PHP Manual


PDOStatement::execute

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

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. 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.

Return Values

Returns TRUE on success or FALSE on failure.

Changelog

Version Description
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.

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'
);
$sth->bindParam(':calories'$caloriesPDO::PARAM_INT);
$sth->bindParam(':colour'$colourPDO::PARAM_STR12);
$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 = ?'
);
$sth->bindParam(1$caloriesPDO::PARAM_INT);
$sth->bindParam(2$colourPDO::PARAM_STR12);
