mysqli

Represents a connection between PHP and a MySQL database.
query

mysqli::query — mysqli_query — Performs a query on the database
close

mysqli::close — mysqli_close — Closes a previously opened database connection
prepare

mysqli::prepare — mysqli_prepare — Prepare an SQL statement for execution
bind_param

mysqli_stmt::bind_param — mysqli_stmt_bind_param — Binds variables to a prepared statement as parameters
execute

mysqli_stmt::execute — mysqli_stmt_execute — Executes a prepared Query
PDO

Represents a connection between PHP and a database server.
setAttribute

PDO::setAttribute — Set an attribute
fetchColumn

PDOStatement::fetchColumn — Returns a single column from the next row of a result set
catch

PHP 5 has an exception model similar to that of other programming languages. An exception can be thrown, and caught (“catched”) within PHP. Code may be surrounded in a try block, to facilitate the catching of potential exceptions. Each try must have at least one corresponding catch or finally block.
