pg_send_query_params()
(PHP 5 >= 5.1.0, PHP 7)
Submits a command and separate parameters to the server without waiting for the result(s)
说明
pg_send_query_params(resource $connection,string $query,array $params): bool
Submits a command and separate parameters to the server without waiting for the result(s).
This is equivalent to pg_send_query() except that query parameters can be specified separately from the$querystring. 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.
参数
- $connection
PostgreSQL database connection resource.
- $query
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.
- $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.
返回值
成功时返回TRUE
,或者在失败时返回FALSE
。
Use pg_get_result() to determine the query result.
范例
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}'"); ?>
