The file was changed:
... $value=pg_fetch_result($query,1,1);
echo 'all files' . var_dump($value);
...
The resultant web page produces:
bool(false) all files
The php file was changed again:
... $value=pg_fetch_result($query);
echo 'all files' . var_dump($value);
...
The resultant web page produces:
NULL all files
The error log shows:
...PHP Warning: pg_fetch_result(): supplied argument is not a valid
PostgreSQL result resource...
The objective is to learn how to extract data from a database and
