pg_fetch_assoc — Fetch a row as an associative array
$result
[, int $row
] ) : arraypg_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
NULLvalue.
pg_fetch_assoc() is NOT significantly slower than using pg_fetch_row(), and is significantly easier to use.
resultPostgreSQL 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.
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.
Example #1 pg_fetch_assoc() example
<?php
$conn = pg_connect("dbname=publisher");

}
$result = pg_query($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'];
