pg_send_query_params (PHP 5 >= 5.1.0RC1) pg_send_query_params -- Submits a command and separate parameters to the server without waiting for the result(s). Descriptionbool pg_send_query_params ( resource connection, string query, array params )
Submits 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.
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 ValuesReturns 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}'");
