prob with array

[Anon]

hi,

i got the following arrays:

$ar = array(1,2,3,4,5);
$ar2 = array(1,4,5);
etc.

now i got a variable submitted via a form, $var, which's content is the name of one of the above arrays, e.g. "ar2".

and now i want to do: echo $var[1], e.g.
i don't get the desired "4", but "r". so i get the second element of the array's name, not of its content...

any hints? tia!

You'll have to post the real code. I suspect the "r" is from the word "array", not the variable name. You don't have what you think in $ar2.

the html must be like:
<form mehtod="post">
<input type="text" name="var[]" value="1">
<input type="text" name="var[]" value="2">
<input type="text" name="var[]" value="3">
<input type="text" name="var[]" value="4">
</form>
and now when u got the var in php u must write:

$ar=$HTTP_POST_VARS["var"];

now the $ar[0]=1; ... $ar[3]="4"

Did you try to input stuff directly on it?

$ar[0] = 1;
$ar[1] = 2;
$ar[2] = 3;
$ar[3] = 4;
$ar[4] = 5;

$ar2[0] = 1;
$ar2[1] = 4;
$ar2[2] = 5;

I don't know if it's the best way but it's working like this...
