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 Row number in result to fetch. Rows are numbered from 0 upwards. If 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.
