Hi all, Need help in solving this task using PHP built in function : array_reverse() and without it. Appreciate it in explaining the code as I'm completely a newbie. function reverseArray($Arr) { } $fruits = ["Mango","Strawberry","Bananas","Pineapple"]; $result = reverseArray($fruits); Many thanks,

I'm having trouble comparing two arrays. Ive never worked with arrays like this till today so bare with me. Ill explain as best I can with my code. So I have one array Im pulling from the database. which I get as follows //now get all the tags mysql_select_db($db, $db); $getq = mysql_query("SELECT * FROM blogtags",$db); //create the tags array $arr1 = array(); do{ $arr1[] = $row['tagname']; }while($row = mysql_fetch_assoc($getq)); If I print the outcome of this $arr1 array(3) { [0]=> NULL [1]=> string(4) "cars" [2]=> string(4) "vans" } cars and vans are the only 2 entries in the database Next I have a form field called $_POST['hidden-tags']; which stores data as ....... tanks, bikes, trains here is the code I have to turn that into an array $arr2[] = explode(",",$_POST['hidden-tags']); if I echo that out I get array(1) { [0]=> array(4) { [0]=> string(4) "cars" [1]=> string(5) "bikes" [2]=> string(6) "trains" [3]=> string(5) "tanks" } } which are entries into the form (cars, bikes, trains, tanks) Now Im trying to only show items that are not in the first array with array_diff but for some reason it doesnt work correctly. First I can see in the second array does not look like the first and I dont understand why but im sure thats coursing problems!!!!! secondly If I run the code //show only items in the second array that are not in the first $tmp = array_diff($arr2, $arr1); var_dump($tmp); then this pops out array(1) { [0]=> array(4) { [0]=> string(4) "cars" [1]=> string(5) "bikes" [2]=> string(6) "trains" [3]=> string(5) "tanks" } } surely this should just show bikes, trains, tanks and not the cars as it appears in $arr1
