How to convert a string with numbers to an array with integer elements?

Question

I have a string like this: '3,6,43,8'.

I can convert it to an array easily:

$newArray = explode( ',', $string );

but as I need integer elements in the array, I should convert every array element to an integer:

foreach( $newArray as $key => $sNumber ) {
    $newArray[ $key ] = intval( $sNumber );
}

Is there a way to directly convert the array elements to integers, instead of strings?

np buddy! just make sure, you scout SO and google properly :D — Manish Mishra, Dec 30 '13 at 11:45

You can use $inty = array_map('intval', explode(',', $string));

try this

$val = '3,6,43,8';
$integerIDs = array_map('intval', explode(',', $val));
var_dump($integerIDs);

with var_dump you can check it type.
