pg_send_query_params — Submits a command and separate parameters to the server without waiting for the result(s)
$connection
, string $query
, array $params
) : boolSubmits a command and separate parameters to the server without waiting for the result(s).
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.
connectionPostgreSQL database connection resource.
queryThe parameterized 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.
paramsAn 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.
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}'");
?>
