Getting Array length

[sanjdhiman]

Hi thereone more quick one

I need to try and get the length of an array i.e. number of elements in it so that i can run a for loop and limit the number of loops by the number of elements in the array

any ideas

thanks in advance

Sanj,

Use the foreach() statement. It terminated with the last element in the array. No counting necessary.

if you'd like to count though, just use

count($array);

the foreach statement is great though...

thanks guys for the advice well test them out

ok i tried the count method.. but that gives me some really dodgy answers

basically if a check box is set i.e. has a value in it (when it is check) it will add that check box item to the array.

no for example i clicked on one check box u would think that if i pass count($region)

it would just have one element but it gives me 6

and if i choose 2 items it gives me 5
and after that i stopped trying

but u know wat that can be?

not a clue without seeing alot more code...

but here's something you can do in your script to help you figure it out.

echo &quot;<pre>&quot;;
print_r($_POST);

or if you're using GET as your form method
print_r($_GET);

Then you can see all sorts of nice information.
