pg_send_query - Sends asynchronous query

SYNOPSIS
bool pg_send_query (resource $connection, string $query)
DESCRIPTION
pg_send_query(3) sends a query or queries asynchronously to the $connection. Unlike pg_query(3), it can send multiple queries at once to PostgreSQL and get the results one by one using pg_get_result(3). Script execution is not blocked while the queries are executing. Use pg_connection_busy(3) to check if the connection is busy (i.e. the query is executing). Queries may be cancelled using pg_cancel_query(3). Although the user can send multiple queries at once, multiple queries cannot be sent over a busy connection. If a query is sent while the connection is busy, it waits until the last query is finished and discards all its results.
PARAMETERS
o $connection - PostgreSQL database connection resource. o $query - The SQL statement or statements to be executed. Data inside the query should be properly escaped.
RETURN VALUES
Returns TRUE on success or FALSE on failure. Use pg_get_result(3) to determine the query result.
EXAMPLES
Example #1 pg_send_query(3) example <?php $dbconn = pg_connect("dbname=publisher") or die("Could not connect"); if (!pg_connection_busy($dbconn)) { pg_send_query($dbconn, "select * from authors; select count(*) from authors;"); } $res1 = pg_get_result($dbconn); echo "First call to pg_get_result(): $res1 "; $rows1 = pg_num_rows($res1); echo "$res1 has $rows1 records "; $res2 = pg_get_result($dbconn); echo "Second call to pg_get_result(): $res2 "; $rows2 = pg_num_rows($res2); echo "$res2 has $rows2 records "; ?> The above example will output: First call to pg_get_result(): Resource id #3 Resource id #3 has 3 records Second call to pg_get_result(): Resource id #4 Resource id #4 has 1 records
