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
<?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 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(); ?>
