Problem:<\/h2>\n

$data = array(“A”,”M”,”X”,”b”,”d”,”E”,”l”);<\/p>\n

I need to sort the data base on value. When I use asort($data),<\/strong> got the following:<\/p>\n

[0] => A
\n[5] => E
\n[1] => M
\n[2] => X
\n[3] => b
\n[4] => d
\n[6] => l<\/p>\n

In the above example, “b”,”d” and “l” starts with a lower case but ends after “X” which has an upper case.<\/p>\n

How can we sorts it where it ignores whether the words start with upper case or lower case?<\/h2>\n

I was expecting this<\/p>\n

[0] => A
\n[3] => b
\n[4] => d
\n[5] => E
\n[6] => l
\n[1] => M
\n[2] => X<\/p>\n

Solution:<\/h2>\n

Use natcasesort($data);<\/strong> and you will get the exact same result.<\/p>\n

Notes:<\/h3>\n

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().<\/p>\n

Syntax:<\/h3>\n

bool<\/strong> natcasesort ( array<\/strong> &$array );<\/p>\n

Returns<\/h3>\n

Returns true in case of success and false for failure.<\/p>\n
