The primary difference between plugins and themes lies in their purpose and functionality within a WordPress website.

WordPress Themes:

WordPress themes are primarily responsible for the visual appearance of your website. They control the design, layout, colors, navigation, and everything else that contributes to the overall look of your site. It’s worth noting that a WordPress site can only have one theme active at a time.

Themes can be categorized into two types: multipurpose and niche. Multipurpose themes offer customization options for a wide range of site types, while niche themes are designed for specific purposes, such as business or photography themes.

WordPress Plugins:

Plugins are designed to add new features and functionalities to your website. While themes affect what your site looks like, plugins affect what it can do. This means plugins can’t be as easily summarized, since there are solutions for almost any functionality you can imagine.

For instance, Contact Form 7 is a plugin that lets you build customizable forms and embed them on your pages. Other plugins, such as Jetpack or Wordfence, provide a variety of helpful tools and functionalities.

In addition to server-side scripting, other crucial topics in PHP for building websites include:

1. HTML and CSS:

HTML and CSS are the fundamental building blocks of web development. PHP is often used in conjunction with HTML and CSS to build dynamic web pages.

2. Database connectivity:

PHP provides built-in support for connecting to several popular databases such as MySQL, PostgreSQL, and SQLite. Understanding how to establish a connection, perform CRUD (create, read, update, delete) operations, and handle errors and exceptions related to database connectivity is crucial for building scalable and efficient web applications.

3. Session management:

Sessions allow you to store user-specific data across multiple pages of a web application. PHP provides built-in support for managing sessions, which can help create a more personalized user experience.

4. Content management systems (CMS):

Content management systems such as WordPress and Drupal are built using PHP. Understanding how to use and customize these systems can help you build websites quickly and efficiently.

5. Security:

Security is an essential aspect of web development. PHP provides several built-in functions and tools for handling user input, validating input, and preventing SQL injection attacks.

Overall, while server-side scripting is a crucial topic in PHP for building websites, mastering other essential topics such as HTML and CSS, database connectivity, forms and user input, content management systems, and security can help you become a proficient PHP developer and build robust and secure web applications.

Artificial intelligence (AI) is creating massive ripples around the world. For some, it enhances customer experiences; for others, it reduces costs through automation. AI analyzes large data sets with ease, enabling better decision making and uncovering new business opportunities.

Now, it’s also working its way into content management. We’ve already seen examples of AI powering content processing and analysis, and it’s set to become a crucial part of the content generation process.

My company, Contentstack, was one of the first headless content management systems (CMS) to embed AI into its editor experience. Turnkey integrations with IBM Watson, Salesforce Einstein and MonkeyLearn have allowed our customers to leverage AI to create highly personalized digital experiences that go beyond standard demographics and traditional audience segmentation.

Here are just a few ways AI has already begun to impact today’s content management systems:

1. Text intelligence and analysis: AI can already analyze the tone and sentiment of content and suggest if it is suitable for the intended audience. IBM Watson and MonkeyLearn, for example, have developed intelligent systems that leverage natural language processing (NLP) to provide text intelligence services such as language detection, keyword extraction, profanity detection, news categorization, sentiment analysis and so on.

2. Automatic image tagging and categorization: Image tagging is a daunting and mundane, yet extremely important task. This is especially true for e-commerce platforms or royalty-free stock image sites where hundreds of images are uploaded every day. Success depends on displaying results that are both accurate and highly relevant to the searched keyword.

Until recently, automatic image recognition lacked the precision required for the task. However, the next generation of AI-powered image recognition and tagging tools can analyze images in seconds. Many platforms have started embedding these tools for keyword metadata enhancement, and this trend is likely to accelerate.  

3. Voice-controlled platforms and services: AI-assisted voice services have gone from fantasy to reality in less than a decade. Services such as Apple’s Siri, Google Home, Amazon Echo (Alexa) and Microsoft’s Cortana are increasing the productivity of millions of people every day. Many content management platforms provide voice-assisted services, including voice-to-text and voice commands.

4. Personalized content and marketing: AI algorithms are capable of tracking individual users’ behavioral patterns and can use such data to predict future needs and expectations. This capability is helping marketers deliver personalized content to boost customer engagement, satisfaction and revenue.

Targeted advertising based on demographics and past behavior is the tip of the iceberg; individualized offers, highly-relevant product recommendations and dynamic websites that serve pages based on the user’s past purchase data and most recent actions are becoming table stakes in many industries.   

5. Accelerated content creation: Artificial intelligence cannot yet create completely original stories. However, its capabilities, including those of NLP and natural language generation (NLG), can help accelerate the process of content generation. Some of the areas where AI is already helping is content translation, video and audio transcription, auto-tagging and metadata creation, grammar check and content protection.

The Future Of AI And CMS

Here are just some of the ways in which AI is likely to change tomorrow’s CMS platforms: 1. Advanced analytics: As companies become more customer-centric, the analytics that your CMS provides will likely become more sophisticated. Enriched with data on past behavior, your CMS will be able to understand the entire customer journey and may be able to predict the type of content that leads to the most engagement and the highest likelihood of a conversion.2. Interaction with other AI systems: We have seen how voice-activated devices (e.g., smart speakers) connect with other smart devices (e.g., LED lights, air-conditioners, etc.). With the pace of development across the AI space, we are not far away from the day when your CMS will be able to connect to these devices. Ultimately, AI will be able to optimize not just the content, but also the user interface (UI) and user experience (UX) for the best possible customer experience and satisfaction.

3. Real-time SEO recommendations: Imagine a CMS that is capable of identifying — in real time — whether your content is better than your competitors’ in terms of search engine optimization (SEO). It might highlight terms that you should or shouldn’t use and provide recommendations to get listed on the first page of target search results.

4. Intelligent digital asset management: When it comes to AI for digital assets, content management systems don’t have much to offer right now except for automated image tagging and categorization. However, with new sophisticated AI tools, you may one day be able to offer intelligent services like searching content within videos, automatic (and accurate) voice-to-text transcription of video content or identifying moments of high interest in videos.

Preparing For The Future

In many ways, AI and CMS are a match made in heaven — at least, for end users of a CMS.

Amidst all the excitement surrounding AI, one thing is clear: There is a lot of real-time development happening, and no single vendor or solution is set to dominate the market. In theory, AI can be applied to almost any domain, but since it learns from past behavior, a special-purpose AI is typically more useful than a generalized one.

For a CMS vendor to limit themselves to embedding a single AI (built in-house or not) into its product suite is foregoing the benefits of all the innovation taking place. Instead, CMS products should be architected to take advantage of any and all AI as they become useful and emerge as best-in-class for a particular domain.

Rather than competing against the global leaders in AI development, CMS vendors should view them as partners and focus their efforts on delivering a seamless user experience through both flexible and extensible product design. CMS developers, meanwhile, should look for CMS architectures that don’t limit what AI they can tap into for the applications and experiences they are creating.

In the world of CMS, the days of the single-vendor suite may be over, but the area of the pluggable CMS AI has just begun.
