I have a string that I converted to a multi-dimensional array.
String: 13,4,3|65,1,1|27,3,2
I wanna be able to move 27,3,2 to index 1 for example, so it would become:
13,4,3|27,3,2|65,1,1
Or remove one of those sections.
I know I can unset(), but I'm not sure how to search for an index then move it or unset it.
You can try the below one for interchanging the position of last two elements
$array = [0 => array(13,4,3), 1=>array(65,1,1), 2 => array(27,3,2)];
foreach($array as $key => $value) {
if($key == count($array)-1) {
$array[$key] = $array[$key-1];
$array[$key-1] = $value;
}
}
This is for removing the second element.
$array = [0 => array(13,4,3), 1=>array(65,1,1), 2 => array(27,3,2)];
foreach($array as $key => $value) {
if($key == count($array)-1) {
$array[$key-1] = $value;
unset($array[$key]);
}
}
Loop through the array using foreach
foreach($array as $key => $value)
From key you can get the key and can do whatever you like.
Other wise, you can do this if you know the key
echo $array['pass_key_name_here'];
