fm_get_variable
mixed fm_get_variable ( string $name )
Parameters
name (required)
The name of the variable to get.
Return
Returns the value if the variable exists, otherwise NULL. Keep in mind that there’s a difference between an empty string ‘’ and NULL. It’s perfectly legitimate for a variable to exist and the value to be empty. You can use fm_isset to determine whether or not a variable exists.
Errors
