How can the PHP CLI configuration differ from the PHP configuration used by a web server like Apache, and what impact does this have on extension availability?
The PHP CLI configuration can differ from the PHP configuration used by a web server like Apache due to separate php.ini files being used for each environment. This can lead to differences in extension availability between the two environments, causing certain extensions to be enabled in one environment but not the other. To ensure consistent extension availability, you can manually enable or disable extensions in the php.ini files for both the CLI and web server environments.
// To enable or disable extensions in the PHP CLI configuration, you can edit the php.ini file used by the CLI.
// Locate the php.ini file used by the CLI (you can run `php --ini` in the command line to find the location).
// Open the php.ini file in a text editor and search for the extension you want to enable or disable.
// Uncomment the extension by removing the semicolon (;) at the beginning of the line to enable it, or add a semicolon to disable it.
// Save the php.ini file and restart the PHP CLI for the changes to take effect.
// Example: Enabling the mysqli extension in the PHP CLI configuration
// Locate the php.ini file used by the CLI
// Open the php.ini file and search for "extension=mysqli"
// Uncomment the line by removing the semicolon (;) at the beginning
// Save the php.ini file and restart the PHP CLI
