Edit report at https://bugs.php.net/bug.php?id=73613&edit=1 ID: 73613 Updated by: requinix@php.net Reported by: ua dot san dot alex at gmail dot com Summary: Not warning if length == 0 Status: Open -Type: Bug +Type: Documentation Problem Package: Strings related PHP Version: 7.1.0RC6 Block user comment: N Private report: N New Comment: The documentation doesn't say the function gives warnings. Other string functions do not give warnings when $length=0. substr_count should not give warnings. But the change is not documented - not in the substr_count docs (eg, in the Changelog) or in the 7.1 migration guide's "Changed functions" list.
