php - return monodimensional-array from multidimensional -

i have multidimensional array:

$array=array( 0=>array('text'=>'text1','desc'=>'blablabla'),               1=>array('text'=>'text2','desc'=>'blablabla'),               2=>array('text'=>'blablabla','desc'=>'blablabla')); 

is there function return monodimensional array based on $text values?

example:

monoarray($array); //returns: array(0=>'text1',1=>'text2',2=>'blablabla'); 

maybe built-in function?

this return array first values in inner arrays:

$ar = array_map('array_shift', $array); 

for last values do:

$ar = array_map('array_pop', $array); 

if want take element inner array's, must wrote own function (php 5.3 attitude):

$ar = array_map(function($a) {     return $a[(key want return)]; }, $array);
