something wrong with number being cut off to 1 digit

ok, I wrote a little php script that seems to be working, but somehow, 1 of the var keeps getting cut off. it is a script to process info from a form.

here is a part of the php code:

$episode[0] = $_POST['episode'];
$pDay[0] = $_POST['day'];
echo $episode[0]."<br>".$pDay[0];

PHP:

this is the form code:

<input type="text" name="episode" size="3" maxlength="3">
<input type="text" name="day" size="3" maxlength="2">

HTML:

when I input 120 for 'episode' and 22 for 'day', the output should be:
120
22

instead, I got this:
1
22

what happens is that the 120 is being cut to the first number "1", with "20" omitted. I have no idea why this is happening. if there is an error, why is it that $pDay is working fine? pls help. I am out of ideas.

 

Strange nothing looks wrong in the code...

do 1 thing try it without the arrays and see if it works properly or no and post it here

 

it works if I am using $episode instead of array. any ideas? I need arrays because I am using a for loop with $episode[$n] and $n as a counter. it cant be the for loop fault because I used an echo before the for loop, right at the start of the script.

 

yes it would be better if u post the full code

 

<form action="process.php" method="post">
<h3>Number of Episodes:</h3>
<select name="epcount">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
</select>
<br /><br />
<h3>First Episode:</h3>
<input type="text" name="episode" size="3" maxlength="3">
<br /><br />
<h3>Month:</h3>
<select name="month">
<option value="1">January</option>
<option value="2">February</option>
<option value="3">March</option>
<option value="4">April</option>

<option value="9">September</option>
<option value="10">October</option>

<br /><br />
<h3>Day:</h3>
<input type="text" name="day" size="3" maxlength="2">
<br /><br />
<input type="submit" name="submit" value="Preview">
<br /><br />
</form>

HTML:

<?php
$textMonth = array( "", "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", 

"November", "December");

$pDay[0] = $_POST['day'];				//set the first day
$episode[0] = $_POST['episode'];			//set the first episode
$pMonth[0] = $_POST['month'];				//set the first month
$count = $_POST['epcount'] - 1;

for ($n=0; $n<=$count; $n++) {
if ($n!=0) {						//calculate the next episode values
	$i = $n-1;					//i is the previous episode
	$episode[$n] = $episode[$i]+1;
	$pDay[$n] = $pDay[$i]+7;
	if ($pDay[$n]>$dayLimit) {			//check if it exceeds to the next month
		$pDay[$n] = $pDay[$n]-$dayLimit;
		$pMonth[$n] = $pMonth[$i]+1;		//change to the next month
	}
	else $pMonth[$n] = $pMonth[$i];
}

							//find the last day of the month
if (($pMonth[$n]==1)||($pMonth[$n]==5)||($pMonth[$n]==7)||($pMonth[$n]==10)||($pMonth[$n]==12))
	$dayLimit = 31;

else if (($pMonth[$n]==2)||($pMonth[$n]==3)||($pMonth[$n]==11))
	$dayLimit = 29;

else
	$dayLimit = 30;
}
?>

PHP:

there it is. I removed the echo commands from the php though.

 

ok, I have fixed the problem. I still do not know why array doesn't work. I removed array $episode[$n] and replaced it with $_POST['episode'] instead, with the command $_POST['episode']++ placed in the if statement. much cleaner coding I think.
