array_sort problems

[Anon]

Hi everyone, I'm having some trouble with the array_sort function - one value always gets returns false, when it shouldn't. At least I think thats the problem - I must admit, I'm getting more than a little confused here.

My array is something like this:

$mntharr[0] = 12
$mntharr[1] = 11
$mntharr[2] = 10
$mntharr[3] = 9
$mntharr[4] = 8

and my code is this:

			for ($i=1; $i < 13; ++$i) {
				if((array_search($i, $mntharr)) != false) {
					echo("<td><a href=\"showtour.php?y=".($y)."&m=".$i."\">".date("F",mktime(0,0,0,$i,1,2000))."</a></td>");
				} else {
					echo("<td>".date("F",mktime(0,0,0,$i,1,2000))."</td>");
				}
			}

Initially, I thought this was working fine - but then I realised that the first value in the array ($mntharr[0]) never returns true in the array_sort function. In this case, 12 - so the hyperlink doesnt get output.

What am I doing wrong here?

1. Why do you complain about array_sort when you don't use it in the code?

2. Element number zero doesn't show up bevause your loop starts a $i=1.

Sorry, I meant array_search, not array_sort.

And, I could be wrong, but doesnt the loop starting at $i=1 not make a difference - array_search searches the array for a given value - $i isn't used as an index for the array.

Not sure, but try replacing the conditions in for to

$i=1;&i<13,$i++

I could be wrong, but you are preincrementing $i before you begin the for statement, thus $i starts at 2 (am I right or wrong on this, anyone?). Of course, thats just me.

This could be the problem in that for every loop the intenger is preincremented. Its worth a shot.

HTH, let me know if it works.

HMm.. indeed the $i=0 doesn't make a difference.

What does mak a difference is that array_search() returns the key of the value that was found, or FALSE if it was not found.
Problem: FALSE == 0
So you can't tell wether array_search() returned a FALSE, or a value of zero.
So indeed if the value is found at position zero, then array_search() will return the same value as when the value is not found.
Try in_array() instead.
