fm_get_variable

mixed fm_get_variable ( string $name )

Description

Allows you to get the value of a variable that's been stored using fm_set_variable.

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.
