pg_fetch_row — Get a row as an enumerated array

Description

pg_fetch_row(PgSql\Result $result, ?int $row = null, int $mode = PGSQL_NUM): array|false

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 null value.

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, 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.

Return Values

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.

Changelog

Version	Description
8.1.0	The `result` parameter expects an PgSql\Result instance now; previously, a resource was expected.
