pg_fetch_row — Get a row as an enumerated array
pg_fetch_row() fetches one row of data from
the result associated with the specified result instance.
Note: This function sets NULL fields to the PHP
nullvalue.
resultAn PgSql\Result instance, returned by pg_query(), pg_query_params() or pg_execute()(among others).
row

omitted or null, the next row is fetched.
mode
An optional parameter that controls how the returned array is indexed.
mode is a constant and can take the following values:
PGSQL_ASSOC, PGSQL_NUM and PGSQL_BOTH.
Using PGSQL_NUM, the function will return an array with numerical indices,
using PGSQL_ASSOC it will return only associative indices
while PGSQL_BOTH will return both numerical and associative indices.
An array, indexed from 0 upwards, with each value
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.
