how do i increment a variable?
Hello,
I want to make a loop to create a bunch of variables, like this
i=0;
while($i<5){
$myvar . $i= "something";
$i=$i+1;
}
and I want to get "$myvar1, $myvar2, $myvar3" and so on but it's not working
I tried a bunch of stuff but i dont know what i'm doing wrong

Re: how do i increment a variable?
You've got the .$i in the wrong place
change it to:
$myvar = $i . "something";

Re: how do i increment a variable?
Your best bet in this situation is to use an array, really.
while ( $i < 5 ) {
$myvar[] = "something;
}
This will give you $myvar[1], $myvar[2], and so on, with the convenience of storing all of the values in one variable name ($myvar).
If you need to have seperate variables, try this instead:
$( 'myvar' . $i ) = "something";
This will give you the intended '$myvar1, $myvar2' and so on.

Ok so i think i got the arrays thing, but im not getting all 5 variables, i just get $my_var[1], $my_var[2], $my_var[3] and $my_var[4], but $myvar[5] is blank!
what am i doing wrong?

Re: how do i increment a variable?
Sorry yendii, that was my bad for being unclear.
When you create an array with that while loop, the indicies ( the [x] part of $my_var[x] ) always start at ZERO and not at 1, so your values start at $my_var[0] and go to $my_var[4], for a total of 5 elements (variables in the array)
Hope that clears it up for you!
