Problems with displaying array information

[DannyM]

I've run into another rut. This code halfway works, for some reason, even if a value in the array reads Newline, it still displays Newline instead of skipping to the next value. I'm not exactly sure what to do to fix it, so any help would be appreciated.

 

//displaying a page
//FORWARD
if(isset($_POST["next"]))
{

if($testArray[$_SESSION['current']]!=="Newline")
{
echo $testArray[$_SESSION['current']];
$_SESSION['current']=$_SESSION['current']+1;

}
else
{
$_SESSION['current']=$_SESSION['current']+1;
}
}


echo '
<form action="data.php" method="POST">
<input type="submit" name="next" value="Next"/>
<input type="submit" name="back" value="Back"/>
</form>';

add a bit of debugging code

 

if($testArray[$_SESSION['current']]!=="Newline")
{
     var_dump($testArray[$_SESSION['current']]);              // see what's really in there
     echo $testArray[$_SESSION['current']];
     $_SESSION['current']=$_SESSION['current']+1;

}

so... does the string "Newline" always appear exactly as you have it in your if statement...

 

maybe you could remove one of the = signs.  !="Newline"  instead of !=="Newline"

 

not identical versus not equal.  Im really not sure what your going for though

I am horrible with strings though

Can you show more code..?

 

My guess right now is either that $_SESSION['current'] isn't set, or the array wasn't set..

 

I tested it using a specific array of array('Newline', 'other'); and $_SESSION['current'] set to '0', and it went to the else like it was supposed to.
