[RESOLVED] Problem with sort()

[mparab]

Hi,

I problem with my sort() function. I have created a page that will display a list of open forms that are available to be edited or closed. The page gets this list from an array that is populated from a database. Problem is there are no records in the database, hence nothing in the array, and now i get a sort() error:

Warning: sort() expects parameter 1 to be array, null given in /home/www/intranet/NonCon/close.php on line 50

I believe it's because the array is empty, but if anyone has any ideas i would be very grateful.

Why not check if its an array before calling sort() or get the sort() function to check if its an array before executing?

How would i do that? Sorry i'm a newb.

[thorpe]

if (is_array($arr)) {
  // do sort
}

Something like

if (is_array($my_arrray)){
  	//do something if it is an array
  } else {  	
 //do something else if it is NOT an array
  }
