This is used to set a default value for a variable. If the variable is unset or an empty string, the given default value is printed instead. Default takes the one argument.
Note: With error_reporting(E_ALL), undeclared variables will always throw an error within the template. This function is useful for replacing null or zero length strings.
Parameter Position | Type | Required | Default | Description |
---|---|---|---|---|
1 | string | No | empty | This is the default value to output if the variable is empty. |
