PDOStatement::execute --
Executes a prepared statement
Beschreibung
bool
PDOStatement::execute ( [array input_parameters] )
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
Parameter Liste
- 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.
Rückgabewerte
Gibt bei Erfolg TRUE zurück, im Fehlerfall FALSE.
Beispiele
Beispiel 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();
?>

Beispiel 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));
?>

Beispiel 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));
?>

Beispiel 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();
