Update value in inner array

This may be very simple question, sorry about my lack of knwoledge, and my stupidity...

After adding Items to array,

$List[1] = array(
    'Id' => 1,
    'Text'=> 'First Value'
);

I need to change the value of an item in inner array,

foreach ($List as $item)
{
    $item['Text'] = 'Second Value';
}

But when i check Value remains same

foreach ($List as $item)
{
    echo $item['Text']; //prints 'First Value'
}

How to update the value to 'Second Value'?

    $item['Text'] = 'Second Value';

You can either set it directly:

foreach ($List as $key => $item)
{
    $List[$key]['Text'] = 'Second Value';
}

Or set it by reference:

foreach ($List as &$item)
{
    $item['Text'] = 'Second Value';
}

There may be a PHP-ish mystical Perl way to access the value, but I find it simpler to loop through the array and set the value directly.

for($i = 0; $i < count($List); $i++)
{
    $List[$i] = 'Second Value';
}

Edit: Curiosity got the better of me. http://www.php.net/manual/en/control-structures.foreach.php

foreach($List as &$item)
{
    $item = 'Second Value';
}

Notice the & which causes $item to be used by reference instead of by value.
