pg_fetch_array
pg_fetch_array returns an array that corresponds to the fetched row (record).
pg_fetch_array is an extended version of pg_fetch_row. In addition to storing the data in the numeric indices (field number) to the result array, it can also store the data using associative indices (field name). It stores both indices by default.
Note:
This function sets NULL fields to the PHP null value.
pg_fetch_array is NOT significantly slower than using pg_fetch_row, and is significantly easier to use.
Parameters
- result
-
An 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, pg_fetch_array will return an array with numerical indices, using PGSQL_ASSOC it will return only associative indices while PGSQL_BOTH, the default, will return both numerical and associative indices.
Return Values
An array indexed numerically (beginning with 0) or associatively (indexed by field name), or both. 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. Fetching from the result of a query other than SELECT will also return false.
