Executes a prepared statement
Description
Object-oriented style
public bool mysqli_stmt::execute(array|null params= =null);
Procedural style
bool mysqli_stmt_execute(mysqli_stmt statement,
array|null params= =null);
Executes previously prepared statement. The statement must be
successfully prepared prior to execution, using either the
mysqli_prepare
or
mysqli_stmt_prepare
function, or by passing the second argument to
mysqli_stmt::__construct

function or by fetching it row by row directly from the
statement using
mysqli_stmt_fetch
function.

Examples
Example 3.83 Execute a prepared statement with bound variables
Object-oriented style
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
$mysqli->query("CREATE TEMPORARY TABLE myCity LIKE City");
/* Prepare an insert statement */
$stmt = $mysqli->prepare("INSERT INTO myCity (Name, CountryCode, District) VALUES (?,?,?)");
/* Bind variables to parameters */
$stmt->bind_param("sss", $val1, $val2, $val3);
$val1 = 'Stuttgart';
$val2 = 'DEU';
$val3 = 'Baden-Wuerttemberg';
/* Execute the statement */
$stmt->execute();
$val1 = 'Bordeaux';
$val2 = 'FRA';
$val3 = 'Aquitaine';
/* Execute the statement */
$stmt->execute();
/* Retrieve all rows from myCity */
$query = "SELECT Name, CountryCode, District FROM myCity";
$result = $mysqli->query($query);
while ($row = $result->fetch_row()) {
printf("%s (%s,%s)\n", $row[0], $row[1], $row[2]);
}
Procedural style
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
mysqli_query($link, "CREATE TEMPORARY TABLE myCity LIKE City");
/* Prepare an insert statement */
$stmt = mysqli_prepare($link, "INSERT INTO myCity (Name, CountryCode, District) VALUES (?,?,?)");
/* Bind variables to parameters */
mysqli_stmt_bind_param($stmt, "sss", $val1, $val2, $val3);
$val1 = 'Stuttgart';
$val2 = 'DEU';
$val3 = 'Baden-Wuerttemberg';
/* Execute the statement */
mysqli_stmt_execute($stmt);
$val1 = 'Bordeaux';
$val2 = 'FRA';
$val3 = 'Aquitaine';
/* Execute the statement */
mysqli_stmt_execute($stmt);
/* Retrieve all rows from myCity */
$query = "SELECT Name, CountryCode, District FROM myCity";
$result = mysqli_query($link, $query);
while ($row = mysqli_fetch_row($result)) {
printf("%s (%s,%s)\n", $row[0], $row[1], $row[2]);
}
The above examples will output:
Stuttgart (DEU,Baden-Wuerttemberg) Bordeaux (FRA,Aquitaine)
