pg_fetch_assoc
(PHP 4 >= 4.3.0, PHP 5, PHP 7)
pg_fetch_assoc — Fetch a row as an associative array
Description
pg_fetch_assoc
( resource $result
[, int $row
] ) : array
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 tothe 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 or
NULL
, the 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.
