PHP 2 dim Array to 1 dim array -

is there built in function following?

$a[] = $b[0]['foo']; $a[] = $b[1]['foo']; $a[] = $b[2]['foo']; etc..

i realize can following:

foreach($b $c) {     $a[] = $c['foo']; }

but curious if there built in array function this. thanks.

in short: no.

in long: maybe ;) because not "directly built-in"

with php5.3

$a = array_map (function ($entry) {   return $entry['foo']; }, $b);

or before

$a = array_map (create_function ('$entry', 'return $entry[\'foo\'];'), $b);

at least second solution prefer foreach-loop ;)
