(PHP 5 >= 5.1.0, PECL pdo >= 0.1.0)
PDOStatement->execute — Executes a prepared statement
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
An array of values with as many elements as there are bound parameters in the SQL statement being executed. All values are treated as PDO::PARAM_STR.
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.
You cannot bind more values than specified; if more keys exist in input_parameters than in the SQL specified in the PDO::prepare(), then the statement will fail and an error is emitted.
成功时返回 TRUE， 或者在失败时返回 FALSE.
| 版本 | 说明 |
|---|---|
| 5.2.0 | The keys from input_parameters must match the ones declared in the SQL. Before PHP 5.2.0 this was silently ignored. |
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();
?>

Some drivers require to close cursor before executing next statement.
