pulling values out of arrays and into strings

I have an array like this:

print_r($GA); //provides these results

Array (
 [0] => Array ( [LABEL] => GAD ID [TYPE] => text [NAME] => GA_ID [VALUE] => 1707444616535 )
 [1] => Array ( [LABEL] => GAd 1 [TYPE] => text [NAME] => GA_1 [VALUE] => 6780673118 )
 [2] => Array ( [LABEL] => GAd 2 [TYPE] => text [NAME] => GA_2 [VALUE] => 3745034999 )
 )

I need to pull those VALUEs out as strings and have this :

$GA_ID = // the value of GA_ID
$GA_1 = // the value of GA_1
$GA_2 = // the value of GA_2

I'm not array-smart.  How is this done?

Thank you,                Chris

You would need to separate name, value pairs from the array first, then use extract:

foreach($GA as $array) {
     $newArray[$array['NAME']] = $array['VALUE'];
}
extract($newArray, EXTR_SKIP);

ah, ok, then I proceed like this?

echo $newArray['GA_ID'];

that's what seems to work from some quick experimenting

No.  You asked to have variables like this:

$GA_ID = // the value of GA_ID
$GA_1 = // the value of GA_1
$GA_2 = // the value of GA_2

and that's what I gave you.  If you echo the values you will get the following:

echo $GA_ID; // displays 1707444616535
echo $GA_1; // displays 6780673118
echo $GA_2; // displays 3745034999

Isn't this what you asked for?

If you actually wanted it to be in the $newArray['GA_ID'] format, simply get rid of the extract statement.
