Flip array

Anatomy

<array:flip var="var" var_result="(destructive on 'var')"/>

Description: ARRAY:FLIP exchanges all keys in an array with their associated values.

Attention:

ARRAY:FLIP is destructive, in the sense that it modifies the array in-place, unless 'var_result' is specified in which case a copy of the resulting array will be stored in 'var_result' instead. A distinct array with string-recasted values as keys will be created. If a value has several occurrences within the array, only the last key will be used while all other items with that particular key will be discarded.
