Mulitpul variables into one

[almightyegg]

I have this script:

if($crops[start2] > $gap5start){
$select2 = "$crops[start2]";
echo "<br><br><br>$select 2<br><br><br>";
}
if($crops[start3] > $gap5start){
$select3 = "$crops[start3]";
echo "<br><br><br>$select 3<br><br><br>";
}
if($crops[start5] > $gap5start){
$select5 = "$crops[start5]";
}

 

Then I want to put the $selectX variables into a min() function.

As you probably know you need a comma and a space between eache vairable in the min() func.

 

So I was wondering if there was a function that I could use to stitch these together into one variable:

min($variable);

The problem is that the values aren't always set, and if they aren't set then you don't need a comma space

 

Hope that made sense

min($array) will return the lowest number in the array

Didn't work..

$select = array($select1, $select2, $select3, $select5);
$gap5fin = min($select);

 

$gap5fin is blank...

 

Unless it's counting the unset variables as 0s? Which would be lower

I managed to sort that but I have a similar issue elsewhere:

$gaps = array($gap1start, $gap2start, $gap3start, $gap4start, $gap5start, $gap6start);

$count = count($gaps);

echo "$count";

 

I was hoping that would count  the variables that are set.

In my case for testing $gap1start, $gap2start, $gap4start and $gap4start are all empty, so I want it to count 2 (as only 2 of the array actually have any value)

 

Is there another way?

What happens if you go

 

foreach ($gaps as $arrvalues) {
if (isset($arrvalues)) {
echo "$count";
}

}

 

Does that work for you?

You could go through the array and remove empty values, but it seems there would be a better way using an array from the beginning. So, store everything in $gaps from the start, but if you don't use #2, just don't set the value for #2. So you're array would end up looking like:

array(
  1 => 'value 1',
  3 => 'value 3',
  4 => 'value 4',
)
