pg_execute
(PHP 5 >= 5.1.0, PHP 7, PHP 8)
pg_execute — Sends a request to execute a prepared statement with given parameters, and waits for the result
Description
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.
The parameters are identical to pg_query_params(), except that the name of a
prepared statement is given instead of a query string.
Parameters
connection-
An PgSql\Connection instance.
When connection is unspecified, the default connection is used.
The default connection is the last connection made by pg_connect()
or pg_pconnect().
WarningAs of PHP 8.1.0, using the default connection is deprecated.
statement_name-
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.
Warning
Elements are converted to strings by calling this function.
Examples
Example #1 Using pg_execute()
<?php
// 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"));
?>
