#21728 [NEW]: Additional (kindly weird example) for sort()

From: andrey@php.net Operating system: All PHP version: 4.3.0 PHP Bug Type: Documentation problem Bug description: Additional (kindly weird example) for sort() Today I closed bug #21444. The user has to master the type juggling to know the expected output. I think that it is good idea to add it's example as comprehensive one. The script goes here (the explanation is after it) : <?php $arr1 = array("a","b","c","d","4",5,4,"true","TRUE",true); sort($arr1); var_dump($arr1); ?> The output is : array(10) { [0]=> bool(true) [1]=> int(4) [2]=> string(1) "4" [3]=> string(4) "TRUE" [4]=> string(1) "a" [5]=> string(1) "b" [6]=> string(1) "c" [7]=> string(1) "d" [8]=> string(4) "true" [9]=> int(5) } It may look strange - why (int)5 is after all the strings. This is because "4" is lower than (int) 5, "4" is before "true" and "true" is before 5. The first 2 are obvious, the third one is not. But it is ok. It's better not to mix types in the array. If 5 is changed to "5" then "5" goes right after "4".
