Input validation

As a quick run of the script without any parameters reveals, the CLI takes three input parameters:

Syntax: 
 php import_user.php <import file> <template user> <realm id> 

The import file is the text file with the user IDs you created earlier. The template user will be your _CustomerA_user. The realm id references the ID of the Authentication Realm and can be a number between 0 and 2:

  • Realm id 0 - Local Authentication
  • Realm id 1 - LDAP Authentication
  • Realm id 2 - Web Authentication

The following code checks the entered realm id for its valid range and sets it to Local Authentication (0) if it has not been set correctly:

// Realm Id can be: 0 - Local, 1 - LDAP, 2 - Web Auth 
if ( ( $realm_id < 0 ) || ( $realm_id > 2  ) ) { 
   // The realm id will be local unless a valid id was given 
   $realm_id = 0; 
}
