Previous Comments: ------------------------------------------------------------------------ [2005-09-16 14:01:14] soletan at toxa dot de Description: ------------ Is it possible to have an array_xxxx-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: --------------- before: array( 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' ) ); action: $out = array_xxxxx( $in, 'id' ); result: array( 1, 2, 3, 4, 5 ); ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=34526&edit=1
