in_array not working

I have the following result in an array:

Array ( [0] => Array ( [x_list_id] => 14 [client_id] => 6 [list_id] => 36 [x_list_name] => Chocolate [x_list_option] => choice [x_list_price] => 0 [x_list_status] => active [x_list_added] => 2007-10-09 17:20:35 ) [1] => Array ( [x_list_id] => 17 [client_id] => 6 [list_id] => 36 [x_list_name] => Cookies and Cream [x_list_option] => choice [x_list_price] => 0 [x_list_status] => active [x_list_added] => 2007-10-09 17:21:17 ) [2] => Array ( [x_list_id] => 13 [client_id] => 6 [list_id] => 36 [x_list_name] => Haagen-Dazs [x_list_option] => choice [x_list_price] => 0 [x_list_status] => active [x_list_added] => 2007-10-09 17:20:22 ) [3] => Array ( [x_list_id] => 16 [client_id] => 6 [list_id] => 36 [x_list_name] => Strawberry [x_list_option] => choice [x_list_price] => 0 [x_list_status] => active [x_list_added] => 2007-10-09 17:21:03 ) [4] => Array ( [x_list_id] => 15 [client_id] => 6 [list_id] => 36 [x_list_name] => Vanilla [x_list_option] => choice [x_list_price] => 0 [x_list_status] => active [x_list_added] => 2007-10-09 00:00:00 ) ) 

PHP:

</DIV>
and i am trying to find if some value exits using the in_array function but can get it to run properly:

if(in_array("choice",$rows)){ $choice = "true";}if(in_array("standard",$rows)){ $standard = "true";}
if(in_array("extra",$rows)){ $extra = "true";}

PHP:

what am I doing wrong here?

 

Are you sure you're building your array correctly? If what you put there is the code you are using, then the variable "$rows" doesn't actually exist. As far as I can tell your in_array code looks alright. That means the error is probably in how the array is being built.

 

this is how I bulid the array

if ($nTotalRecsListX > 0) {
		$rows = array();
		while($rowListX = phpmkr_fetch_assoc($rslistX)){
			$rows[] = $rowListX;//build array list
		}
		//print_r($rows);
	}

PHP:

 

And you've echoed the array to make sure that those values definitely are in the array, right?

 

That's where the first code posted above is coming from (print_r($rows)

 

Hmm... is the $row array being populated within a function? Or is it on the same level as the other code?

 

in_array() does not work recursively. Use this function instead.

function in_array_recursive($needle, $haystack, $strict = false)
{
	foreach ($haystack AS $hay)
	{
		if (is_array($hay))
		{
			return in_array_recursive($needle, $hay, $strict);
		}
		else if ((!$strict AND $hay == $needle) OR ($strict AND $hay === $needle))
		{
			return true;
		}
	}
	
	return false;
}

Aha! I was scratching my head at that one. Good job, nico_swd! Rep for you!

 

this is what I did and it works fine.

I was already looping through the arrays to write certain values but never came to me that i should do another loop to see if in_array.

anyhow this is what i sis and it works:

foreach($rows as $row){ 
                                if(in_array("choice",$row)){ $choice = "true";} 
                                if(in_array("standard",$row)){ $standard = "true";} 
                                if(in_array("extra",$row)){ $extra = "true";} 
                        }

Thanks for help.
