Searching an ARRAY

[dcjones]

Hi all,

I am trying to find out if an array contains a string of numbers.

If I use the following statement I get this result:

print_r ($data);

Array ( [i_agree] => 1 [status] => Array ( [3] => 1 [19] => 1 [87] => 1 [89] => 0 [99] => 0 [104] => 1 [107] => 1 ) [is_active] => 1 [signup_email_sent] => 1 [is_locked] => [aff_paypal_email] => [selected_lang] => en )

The code I am using is:

$result = 	$row_members['data'];
$data = unserialize($result); 
if(in_array("107", $data)) {
echo  "107 is in the Array";
} else {
echo "107 is NOT in Array";
}	

The result of runniung the code is always "107 is not in Array".

I know I'm doing something wrong but what?

Can anyone help or advise please.

It looks like you are trying to determine if 107 is a key in this array, so you should use [man]array_key_exists/man instead of in_array().

Hi LaserLight,

Many thanks for a fast reply.

I am now working with:

$result = $row_members['data'];
			$data = unserialize($result); 
			$search_array = array($data);
			if (array_key_exists('107', $search_array)) {
   				 echo "The '107' element is in the array";
			}

When I run the code there is nothing displayed.

array_key_exists is new to me. Any ideas.

Oh, that's because your array has an element that is an array. Do you know what is the structure of your array? If not, then apply this recursively.

For example, in what you posted "107" isn't a key of the $data array, it's a key of the $data['status'] array.
