Strip whitespaces from array items

Anatomy

<array:trim var="var" var_result="(destructive on 'var')" type="both" key="string"/>

Description: ARRAY:TRIM strips whitespace characters from the beginning and/or end of the value of each item of an array.

A given key may specify the column of a multidimensional array to trim. If however, the key is omitted, then the array is treated as an unidimensional list.

Attention:

If a key is specified and that key does not exist within the inner array, the corresponding item of the outer array will be skipped.

ARRAY:TRIM 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. It preserves the key and value associations of the array.
