Default #34526 : array-related operation to "reduce" contained items

From: soletan at toxa dot de
Operating system: Linux
PHP version: 5.0.5
PHP Bug Type: Feature/Change Request
Bug description: array-related operation to "reduce" contained items

Is it possible to have an array_***x-method to perform the transformation
on arrays as given below. Since I am working with DBs and wrapping records
of tables using classes I often
get the case to receive an array as given below and require
to pass the list of IDs, only.

For sure I can do the transformation all by myself in PHP using foreach.
But since my software is getting more and more complex I appreciate any
chance to increase my scripts' performance by having such trivial tasks
being done in one step.

Reproduce code:
array( 'id' => 1, 'foo' => 'bar' ),
array( 'id' => 2, 'foo' => 'bar' ),
array( 'id' => 3, 'foo' => 'bar' ),
array( 'id' => 4, 'foo' => 'bar' ),
array( 'id' => 5, 'foo' => 'bar' )

$out = array_***xx( $in, 'id' );

array( 1, 2, 3, 4, 5 );
