pg_fetch_assoc
Fetch a row as an associative array
Description
arrayfalse pg_fetch_assoc(PgSql\Result $result
, intnull $row
= null
)
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
-
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.
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.
