Unset in Multidementional Array

[hmvrulz]

i have an array $this-data['Phone'] ( am using cakephp framework)

output of this give this.

Array
(
    [0] => Array
        (
            [number] => 23467887
        )

[1] => Array
    (
        [number] => 
    )

[2] => Array
    (
        [number] => 23563866
    )

[3] => Array
    (
        [number] => 
    )

[4] => Array
    (
        [number] => 11222
    )

)

i wanna unset the [1] and [3] because it doesnt have any values for the number.

i want a an array returned like this

Array
(
    [0] => Array
        (
            [number] => 23467887
        )


[1] => Array
    (
        [number] => 23563866
    )


[2] => Array
    (
        [number] => 11222
    )

)

Note: the key values have changed

After the all the manipulation all this should be stored in $this->data['Phone']

a foreach() loop is the first thing that comes to mind, but there are other ways

[hmvrulz]

i ahve done this. but since i wanna convert this into a function i dont thing its the right way

 pr($this->data['Phone']);

    foreach ($this->data['Phone'] as $key => $var) {

        if (empty($var['number'])) {
            echo "encountered a null value";
            unset($var);
            unset($this->data['Phone'][$key]);
        } else {
            echo "number exists <br/>";
        }
    }
    sort($this->data['Phone']);
    pr($this->data['Phone']);  

since am using this unset($this->data['Phone'][$key]);

i have anything array $this->data['Cellphone']
so how can i convert this to a function

[dagon]

<?php

$foo=array(
array('number' =>'23467887' ),
array('number' =>'' ),
array('number' =>'23563866' ),
array('number' =>'' ),
array('number' =>'11222' )
);


function clean_array($clean_me){
	foreach($clean_me as $key=>$var){
		if( !empty($var['number'])){
		$out[]['number']= $var['number'];
		}
	}
	return $out;
}

$foo2= clean_array($foo);

print_r($foo2);


?>
