PHP Going through array?

Question

I have a $search_array like this

Array
(
    [1] => Array
        (
            [type] => book
            [search] => steve
        )

    [2] => Array
        (
            [type] => book
            [search] => john
        )


foreach ($search_array as $s) {

    $arrayid = //???????
    $searchtype = $s['type'];
    $search = urlencode($s['search']);

getResult($arrayid);

}

I'm trying to figure out how to get the array number. So for the first result i need $arrayid to be 1. How do I reference that in the foreach loop?

Thanks

Use a foreach with "$key => $value"

Array
(
    [1] => Array
        (
            [type] => book
            [search] => steve
        )

    [2] => Array
        (
            [type] => book
            [search] => john
        )

foreach ($search_array as $key => $s) {

    $arrayid = $key
    $searchtype = $s['type'];
    $search = urlencode($s['search']);

getResult($arrayid);

}

Adding $arrayid => in your foreach loop declaration will auto-assign $arrayid with the current array index.

foreach ($search_array as $arrayid => $s) {
  // ...
  getResult($arrayid);
}

See foreach on PHP Manual.

foreach ($search_array as $arrayid => $s) {

Please read PHP documentation before asking such basic questions

@vpets a very simple search would have helped a lot.

This is a way you could retrieve data from a Php array. It will retrieve all entries from array $value and their key $key.

foreach ($array as $key => $value) {
  // $key is the array index
}
