# PDOStatement->execute

(PHP 5 >= 5.1.0, PECL pdo:0.1-1.0.3)

PDOStatement->execute — Executes a prepared statement

### Description

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

### Parameters

`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.

### Return Values

Returns `TRUE` on success or `FALSE` on failure.

### Examples

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();
?>`
