PDOStatement::execute

(PHP 5 >= 5.1.0, PHP 7, PHP 8, PECL pdo >= 0.1.0)

PDOStatement::execute Executes a prepared statement

Description

publicPDOStatement::execute(?array$params = null): bool

Execute the prepared statement. If the prepared statement included parameter markers, either:

  • PDOStatement::bindParam() and/or PDOStatement::bindValue() has to be called to bind either variables or values (respectively) to the parameter markers. Bound variables pass their value as input and receive the output value, if any, of their associated parameter markers

  • or an array of input-only parameter values has to be passed

Parameters

params

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.

Multiple values cannot be bound to a single parameter; for example, it is not allowed to bind two values to a single named parameter in an IN() clause.

Binding more values than specified is not possible; if more keys exist in params than in the SQL specified in the PDO::prepare(), then the statement will fail and an error is emitted.

Return Values

Returns true on success or false on failure.

Errors/Exceptions

Emits an error with level E_WARNING if the attribute PDO::ATTR_ERRMODE is set to PDO::ERRMODE_WARNING.

Throws a PDOException if the attribute PDO::ATTR_ERRMODE is set to PDO::ERRMODE_EXCEPTION.

Examples

Example #1 Execute a prepared statement with a bound variable and value

<?php

$calories = 150;
$colour = 'gre';
$sth = $dbh->prepare('SELECT name, colour, calories
FROM fruit
WHERE calories < :calories AND colour LIKE :colour'
);
$sth->bindParam('calories', $calories, PDO::PARAM_INT);

$sth->bindValue(':colour', "%$colour%");
$sth->execute();
?>

Example #2 Execute a prepared statement with an array of named values

<?php

$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));

$sth->execute(array(':calories' => $calories, ':colour' => $colour));
?>

Example #3 Execute a prepared statement with an array of positional values

<?php

$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 variables bound to positional placeholders

<?php

$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();
?>

Example #5 Execute a prepared statement using array for IN clause

<?php

$params = array(1, 21, 63, 171);

$place_holders = implode(',', array_fill(0, count($params), '?'));


$sth = $dbh->prepare("SELECT id, name FROM contacts WHERE id IN ($place_holders)");
$sth->execute($params);
?>

Some drivers require to close cursor before executing next statement.
