1. Using the `` tags: The most common way to embed PHP code in an HTML page is by using the `` tags. You can place your PHP code within these tags anywhere in the HTML document.
2. Using short tags: You can also use short tags ` ?>` to embed PHP code in an HTML page. However, it is recommended to use the full `` tags for better compatibility.
3. Using echo statement: You can use the `echo` statement to output PHP code directly within the HTML code. For example, `echo "Hello, World!";` will output "Hello, World!" in the HTML page.
4. Using PHP include function: You can use the `include` function to include an external PHP file within an HTML page. This allows you to separate your PHP code into different files for better organization.
5. Using PHP within HTML attributes: You can embed PHP code within HTML attributes by using the `` tags. For example, `
` will output an image with the specified URL.
6. Using PHP within script tags: You can embed PHP code within `
```
3. External File: PHP code can be placed in an external file with a `.php` extension, and then included into the HTML page using the `include` or `require` statements. For example:
```html
```
4. HTML Template: PHP can be used to generate dynamic HTML code using template engines such as Smarty or Twig. The PHP template files will have a `.tpl` or `.html.twig` extension, and they can be rendered into HTML using the template engine's functions.
