Type
operator
Summary
Determines if an array has a given key
Syntax
<Needle> ( is not | is ) among the keys of <Target>
Description

tVar is among the keys of tArray
is not equivalent to
tVar is in (the keys of tArray)
as the latter IsInList operation is case sensitive.

Value
| Name | Type | Description |
|---|---|---|
