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.
PostgreSQL query result resource, returned by pg_query(), pg_query_params() or pg_execute() (among others).
Row number in result to fetch. Rows are numbered from 0 upwards. If omitted or NULL
, the next row is fetched.
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.
<?php $conn = pg_connect("dbname=publisher"); if (!$conn) { echo "An error occurred.\n"; exit; } $result = pg_query($conn, "SELECT id, author, email FROM authors"); if (!$result) { echo "An error occurred.\n"; exit; } while ($row = pg_fetch_assoc($result)) { echo $row['id']; echo $row['author']; echo $row['email']; } ?>
