Howto delete an element in 2D/3D array?

[spstieng]

It easy to delete an 1D array element by using UNSET.

I think this leaves an empty space? The empty space needs to go too. I need to use it in an 2D and 3D array.

This here doesn't work 🙁

$ar =array (
			array('a','b','c',),
			array('d','e','f',)
		);

foreach ($ar as $t)
  foreach ($t as $m)
    echo $m.'<br>';

unset($ar[0][1]);     <------ trying to remove

foreach ($arrTest as $t)
  foreach ($t as $m)
    echo $m.'<br>';

Is there an algorythm for this kind of deletion?

Any help apprechiated.

$ar =array (
			array('a','b','c',),
			array('d','e','f',)
		);

foreach ($ar as $t)
  foreach ($t as $m)
    echo $m.'<br>';

$l_ar = $ar[0]
unset($l_ar[1]);

foreach ($arrTest as $t)
  foreach ($t as $m)
    echo $m.'<br>';

[spstieng]

$l_ar = $ar[0];
unset($l_ar[1]);

Sorry, didn't work. The output I get is:

first
a
b
c
d
e
f
second

ooppss

$ar =array (
			array('a','b','c',),
			array('d','e','f',)
		);

foreach ($ar as $t)
  foreach ($t as $m)
    echo $m.'<br>';

$i=0;
$l_ar = $ar[$i]
unset($l_ar[1]);
//add these two lines.
unset($ar[$I]);
$ar[$i] = $l_ar;


foreach ($arrTest as $t)
  foreach ($t as $m)
    echo $m.'<br>';
