No, not without writing code to do the mapping. This array mixes integer
and string keys which PHP allows but causes confusion. Reformatting gives
$_premises = array(
'APARTMENTS' => 'APARTMENT',
'APT',
'APTS' => 'APT',
'ROOMS' => 'RM',
'RMS',
'RM',
'#' => 'APT#',
'APT #',
'SUITE#',
'SUITE #',
'OFFICE#',
'OFFICE #',
'Suite',
);
The cases without a => will receive integer keys starting from zero.
0 => 'APT',
1 => 'RMS',
etc.
Likely it's used to validate/map a premise to a normalized form like this:
if (!in_array($premise, $_premises)) { // valid premise?
if (isset($_premises[$premise]) { // no, maps to a valid
premise?
$premis = $_premises[$premise]; // yes, map it
}
else {
throw new InvalidArgumentException("Premise $premise is
invalid");
}
}
// $premise is valid...
Cheers!
