The seminars will cover different aspects of the CO process that are important for CO trainers to consider before, during and after delivery of trainings. The seminars will be interactive in nature and provide opportunity to showcase and learn from different models and experiences. The participants will also be provided with exclusive insight into new approaches that are developed and tested within the framework of EU-FRANK, and will have the opportunity to try out new ways of working together with new or existing partners.
Kindly note that EU-FRANK encourages participants to take part in and benefit from all three networking events throughout , as well as in-between activities depending on their availability.

PDO inserting recrod to MySQL table
This includes MySQL and compatibles e. While it’s nice not having to rewrite all your queries for every database platform, PDO offers some additional benefits, like simpler syntax than database-specific libraries and easy query parameterization for avoiding SQL injection attacks. As of PHP 5.
PHP is a general-purpose scripting language that is especially suited to web development. Various web template systems , web content management systems , and web frameworks exist which can be employed to orchestrate or facilitate the generation of that response. Additionally, PHP can be used for many programming tasks outside of the web context, such as standalone graphical applications  and robotic drone control. PHP has been widely ported and can be deployed on most web servers on almost every operating system and platform , free of charge.
The PHP language evolved without a written formal specification or standard until , with the original implementation acting as the de facto standard which other implementations aimed to follow. Since , work has gone on to create a formal PHP specification. In addition, PHP version 7.
CRUD Application with PHP, PDO, and MySQL
CodeIgniter has a config file that lets you store your database connection values username, password, database name, etc. You can also set database connection values in the. See below for more details. The name of the class property is the connection name, and can be used while connecting to specify a group name. The default location of the SQLite3 database is in the writable folder.
sudo apt-get install phpmysql, MySQLi, MySQL PDO Search for the line ne in your , uncomment and edit according with 9 – Save all the changes made and restart the Apache service using the following command.
However, this extension was deprecated in So, if you have to switch your project to use another database, PDO makes the process easy. You only have to change the connection string and a few queries. With MySQLi, you will need to rewrite the entire code – queries included. Both support Prepared Statements. Prepared Statements protect from SQL injection, and are very important for web application security. If you need to ensure compatibility with PHP versions prior to 5. PDO require a valid database to connect to.
(The only proper) PDO tutorial
PHP: The Right Way is an easy-to-read, quick reference for PHP popular coding standards, links to authoritative tutorials around the Web and what the contributors consider to be best practices at the present time. There is no canonical way to use PHP. This website will also not tell you which tools to use, but instead offer suggestions for multiple options, when possible explaining the differences in approach and use-case.

There are many tutorials on PDO already, but unfortunately, most of them fail to explain the real benefits of PDO, or even promote rather bad practices. The only two exceptions are phptherightway. As a result, half of PDO’s features remain in obscurity and are almost never used by PHP developers, who, as a result, are constantly trying to reinvent the wheel which already exists in PDO. Unlike those, this tutorial is written by someone who has used PDO for many years, dug through it, and answered thousands questions on Stack Overflow the sole gold PDO badge bearer.
Following the mission of this site , this article will disprove various delusions and bad practices, while showing the right way instead. Although this tutorial is based on mysql driver, the information, in general, is applicable for any driver supported. The abstraction, however, is two-fold: one is widely known but less significant, while another is obscure but of most importance. Everyone knows that PDO offers unified interface to access many different databases.
Although this feature is magnificent by itself, it doesn’t make a big deal for the particular application, where only one database backend is used anyway. And, despite some rumors, it is impossible to switch database backends by changing a single line in PDO config – due to different SQL flavors to do so, one needs to use an averaged query language like DQL.
However, it is not; it is much, much more. PDO abstracts not only a database API, but also basic operations that otherwise have to be repeated hundreds of times in every application, making your code extremely WET. Unlike mysql and mysqli , both of which are low level bare APIs not intended to be used directly but only as a building material for some higher level abstraction layer , PDO is such an abstraction already.
Tony already provided our meet cute with the PDO. What we call the PDO is instead an aggregation of mostly independent processes. During negative cold phases, the pattern reverses. The warm phase of the PDO consists of a boomerang of warmer-than-average seas along the coast of western North America with a pocket of colder-than-average waters in the central North Pacific. The cool phase is the opposite.
The PDO temperature pattern seems to follow multi-year regimes, in which the index is mostly positive warm or negative cool.

During cleanup, a site can be divided into a number of distinct areas depending on its complexity. These areas, called operable units OUs , may address geographic areas, specific problems, or areas where a specific action is required. Examples of typical operable units include construction of a groundwater pump and treatment system or construction of a cap over a landfill. Select an operable unit. After making a selection, press go to filter the table by operable unit.

Edit Report a Bug. I wanted to count number of created statements and number of their executings. It seems MySQL doesn’t support scrollable cursors. I decided to create a singleton wrapper for PDO that ensures only one instance is ever used. It uses PHP 5. This means you can just call it statically from anywhere without having to initiate or define the object. Merge the prepare and execute in one function like a sprintf. And like sprintf, I choose to use unnamed args? When using prepared statements there is no official PDO feature to show you the final query string that is submitted to a database complete with the parameters you passed.
Use this simple function for debugging.
