i keep getting this error
Warning: Invalid argument supplied for foreach() in ...\functions.php on line 448
this is the code
foreach($holidays as $key => $value)
Are you sure $holidays is an array and holds some values?
Yes, I am sure $holidays is an array. Could it be the fact that i never actually declared it as an array? I merely did like $holidays[] = bla bla somewhere along the line and it became an array. How do I declare an array tho? just like array $holidays like that?
$holidays = array();
That will setup $holidays as an array...
thx! ill see if that fixes the problem
If you just wanna check to see if something is an array, use is_array($var)
o yea thats rite... :o
Other fun array tricks:
print implode("::",array_keys($array)); print implode("::",array_values($array));
So before using foreach (especially on variables that may or may not be arrays, or may or may not hold values), you should check both is_array() and count() as if no values exist you should do something else (like yell at the user!).
