You should install the php7.x-cli (where x is the minor version of PHP) package to be able to execute a PHP script on a command line.

Careful, in most distro, particularly in Debian/Ubuntu, the configuration file of PHP, php.ini, is not the same for PHP-FPM or Apache, and for the command line version of PHP. So don't forget to configure same important parameters in these two php.ini, and to activate same php extensions. For example, in Debian, these two files are /etc/php/php8.2/fpm/php.ini and /etc/php/php8.2/cli/php.ini.

Note that for Debian and Ubuntu, extensions configurations are shared between fpm and cli, in a conf.d directory.

The MAMP software provides PHP-Cli. Perhaps there is also an other PHP-CLI already installed un MacOS. And then, the problem is that PHP-CLI for MAMP is not configured to access to the MAMP mysql.

The solution:

• open the file .profile stored into your home directory (/Users/your_login/)
• Modify the line where the PATH variable is defined, or add it. The goal is to add some path in this variable: /Applications/MAMP/Library/bin:/Applications/MAMP/bin/php$VERSIONPHP/bin Replace in this example $VERSIONPHP bye the version of PHP. The line should look like to this:

export PATH=/Applications/MAMP/Library/bin:/Applications/MAMP/bin/php5.6/bin:$PATH

If it was already exist, some other paths were probably defined, keep them. In all case, the $PATH should be at the end.

Depending of the package you use (WAMP or others), your php.exe may not found its php.ini file. The CLI version of php and the apache version of PHP do not share the same php.ini file. So you should create it for php.exe and/or configure it to activate same extensions as the apache php. Else you could have some errors like "unknow mysql_connect function" or "unable to connect to localhost" etc.

You have also to add the path to the php-cli binary in the PATH variable of your system.

• right click on the icon of computer, then choose properties
• In the system properties dialog, click on the tab "advanced", then on the button to see the environment variables.
• In "system variable", click on the PATH variable
• Change the value of the PATH variable, by adding the path to the directory of the binary of php.exe. For example, add c:\wamp\bin\php\php5.6.5\. Don't forget to add a ";" to separate all paths.
• validate and close the dialog
• reboot

Then you can call php.exe from any directory, and from the jelix-scripts directory.

To use jelix-scripts on a shared hosting, your hosting provider should allow you to access the server with a SSH access.

Then you have to check two things:

• check the PHP version you have in the command line: php --version. You may have to setup the right version into the manager provided by your provider.
• sometimes, some superglobals variables are not set correctly. $_SERVER['SCRIPT_NAME'] may be missing. You then have to set some variables from the command line: export SCRIPT_NAME=dev.php.

Read the documentation of your hosting provider.

You should always call dev.php with a "jelix command" name, and optionally some options and/or parameters.

First, you access help on all available commands with the help command:

   php dev.php help

Use the list command to see the list of all available commands.

   php dev.php list

This is an option available for all commands. It allows you to display all details about what the command did during its execution.

By default, a command displays nothing except errors. If you want to display details each time you launch a command, you can modify the configuration of jelix-scripts with the parameter verboseMode=true. See below.
