From 5ca1e271f9023b41b613313745bc700dc15d802f Mon Sep 17 00:00:00 2001 From: Eli Schwartz Date: Wed, 12 Feb 2020 15:16:37 -0500 Subject: Fix PHP 7.4 warnings If a db query returned NULL instead of an array, then accessing $row[0] now throws a warning. The undocumented behavior of evaluating to NULL is maintained, and we want to return NULL anyway, so add a check for the value and fall back on the default function return type.
