pg_send_query_params — Submits a command and separate parameters to the server without waiting for the result(s).

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.

connection

PostgreSQL database connection resource.

The 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.

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.

成功时返回 TRUE， 或者在失败时返回 FALSE。

Use pg_get_result() to determine the query result.
