pg_fetch_assoc — Fetch a row as an associative array
pg_fetch_assoc() returns an associative array that corresponds to the fetched row (records).
pg_fetch_assoc() is equivalent to calling pg_fetch_array() with PGSQL_ASSOC as the optional third parameter. It only returns an associative array. If you need the numeric indices, use pg_fetch_row().
Note: This function sets NULL fields to the PHP
nullvalue.
pg_fetch_assoc() is NOT significantly slower than using pg_fetch_row(), and is significantly easier to use.
resultAn PgSql\Result instance, returned by pg_query(), pg_query_params() or pg_execute()(among others).
row Row number in result to fetch. Rows are numbered from 0 upwards. If omitted or null, the next row is fetched.
An array indexed associatively (by field name). Each value in the array is represented as a string. Database NULL values are returned as null.
false is returned if row exceeds the number of rows in the set, there are no more rows, or on any other error.
| Version | Description |
|---|---|
| 8.1.0 | The result parameter expects an PgSql\Result instance now; previously, a resource was expected. |

}
while ($row = pg_fetch_assoc($result)) {
echo $row['id'];
echo $row['author'];
