How to transfer one array to another array in php

Question

I have a simple Two array

    $ages[] = array("Peter"=>22, "Clark"=>32, "John"=>28);

    $ages1[] = array("demo"=>22);

When I print this arrays it should be like following:

Array
(
    [0] => Array
        (
            [Peter] => 22
            [Clark] => 32
            [John] => 28
        )

)
Array
(
    [0] => Array
        (
            [demo] => 22
        )

)

But I want to create third array which will be show demo kye value into first array like following:

Array
(
    [0] => Array
        (
            [Peter] => 22
            [Clark] => 32
            [John] => 28
            [demo] => 22
        )

)

Not sure what are you trying to achieve here...little more context would be helpful. But this is how you can do this,

$ages[] = array("Peter"=>22, "Clark"=>32, "John"=>28);

$ages1[] = array("demo"=>22);

$result[] = array_merge($ages[0],$ages1[0]);

This would do the job.

<?php    
$ages[] = array("Peter"=>22, "Clark"=>32, "John"=>28);
$ages1[] = array("demo"=>22);
$output = prepend_array($ages,$ages1);
print_r($output);

// Function to prepend arrays
function prepend_array()
{
    $num_args = count(func_get_args());
    $new_array = array();
    foreach (func_get_args() as $params){
        foreach($params as $out_key => $param)
        {
            foreach($param as $key => $value)
            $new_array[$out_key][$key] = $value;
        }
    }

    return $new_array;

}
