pg_fetch_all
PG_FETCH_ALL(3)PG_FETCH_ALL(3)pg_fetch_all - Fetches all rows from a result as an arraySYNOPSIS
array pg_fetch_all (resource $result)
DESCRIPTION pg_fetch_all(3) returns an array that contains all rows (records) in the result resource.
Note
This function sets NULL fields to the PHP NULL value.
PARAMETERS
o $result
- PostgreSQL query result resource, returned by pg_query(3), pg_query_params(3) or pg_execute(3) (among others).
RETURN VALUES
An array with all rows in the result. Each row is an array of field values indexed by field name.
FALSE is returned if there are no rows in the result, or on any other error.
EXAMPLES
Example #1
PostgreSQL fetch all
<?php
$conn = pg_pconnect("dbname=publisher");
if (!$conn) {
echo "An error occurred.
";
exit;
}
$result = pg_query($conn, "SELECT * FROM authors");
if (!$result) {
echo "An error occurred.
";
exit;
}
$arr = pg_fetch_all($result);
print_r($arr);
?>
The above example will output something similar to:
Array
(
[0] => Array
(
[id] => 1
[name] => Fred
)
[1] => Array
(
[id] => 2
[name] => Bob
)
)
