Another question that has probably been asked a 1000 times

Using the following example:

$myFile = "optionList.txt"; 
$myOptions = fopen($myFile, "r"); 
$lock = flock($myOptions, LOCK_SH);
if ($lock) { 
 $options_read = fread($myOptions, filesize($myFile));
 $lock = flock($myOptions, LOCK_UN); } 
fclose($myOptions); 
$exp_Options = explode(",", $options_read);
$number = 20;
$x = 0;
while ($x < $number) {
$namenumber = $x + 1;
echo "<option value = '$exp_Options[$x]'>$exp_Options[$x]</option>";
++$x;
}

Is it possible to rewrite this so that $number will equal the correct number of entries that were exploded, regardless of how many there are at the time?

I am trying to work this so that I do not need to go in and edit the variable $number everytime the text file changes.

This snippet is part of a code for filling in an option list (dropdown) and may contain, on any given day, from 1 to 20 entries. Leaving $number equaling 20 outputs a dropdown with (at times) 3 actual entries and 17 blank ones. Which just looks really tacky in my opinion.

Thanks in advance!

Try:

$number = count($exp_Options);

I would iterate the array with foreach:

foreach($exp_Options as $key => $value){
   echo "<option value = '$value'>$value</option>";
}

No counting necessary.

For crying out loud! Why didnt it occur to me to use a foreach statement? After all, I just got through coding another part of my script using it. LOL

Thanks DRJ478 for hooking the truck up and pulling my head out.
