pg_fetch_assoc
(PHP 4 >= 4.3.0, PHP 5)
pg_fetch_assoc — Fetch a row as an associative array
Description
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 NULL value.
pg_fetch_assoc() is NOT significantly slower than using pg_fetch_row(), and is significantly easier to use.
Parameters
- result
-
PostgreSQL query result resource, 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, next row is fetched.
Return Values
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.
