Is there a way to delete a dimension in a array (only if it's empty), it's pretty dificult to explain with words, so that's what i want to do :
I have an array that returns :
(
[region1] => Array
(
[] => Array
(
[0] => citie1
[1] => citie2
)
[region2] => Array
(
[] => Array
(
[0] => citie1
[1] => citie2
[2] => citie3
)
)
)
I want it to be :
(
[region1] => Array
(
[0] => citie1
[1] => citie2
)
[region2] => Array
(
[0] => citie1
[1] => citie2
[2] => citie3
)
)
foreach($array as $key => $value) {
$array[$key] = reset($value);
}
That will replace each value in the outer array with the first element of that value.
