Php array sorting sort problem.

has the following array: $arr = ["abc"," ABC", 0.23, "Begin"," oh", 11,456, "sort"," EMAIL"] ;

Why is it sorted using sort ($arr), sort ($arr, SORT_STRING), sort ($arr, SORT_NUMERIC) respectively?

["ABC","Begin","EMAIL","abc","oh","sort",0.23,11,456]

["abc","ABC","Begin","oh","sort","EMAIL",0.23,11,456]

[0.23,11,456,"ABC","Begin","EMAIL","abc","oh","sort"]

PHP documents are really the best written and easiest to read in all languages. Take a look at them. There is no such treatment for learning other languages. sort
