Compare Items in an array...

[Syto]

Hi all! Very new to php (current running php 4.4) and I am really getting into it!

 

I have been getting on fine with basic coding until I stumbled accross a problem. I cant seem to figure out how to check to see if a value in one array is in another array - and if so just simple report back "true" or "false".

 

Lets call the two arrays LOCKS and KEYS.

 

Doing a print_r($locks) would give:

 

Array ( [0] => 9 [1] => 17 [2] => 26 [3] => 27 [4] => 28 [5] => 31 [6] => 34 [7] => 38 [8] => 40 [9] => 41 [10] => 46 [11] => 49 [12] => 53 [13] => 54 [14] => 56 [15] => 60 [16] => 10 [17] => 11 [18] => 14 [19] => 19 [20] => 20 [21] => 22 [22] => 21 [23] => 23 [24] => 24 [25] => 25 [26] => 29 [27] => 30 [28] => 32 [29] => 33 [30] => 36 [31] => 37 [32] => 39 [33] => 42 [34] => 43 [35] => 44 [36] => 45 [37] => 47 [38] => 48 [39] => 50 [40] => 51 [41] => 52 [42] => 55 [43] => 58 [44] => 8 [45] => 12 [46] => 16 [47] => 18 [48] => 35 [49] => 59 [50] => 57 [51] => 13 [52] => 65 )

 

and doing a print_r($keys) would give:

 

Array ( [0] => 1 [1] => 2 [2] => 4 [3] => 20 [4] => 65 )

 

What I want to do is jsut test to see if any value from the $key array is in the $lock array.

 

There maybe be more than one available but I just want it to report back a true or false value...

 

Any help would really be appreciated!

 

thanks!

Try:

<?php
if (in_array(array_values($keys), $locks))
{
    //true
}
else
{
    /false
}
?>

 

Edit: hmm don't think this will work. I will try to work up something else, in the meantime someone else might have a solution...

Thanks but that didnt appear to work.

 

I'm pretty stumped on how to get this working  :-\

[Syto]

Ok I seem to have found a solution but it seems to be very "dirty".

 

What do you think to this:

 

<?php
foreach($locks as $needle){

		if (in_array($needle, $keys)) {

			$valid = true;

		} 

	}

if ($valid != true) {

	echo "denied";
	exit();

}
?>

I've just found out how to do and I have been doing it alot

 

the way I do it:

 

function main_nav()
{
$main_nav = array(
	"names" => array("Home", "Pictures", "Templates", "Website Coding", "Search"),
	"pages" => array("index.php", "pictures.php", "templates.php", "website_coding.php", "search.php"),
);


$count_main = count($main_nav['names']);
$i_main = 0;	

while($i_main < $count_main)
{
	$links_main .= " <a href=\"".$main_nav['pages'][$i_main]."\">".$main_nav['names'][$i_main]."</a> ";
	$i_main++;
}
echo $links_main;
}

 

That is an exaple of one of mine it might help....
