pg_send_query_params
(PHP 5 >= 5.1.0)
pg_send_query_params — Submits a command and separate parameters to the server without waiting for the result(s).
Description
bool pg_send_query_params
( resource $connection
, string $query
, array $params
)
This is equivalent to pg_send_query() except that query
parameters can be specified separately from the
query
string. The function's parameters are
handled identically to pg_query_params(). Like
pg_query_params(), it will not work on pre-7.4 PostgreSQL
connections, and it allows only one command in the query string.
Parameters
-
connection
-
PostgreSQL database connection resource.
-
query
-
The parameterised SQL statement. Must contain only a single statement.
(multiple statements separated by semi-colons are not allowed.) If any parameters
are used, they are referred to as $1, $2, etc.
-
params
-
An array of parameter values to substitute for the $1, $2, etc. placeholders
in the original prepared query string. The number of elements in the array
must match the number of placeholders.
Return Values
Returns TRUE on success or FALSE on failure.
Use pg_get_result() to determine the query result.
Examples
Example #1 Using pg_send_query_params()
<?php
$dbconn = pg_connect("dbname=publisher") or die("Could not connect");
// Using parameters. Note that it is not necessary to quote or escape
// the parameter.
pg_send_query_params($dbconn, 'select count(*) from authors where city = $1', array('Perth'));
// Compare against basic pg_send_query usage
$str = pg_escape_string('Perth');
pg_send_query($dbconn, "select count(*) from authors where city = '${str}'");
?>
