php-src/ext/odbc/php_odbc.c
Calvin Buckley 5a2b251610 Fix persistent procedural ODBC connections not getting closed 
Like oci8, procedural ODBC uses an apply function on the hash list to
enumerate persistent connections and close the specific one. However,
this function take zvals, not resources. However, it was getting casted
as such, causing it to interpret the pointer incorrectly. This could
have caused other issues, but mostly manifested as failing to close the
connection even fi it matched.

The function now takes a zval and gets the resource from that. In
addition, it also removes the cast of the function pointer and moves
casting to the function body, to avoid possible confusion like this in
refactors again. It also cleans up style and uses constants in the
function body.

Closes GH-12132
