|

|
|
Validate all passed values are true or false. Abort catalog compilation if the
|
||
|
|
value does not pass the check.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
These booleans validate
|
||
|
|
|
||
|
|
$iamtrue = true
|
||
|
|
validate_bool(true)
|
||
|
|
validate_bool(true, true, false, $iamtrue)
|
||
|
|
|
||
|
|
These strings do NOT validate and will abort catalog compilation
|
||
|
|
|
||
|
|
$some_array = [ true ]
|
||
|
|
validate_bool("false")
|
||
|
|
validate_bool("true")
|
||
|
|
validate_bool($some_array)
