PDOStatement->execute()

Executes a prepared statement ()

PDOStatement {
  bool 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 1780. 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 1781. 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 1782. 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 1783. 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();
?>
