All that is really needed is a preserve_key to be added to
array_splice function and you pretty much have it ...

Oh well. I think I'll have to create a map and use that to keep the
array in order:
$set = array( 'vegetable'=>'tomato', 'fruit'=>'tomato',
'bean'=>'chickpea', 'grain'=>'corn' );
$map = array_keys( $set );
$map['bean'] = 'legume';
$set['legume'] = $set['bean'];
unset( $set['bean'] );
foreach ( $map AS $orig_key=>$key ) {
print $set[ $key ]."<br>";
}
I don't think the -- $map['bean'] = 'legume'; -- part is doing what
you expect. It would have to be $map[2] = 'legume' intead.
Are you using php5? There's an array_combine() function... you
could do this:
$array = array('vegetable'=>'tomato', 'fruit'=>'tomato',
'bean'=>'chickpea', 'grain'=>'corn');
$keys = array_keys($array);
$values = array_values($array);
$keys[2] = 'legume';
$array = array_combine($keys, $values);
print_r($array);
That avoids a foreach loop. I am a little surprised php doesn't
seem to provide a function for swapping a key name in place.
