PHP. ini-developmentCorresponding to PhP. ini-Dist

 

What are the differences between them?

Due to version updates, these files have a new name:
PHP. ini-production corresponds to PhP. ini-recommended
PHP. ini-development corresponds to PhP. ini-Dist

You usually need to rename PHP. ini-Dist or PHP. ini-recommended to PhP. ini.

The difference between the two is that PHP. ini-Dist is suitable for development programs (for testing ),

PHP. ini-recommended has a high security setting, which is suitable for product launch.

I usually change PHP. ini-recommended or the new PHP. ini-production to PhP. ini to ensure that the test environment (local) is consistent with the formal environment (online.

You need to go back to the PHP installation directory

# Cp PHP. ini-recommended/usr/local/PHP/lib/PHP. ini

Or

# Cp PHP. ini-production/usr/local/PHP/lib/PHP. ini
