Elenco dei parametri

function_name

The function to override.

function_args

The function arguments, as a comma separated string.

Usually you will want to pass this parameter, as well as the function_code parameter, as a single quote delimited string. The reason for using single quoted strings, is to protect the variable names from parsing, otherwise, if you use double quotes there will be a need to escape the variable names, e.g. \$your_var.

function_code

The new code for the function.

Valori restituiti

Restituisce TRUE in caso di successo, FALSE in caso di fallimento.
