It looks choose the resource of the error comes from $section no being an array sometimes, but it wouldn"t pains to additionally account for selection keys top top $section not being collection when it is an array.
PHP"s Null Coalescing Operator is valuable here for accounting for the non-existing range key.
Example of readjusted line:
This consists the instance when fields is not set or null. The ?? operator will return the left operand if it is set and is no null, otherwise it will return the best operand of false i beg your pardon is definitely not one array:
if (!is_array($section<"fields"> ?? false)) continue;This will cover the case where $section chin is null and not an array:
if (!is_array($section) || !is_array($section<"fields"> ?? false)) continue;Example use of Null Coalescing Operator
"Some Value">;// The vital "baz" does not exist$baz = $foo<"baz"> ?? "nothing";// The range offset error will certainly be prevented.// Output will be: "nothing"echo $baz; Example straight From php.net
