  mysqli_stmt_execute

  Executes a prepared statement

Description

Object oriented style

public bool mysqli_stmt::execute();

Procedural style

bool mysqli_stmt_execute(mysqli_stmt statement);

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.

If the statement is UPDATE, DELETE, or INSERT, the total number of affected rows can be determined by using the mysqli_stmt_affected_rows function. Likewise, if the query yields a result set the mysqli_stmt_fetch function is used.

Parameters

stmt

Procedural style only: A statement identifier returned by mysqli_stmt_init.

Return Values

Returns true on success or false on failure.

<?php

mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");

$mysqli->query("CREATE 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]);
}

/* remove table */
$mysqli->query("DROP TABLE myCity");

Procedural style

<?php

mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$link = mysqli_connect("localhost", "my_user", "my_password", "world");

mysqli_query($link, "CREATE 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]);
}

/* remove table */
mysqli_query($link, "DROP TABLE myCity");
