PHP to TPL
In PHP web design, what is a tpl file?
When a PHP web application parses the template file, TPL is a generic text file that contains user-defined variables that are permitted to be overridden by user-defined output content. These are used as a reference file by web applications that use the server script PHP (but are not limited to). The main content of a.tpl file is template code, which is mostly plain HTML text. Since the tpl language is stored as plain text in tpl files, it can be edited with simple text editors.
Usage in the following circumstances:
While it may appear to be simple to incorporate PHP codes into HTML, it is not a good code management technique because it is difficult for the design team to maintain files with a combination of PHP and HTML tags equally. Model codes are used to distinguish the specification from the development in this situation.
Template files protect PHP by providing a much more user-friendly tag-based syntax. To manage a template file, no PHP knowledge is needed. It is usually more important to web designers than it is to PHP developers.
There are a few popular places where template files are placed.
• Code reusability, where the same specification is used by several parties. An online course site, for example, where colleges create their own page where they can post their own courses.
• CMS (Content Management Systems).
• A project in which the web design and PHP development teams are not the same.
To use web design with a prototype with PHP, we'll use the Smarty platform. Smarty is a free open-source platform that uses simple tag-based template statements to generate clean, maintainable presentation code for PHP web applications.
The following are the steps to get started with Smarty in Apache.
1. Go to https://github.com/smarty-php/smarty/archive/master.zip to get the most recent version of Smarty.
2. Unzip the file and add the template c and cache folders.
3. Add include path=”.;path to where the libs folder is present in step 3′′ to the php.ini file.
4. Create a smarty folder in htdocs(root) and copy the folder configs from step 3's original downloaded folder.
5. Create a new folder called templates and a PHP file called index.php in it.
6. In the templates folder, place the index.tpl template.
As a result, one can write all of his template code for handling presentations in templates/index.tpl, and all of his php code for handling data processing in index.php.
Benefits of using a tpl file include:
• Customizability in terms of production.
• A neat and tidy code presentation.
• For programmers and designers, rapid production or release is important.
• It's quick and easy to keep up with.
• Code that is easily re-usable
• PHP isolation for protection.
• Using design files with PHP in a practical way: The template files used by Phorum are an example of.tpl files in PHP. It's an open source message board framework that runs on PHP and MySQL. The.tpl files display data created dynamically by Phorum, such as message information, search-related results, and private message strings.
The template language in.tpl files is a special format that usually consists of HTML and basic Phorum template statements. These statements support integers, strings, PHP constants, and template variables, among other data types.
• The importance of tpl files in Phorum: In addition to using TPL files for storing basic template code, Phorum uses.php files if they are put in the template directory and called with the required basename. A TPL file primarily contains style details and other information about the PHP application's web pages.
• When Phorum displays the header footer template, it first looks for header.php in the template directory, then looks for header.tpl if that file does not exist. It's not all about Phorum. .tpl is used by many other parsers and, increasingly, custom solutions. Also, because.tpl files are very robust, PHP codes can be placed within them if desired. OpenCart and vBulletin are good examples of this, as can be seen in the.tpl files, which contain PHP code. That is why NGINX and several other servers come pre-configured with safeguards that prevent unauthorized access to tpl files.
What Is a PHP File and How Do I Use It?
You'll be generating and coding files with the.php extension while learning the PHP scripting language. What is a PHP file, exactly?
A PHP file, in general, is a plain-text file containing code written in the PHP programming language. The code written in the PHP file is installed on the server since PHP is a server-side (back-end) scripting language. When a web page is submitted to the client side for rendering in the user browser, the PHP engine on the web server translates all PHP content to HTML, resulting in a web page that only includes HTML code.
In reality, a PHP file may include plain text, HTML tags, or PHP syntax code. When you visit a PHP-powered website, your request is sent to the server, where the PHP engine interprets and executes the PHP code. The PHP code is translated to HTML and combined with the rest of the file's plain text and HTML. After the page has completed, the completed HTML is submitted to the client.
You'll never see the original PHP code in the root of any PHP file in a browser since the server has already executed it and converted it to HTML.
That's how a PHP file works in general. In the following section, we'll look at an example of a PHP file.
A PHP File's Structure
We'll quickly go through the layout of a PHP file in this section. Take a look at this PHP file as an example:
2 Echo “<b>Hello World</b>”;
The code enclosed by the?php and?> tags in the preceding example is a PHP script. A PHP file can also contain non-PHP code, such as plain text or HTML tags, as we mentioned in the previous section. On the server, the code enclosed by the?php and?> tags is executed.
Following the execution of the PHP code in the preceding example, the output looks like this:
1 <b>Hello World</b>
In fact, the structure of a PHP file may look like:
02 //PHP code
04 <div>other HTML tags</div>
05 Plain text
06 <?php // more PHP code ?>
07 <p>more HTML</p>
As you can see, a PHP file can contain both code and HTML as well as plain text.
