mysqli_stmt::execute -- mysqli_stmt_execute — Executes a prepared statement

说明

面向对象风格

public mysqli_stmt::execute(?array $params = null): bool

过程化风格

mysqli_stmt_execute(mysqli_stmt $statement, ?array $params = null): bool

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. If the query yields a result set, it can be fetched using mysqli_stmt_get_result() function or by fetching it row by row directly from the statement using mysqli_stmt_fetch() function.

参数

statement

仅以过程化样式：由 mysqli_stmt_init() 返回的 mysqli_stmt 对象。

params

An optional list array with as many elements as there are bound parameters in the SQL statement being executed. Each value is treated as a string.

返回值

成功时返回 true， 或者在失败时返回 false。

错误／异常

If mysqli error reporting is enabled (MYSQLI_REPORT_ERROR) and the requested operation fails, a warning is generated. If, in addition, the mode is set to MYSQLI_REPORT_STRICT, a mysqli_sql_exception is thrown instead.

更新日志

版本 说明
8.1.0 The optional params parameter has been added.

示例

示例 #1 Execute a prepared statement with bound variables

面向对象风格

<?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]);
}

过程化风格

<?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]);
}

以上示例会输出：

Stuttgart (DEU,Baden-Wuerttemberg)
Bordeaux (FRA,Aquitaine)

示例 #2 Execute a prepared statement with an array of values

面向对象风格

<?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 (?,?,?)');

/* Execute the statement */
$stmt->execute(['Stuttgart', 'DEU', 'Baden-Wuerttemberg']);

/* 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]);
}

过程化风格

<?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 (?,?,?)');

/* Execute the statement */
mysqli_stmt_execute($stmt, ['Stuttgart', 'DEU', 'Baden-Wuerttemberg']);

/* 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]);
}

以上示例会输出：

Stuttgart (DEU,Baden-Wuerttemberg)
