Value of a string making the name of another string

thenetbrainbox

I have a selection of 10 strings:

$post0[0]
$post1[0]
$post2[0]
$post3[0]
$post4[0]
$post5[0]

ect

$loopnum = 0 and has 1 added to it each time it goes round the loop.

In the loop I need to specify the string name $post*[0] replacing the star with the value of $loopnum.

$post$loopnum[0] does not work becasue it thinks I meen part 0 of $loopnum rather than $post.

Hopefully that makes sence. How would I do this?

You may look at the eval() funciton. You probaby could do something like

eval("$post" . $loopnum . "[0]");

Not sure if this is what you are looking for...

Just thought of something else.. and suprised no one else has mentioned it...

Why not use a 2 Diminsional array....

$post[x][y]

thus you dont need all the different variables.. can just do $post[$loopnum][0]
