Girish,
First of all, it should be $myArray[0], not $myArray['0']. It has a
numeric index. And the fact count($myArray) has the correct value
indicates the values are correct.
Also, the way you have it coded, if the 'second value' checkbox is not
checked, myValue[1] will not be set and you'll get a notice if you try
to use it. Unless you absolutely have to have the indexes like that, a
better way is to use:
<input name='inp[]' type='checkbox' value='first value'>
<input name='inp[]' type='checkbox' value='second value'>
<input name='inp[]' type='checkbox' value='third value'>
Now inp[0] will contain the value from the first checked box, imp[1]
will contain the value from the second checked box, etc.
Also, I agree with Anthony but for different reasons. I suggest you use
POST instead of GET. Not because of the array (it should work in
either), but because it can get to be quite a long URL if the user
checks several boxes.
