array_splice($a, 1, 1);

This will remove the second element, and reset the keys.

array

Hi,

Let's say I have the following array:

$myArray = array(array('1','2','3'), array('4','5','6'), array('7','8','9'),

array('10','11','12'));

How do I remove say the second element?

I have tried: $myArray = array_splice($myArray, 1, 1);

But this seems to remove the second element as well as all the following 
elements and I am left with:

$myArray = array(array('1','2','3'));

when I really want:

$myArray = array(array('1','2','3'), array('7','8','9'), 
array('10','11','12'));


Thanks,
Don

 elements and I am left with:

Yep. He had been using the return value of array_splice(), which is just
the spliced elements--not the resulting array post-splice.

Not on the specific sub element. I.e unset($array[2][0])

Yup, thanks.

Also execute:
   $array = array_values(array)
in order to fix the indexes
