How to get array of strings from output php

Question

I do a print_r($my_var)

and get a result like:

Array ( [0] => Array ( [email] => [email protected] ) [1] => Array ( [email] => [email protected] ) )

How to get a new array like

$mails=    array( '[email protected]','[email protected]' );

I was trying foreach ($myvar->result() as $val) $to .= $val->email . ", "; but to get rid ot that last comma? — edgarmtze

$mails = array_map(function ($x){
    return $x['email'];
}, $my_var);

Update

Using a foreach loop instead of array_map:

$mails = array();
foreach($my_var as $emailArr){
    $mails[] = $emailArr['email'];
}

Is it other way withouth using a mapping function?

@JohnBallinger array_values($my_var[0]) just returns an array containing the first email address, not all of them.

array_values($myvar[0]);

// Will return the values inside you array ( I noticed your array was nested, so I did the values of he 0 element).

Highly recommend just having a little read of all the available array functions just quickly so you can see what is possible.
