note 120197 added to language.operators.comparison

I think PHP compare arrays with <=> operator like the following: echo [12, 11, 100] <=> [12, 20, 3]; it initiate a counter for this comparison and then compare each entry like following: counter for this comparison will initiated with zero: counter = 0 after that it compare like following: a == b this mean the count operation will be counter = counter + 0 a > b this mean the count will be counter = counter + 1 a < b this mean the count will be counter = counter - 1 12 == 12 -----> counter = counter + 0 11 < 20 -------> counter = counter - 1 100 > 3 -------> counter = counter + 1 and if the counter remain zero after these comparisons, it will try to find the first different value and produce it as a final result, SO because the first element is 12 in both arrays the second one will be tested and because it is different the final result will depend on it and 'echo' will produce -1 because 11 is less than 20. test the following to be sure: echo ([12, 100, 11] <=> [12, 3 ,20]).PHP_EOL; echo ([12, 11, 100] <=> [12, 20 ,3]).PHP_EOL; echo ([11, 12, 100] <=> [20 ,12 ,3]).PHP_EOL; it just an idea I don't test it carefully BUT to help in some way thanks!! ---- Server IP: 72.52.91.14 Probable Submitter: 37.236.112.15 ---- Manual Page -- http://php.net/manual/en/language.operators.comparison.php Edit -- https://master.php.net/note/edit/120197 Del: integrated -- https://master.php.net/note/delete/120197/integrated Del: useless -- https://master.php.net/note/delete/120197/useless Del: bad code -- https://master.php.net/note/delete/120197/bad+code Del: spam -- https://master.php.net/note/delete/120197/spam Del: non-english -- https://master.php.net/note/delete/120197/non-english Del: in docs -- https://master.php.net/note/delete/120197/in+docs Del: other reasons-- https://master.php.net/note/delete/120197 Reject -- https://master.php.net/note/reject/120197 Search -- https://master.php.net/manage/user-notes.php
