Question

I have a multidimensional array:

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

Is there a function to return a monodimensional array based on the $text values?

Example:

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

Maybe a built-in function?

Answer 1

This will return array with first values in inner arrays:

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

For last values this will do:

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

If you want to take another element from inner array’s, you must wrote your own function (PHP 5.3 attitude):

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