I'm not sure how much clearer that can be.

And substr sometimes returns string, sometimes boolean (see #52628). So developers are forced to use (string) substr($s, 0, ...) everywhere. It should be emphatically stated in the documentation. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52631&edit=1
