PDOStatement->execute()
(PHP 5 >= 5.1.0, PECL pdo:0.1-1.0.3)
PDOStatement->execute() — Executes a prepared statement
说明
Execute the prepared statement. If the prepared statement included parameter markers, you must either:
call PDOStatement->bindParam() to bind PHP variables to the parameter markers: bound variables pass their value as input and receive the output value, if any, of their associated parameter markers
or pass an array of input-only parameter values
参数
- input_parameters
-
An array of values with as many elements as there are bound parameters in the SQL statement being executed.
You cannot bind multiple values to a single parameter; for example, you cannot bind two values to a single named parameter in an IN() clause.
返回值
如果成功则返回 TRUE，失败则返回 FALSE。
范例
Example#1 Execute a prepared statement with bound variables
<?php
/* Execute a prepared statement by binding PHP variables */
$calories = 150;
$colour = 'red';
$sth = $dbh->prepare('SELECT name, colour, calories
FROM fruit
WHERE calories < :calories AND colour = :colour');
$sth->bindParam(':calories', $calories, PDO::PARAM_INT);
$sth->bindParam(':colour', $colour, PDO::PARAM_STR, 12);
$sth->execute();
?>
Example#2 Execute a prepared statement with an array of insert values (named parameters)
<?php
/* Execute a prepared statement by passing an array of insert values */
$calories = 150;
$colour = 'red';
$sth = $dbh->prepare('SELECT name, colour, calories
FROM fruit
WHERE calories < :calories AND colour = :colour');
$sth->execute(array(':calories' => $calories, ':colour' => $colour));
?>
Example#3 Execute a prepared statement with an array of insert values (placeholders)
<?php
/* Execute a prepared statement by passing an array of insert values */
$calories = 150;
$colour = 'red';
$sth = $dbh->prepare('SELECT name, colour, calories
FROM fruit
WHERE calories < ? AND colour = ?');
$sth->execute(array($calories, $colour));
?>
Example#4 Execute a prepared statement with question mark placeholders
<?php
/* Execute a prepared statement by binding PHP variables */
$calories = 150;
$colour = 'red';
$sth = $dbh->prepare('SELECT name, colour, calories
FROM fruit
WHERE calories < ? AND colour = ?');
$sth->bindParam(1, $calories, PDO::PARAM_INT);
$sth->bindParam(2, $colour, PDO::PARAM_STR, 12);
$sth->execute();
?>
