# pg_send_execute

(PHP 5 >= 5.1.0, PHP 7)

pg_send_execute — Sends a request to execute a prepared statement with given parameters, without waiting for the result(s)

### 说明

pg_send_execute ( resource `$connection` , string `$stmtname` , array `$params` ) : bool

Sends a request to execute a prepared statement with given parameters, without waiting for the result(s).

This is similar to pg_send_query_params(), but the command to be executed is specified by naming a previously-prepared statement, instead of giving a query string. The function's parameters are handled identically to pg_execute(). Like pg_execute(), it will not work on pre-7.4 versions of PostgreSQL.

### 参数

`connection`

  PostgreSQL database connection resource. When `connection` is not present, the default connection is used. The default connection is the last connection made by pg_connect() or pg_pconnect().

`stmtname`

  The name of the prepared statement to execute. if "" is specified, then the unnamed statement is executed. The name must have been previously prepared using pg_prepare(), pg_send_prepare() or a PREPARE SQL command.

`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

Returns `TRUE` on success, `FALSE` on failure. Use pg_get_result() to determine the query result.

### 范例

Example #1 Using pg_send_execute()

    <?php
      $dbconn = pg_connect("dbname=publisher") or die("Could not connect");

      // Prepare a query for execution
      if (!pg_connection_busy($dbconn)) {
        pg_send_prepare($dbconn, "my_query", 'SELECT * FROM shops WHERE name = $1');
        $res1 = pg_get_result($dbconn);
      }

      // Execute the prepared query.  Note that it is not necessary to escape
      // the string "Joe's Widgets" in any way
      if (!pg_connection_busy($dbconn)) {
        pg_send_execute($dbconn, "my_query", array("Joe's Widgets"));
        $res2 = pg_get_result($dbconn);
      }

      // Execute the same prepared query, this time with a different parameter
      if (!pg_connection_busy($dbconn)) {
        pg_send_execute($dbconn, "my_query", array("Clothes Clothes Clothes"));
        $res3 = pg_get_result($dbconn);
      }

    ?>
