[Editor's Note: that change is listed in the "Changed functions" section.] The substr function has also been changed in a backward incompatible way. <?php substr("test",4); # false in PHP 5, "" in PHP 7 ?> In fact, this is the only thing we had to change in a number of places for our code base to run on PHP 7. It's definitely an improvement though, as the old behavior tended to cause bugs in border cases. --was-- The substr function has also been changed in a backward incompatible way. <?php substr("test",4); # false in PHP 5, "" in PHP 7 ?> In fact, this is the only thing we had to change in a number of places for our code base to run on PHP 7.
