Question

I want to sort values of an array in alphabetical order in PHP. If all values started with same character then they should be sorted using second character and so on. Ignore case sensitive.

For Example:

before:
values[0] = "programming";
values[1] = "Stackoverflow";
values[2] = "question";
values[3] = "answers";
values[4] = "AA Systems";

after:
values[0] = "AA Systems";
values[1] = "answers";
values[2] = "programming";
values[3] = "question";
values[4] = "Stackoverflow";

I have found some algorithms but I want a way that is fast and with small number of statements. Ignoring case sensitive is special for me. Thanks.

See

• natcasesort: http://www.php.net/manual/en/function.natcasesort.php
• usort: http://www.php.net/manual/en/function.usort.php with a comparator function that compares strtolower(a) and strtolower(b).
