pg_executeSends a request to execute a prepared statement with given parameters, and waits for the result


pg_execute(PgSql\Connection $connection = ?, string $stmtname, array $params): PgSql\Result|false

Sends a request to execute a prepared statement with given parameters, and waits for the result.

pg_execute() is like pg_query_params(), but the command to be executed is specified by naming a previously-prepared statement, instead of giving a query string. This feature allows commands that will be used repeatedly to be parsed and planned just once, rather than each time they are executed. The statement must have been prepared previously in the current session. pg_execute() is supported only against PostgreSQL 7.4 or higher connections; it will fail when using earlier versions.

The parameters are identical to pg_query_params(), except that the name of a prepared statement is given instead of a query string.

Bağımsız Değişkenler


PgSql\Connection nesnesi. bağlantı belirtilmemişse öntanımlı bağlantı kullanılır. Öntanımlı bağlantı pg_connect() veya pg_pconnect() işleviyle kurulmuş son bağlantıdır.


PHP 8.1.0 ve sonrasında, öntanımlı bağlantının kullanımı önerilmemektedir.


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.


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.


Elements are converted to strings by calling this function.

Örnek 1 Using pg_execute()

// Connect to a database named "mary"
$dbconn = pg_connect("dbname=mary");

// Prepare a query for execution
$result = pg_prepare($dbconn, "my_query", 'SELECT * FROM shops WHERE name = $1');

// Execute the prepared query. Note that it is not necessary to escape
// the string "Joe's Widgets" in any way
$result = pg_execute($dbconn, "my_query", array("Joe's Widgets"));

// Execute the same prepared query, this time with a different parameter
$result = pg_execute($dbconn, "my_query", array("Clothes Clothes Clothes"));

I am not 100% sure in this, but pg_exec() could return 0 as Connection ID.

because of that i change some of my code like this:

$dbres = pg_exec($SQL);

if ($dbres === false){
        echo "DB is down";
        //do something
