Quick questions

So I have

$x = 2;

But I added $x-1; it wont subtract 1 from the variable. Can someone help me here. Am I doing this wrong?

 

If you're always looking to subtract just 1, you can use --.

$variable = 5;
$variable = $variable--; //Now 4
$variable = $variable - 1; //Also 4

 

For some strange reason I have $x=2 at the top and I put in a certain area: $x= $x-1; and it doesnt subtract 1

 

Then you have done something else wrong. Why not post all the code? Or, in the privacy of your own home, simply stick in a bunch of:

echo "<p>x is now {$x}</p>";

throughout the code and then watch the progress of $x to see where it diverges from your expectations.

 

at the top I have
<?
$x = 2;
INCLUDES....
?>
Then I have a function and in that function it will display text

$x = $x -1;
echo "fiefieh"

It shows fiefieh

at the footer I have
<?=$x?>
and it shows 2 whats wrong

 

Try $x= ($x-1);
echo $x;

And the result should be the assigned value of X minus 1.

 

nothing changed

 

echoing "fiefieh" is not interesting or useful. echo $x.
