INSERT INTO `customers` (`id`, `first_name`, `last_name`, `address`, `email`, `phone`, `country`, `city`) VALUES (107, 'Easter', 'Prebble', '35 Sherman Alley', '71', 'Indonesia', 'Sukasetia') $variable is a name of the php variable to bind with SQL parameter. For a prepared statement using question mark placeholders, this will be the 1-indexed position of the parameter. For a prepared statement using named placeholders, this will be a parameter name of the form :name. $driver_options array holds one or more key=>value pairs to set attribute values for the PDOStatement object that this method returnsīindParam($parameter, $variable, $data_type, $length, $driver_options)īinds a parameter to the specified variable name. $statement must be a valid sql statement. Prepares a statement for execution and returns a statement object. Other functions are already discussed in previous tutorial.
I will only cover PDO functions related to PDO. Let’s have a look at prepared statement functions use in PDO. Now you know what is prepared statement and how it works. PHP PDO Prepared Statement Tutorial for Beginners with Example: You can execute same statement many times with different placholders. Execute: At this stage, Application bind values for the parameters of the statement template and then database execute the statement.Compile: In this step, databases parses the statement and store the result without executing.One is positional placeholder and second is name placeholder. Prepare: At first, application creates a template with placeholders and send to the database.Typically prepared statement works in three steps: It is used almost in every SQL statement (insert, update, select, delete) with certain constant values. It is a feature used to execute same statement repeatedly with high efficiency.
If you don’t know then you should read my previous post. But let’s discuss one more time for PDO.Īt this point I am assuming you know what is PHP PDO. I have already covered prepared statement in mysqli procedural and mysqli object oriented. But PHP PDO true power lies in prepared statement. In my last tutorial, We have seen PHP PDO with example.
