(PHP 5 >= 5.1.0)
pg_send_execute — Sends a request to execute a prepared statement with given parameters, without waiting for the result(s).
说明 bool pg_send_execute ( resource $connection , string $stmtname , array $params )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().
stmtnameThe 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.
paramsAn array of parameter values to substitute for the $1, $2, etc. placeholders in the original prepared query string. The number of elements in the array must match the number of placeholders.
返回值Returns TRUE on success, FALSE on failure. Use pg_get_result() to determine the query result.
范例
Example #1 Using pg_send_execute()
<?php$dbconn=pg_connect("dbname=publisher")ordie("Couldnotconnect");//Prepareaqueryforexecutionif(!pg_connection_busy($dbconn)){pg_send_prepare($dbconn,"my_query",'SELECT*FROMshopsWHEREname=$1');$res1=pg_get_result($dbconn);}//Executethepreparedquery.Notethatitisnotnecessarytoescape//thestring"Joe'sWidgets"inanywayif(!pg_connection_busy($dbconn)){pg_send_execute($dbconn,"my_query",array("Joe'sWidgets"));$res2=pg_get_result($dbconn);}//Executethesamepreparedquery,thistimewithadifferentparameterif(!pg_connection_busy($dbconn)){pg_send_execute($dbconn,"my_query",array("ClothesClothesClothes"));$res3=pg_get_result($dbconn);}?> 参见pg_prepare() - Submits a request to create a prepared statement with the given parameters, and waits for completion. pg_send_prepare() - Sends a request to create a prepared statement with the given parameters, without waiting for completion. pg_execute() - Sends a request to execute a prepared statement with given parameters, and waits for the result.
