pg_fetch_assoc
Fetch a row as an associative array
Description
array pg_fetch_assoc
( resource $result
[, int $row
] )
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
-
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.
Examples
Example #1 pg_fetch_assoc example
<?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'];
}
