Problem:
$data = array(“A”,”M”,”X”,”b”,”d”,”E”,”l”);
I need to sort the data base on value. When I use asort($data), got the following:
[0] => A
[5] => E
[1] => M
[2] => X
[3] => b
[4] => d
[6] => l
In the above example, “b”,”d” and “l” starts with a lower case but ends after “X” which has an upper case.
How can we sorts it where it ignores whether the words start with upper case or lower case?
I was expecting this
[0] => A
[3] => b
[4] => d
[5] => E
[6] => l
[1] => M
[2] => X
Solution:
Use natcasesort($data); and you will get the exact same result.
Notes:
We can use this function to sort our arrays using a case insensitive “natural array” algorithm. natcasesort() is a case insensitive version of the natsort().
Syntax:
bool natcasesort ( array &$array );
Returns
Returns true in case of success and false for failure.
