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".
Thanks
