Inhalt: Many successful programmers know more than just a computer language. They also know how to think about solving problems. They use "computational thinking": breaking a problem down into segments that lend themselves to technical solutions. Code Clinic is a series of six courses where lynda.com authors solve the same problems using different programming languages. Here, David Powers works with PHP. David introduces challenges and provides an overview of his solutions in PHP. Challenges include topics such as statistical analysis, searching directories for images, and accessing peripheral devices. Visit other courses in the series to see how to solve the exact same challenges in languages like C#, C++, Java, Python, and Ruby. Umfang: 04:44:35.00

And there's no easy way to send attachments or HTML email with mail(). If you're looking for an alternative, then Swift Mailer is the tool for you. Swift Mailer is free and feature-rich, and it integrates into any web app written in PHP 5 or 7. Swift Mailer offers a flexible and elegant object-oriented approach to sending emails, including HTML email and bulk email. This PHP tutorial guides developers through the process of installing and loading Swift Mailer, and sending emails using SMTP and encrypted SMTP connections. David Powers teaches secure methods that protect users and support MIME standards. He also introduces advanced techniques for sending attachments, personalizing email, and limiting the send rate. Want to see how Swift Mailer solves a real-world programming challenge? Chapter 6 is a case study that shows how to use Swift Mailer to send an email registration form. Umfang: 03:09:12.00
Inhalt: Providing a file from a database in exactly the same format that's requested by the user is an extremely valuable technique. In this course, David Powers shows you how to export data from a database with PHP in a variety of formats, including rich text, CSV, Excel, Word, OpenOffice spreadsheets and documents, and even XML. He introduces tools like PHPExcel and PHPRtfLite that make the job of formatting the data (fonts, headers, columns, and all) easier to manage, and also shows how to embed nontext data like images in your exports. Umfang: 03:42:50.00
Inhalt: PHP persistent sessions allow for communication between the server and client. This allows web applications to remember the identities of visitors as well as any variables or other data. This practical and challenging project-based course will help developers take the data that PHP normally stores in plain text files and write them into a more secure database, where the records can be read and destroyed as needed. Author David Powers helps you set up a SQL database, define classes to open and close sessions, read and write variables, destroy sessions, and manage out-of-date records. The lessons culminate in a short project that uses tokens to recognize returning users in an auto-login scenario. Umfang: 02:41:50.00
Inhalt: Modern websites need to serve high-resolution images to avoid pixelation and blurring on high-pixel-density displays, but at a file size that loads quickly, even on mobile devices. This course shows how to use the GD functions in PHP to resize images and add an optional watermark to them. Author David Powers demonstrates how to calculate the correct scaling ratio by automatically measuring the dimensions and detecting the orientation of a JPEG image. He also explains how to add a watermark using text or, for a more polished result, an image blended with an alpha channel. All the techniques covered are completely nondestructive. Chapter 2 pulls everything together, using a custom PHP class that can batch process multiple images, automatically detect the correct MIME type, generate custom sizes, and add an optional watermark.

Inhalt: PHP is the most popular server-side language used to build dynamic websites, and though it is not especially difficult to use, nonprogrammers often find it intimidating. This introductory workshop from David Powers is designed to change that by teaching you PHP through a series of clear, focused, easy-to-follow lessons. After briefly explaining what PHP is and how it integrates with HTML, David introduces the features of the language. He covers variables, conditional statements, calculations, loops, and functions, as well as server-side includes and error handing, in a series of hands-on exercises. He then moves to a larger project that involves building a script to validate and email user input from an online form. By following along, you'll come to understand the value of creating reusable code, the importance of PHP security, and how to deal with multiple-choice form fields. Umfang: 06:57:40.00
Inhalt: Most PHP programmers will eventually run into an XML data set. The easiest way to deal with this data is using the SimpleXML extension for PHP. In this course, David Powers walks through loading and extracting data from a basic XML document, working with namespaces, and editing XML elements and attributes with SimpleXML and the XPath query language. He also shows practical uses for XML, such as displaying text as well as images from an RSS feed, and the process for generating new XML documents from scratch with SimpleXML. Umfang: 02:20:45.00
Inhalt: MySQL is one of the most widely used database systems for dynamic websites and content management systems. And phpMyAdmin is the most common method of administering a MySQL database, included in many CMSs as well as the XAMPP and MAMP testing environments. Updated for phpMyAdmin 4.5, this introductory course shows designers and developers how to set up local user accounts, create a database, and design tables. Author David Powers also explains how to import data from CSV files, spreadsheets, and SQL dump files, and how to export data for backup or to transfer to another database. You'll also learn how to run database queries within its intuitive form-based interface, and monitor server performance. Umfang: 05:26:19.00
Inhalt: The Standard PHP Library (SPL) is a collection of useful classes for traversing, filtering, and sorting data and objects. One of its main features is the iterator, which provide easy access to arrays, trees, and directory listings. In this course, David Powers reviews using these iterators to explore the file system, and combining iterators in order to edit and manage specific types of files. He'll show how to load XML and JSON data, convert arrays into nested lists, and work with data structures such as doubly linked lists, queues, and heaps. Start learning how to put SPL into practice, and extend the power of your PHP applications. Umfang: 03:24:29.00
