PHP is a programming language widely used for web development. One of its main features is the ability to be integrated with HTML, allowing the creation of dynamic and interactive pages.
To insert PHP code into an HTML file, it is necessary to use the <?php tag to start the PHP code block and the ?> tag to end it. Between these tags, you can write any valid PHP code.
For example, suppose you want to display the current date in an HTML page. You can use the following PHP code:
<?php
echo date('d/m/Y');
?>
This code will display the current date in day/month/year format.
In addition to displaying information, it is possible to use PHP to process forms, access databases, send emails, among other features. For this, it is necessary to write the corresponding PHP code and integrate it with the HTML of the page.

A common way to integrate PHP with HTML is to use loops and conditionals to dynamically generate content. For example, suppose you have an array of the names and ages of several people and you want to display this information in an HTML table. You can use the following PHP code:
<table>
<tr>
<th>Name</th>
<th>Age</th>
</tr>
<?php foreach($persons as $person) { ?>
<tr>
<td><?php echo $person['name']; ?></td>
<td><?php echo $person['age']; ?></td>
</tr>
<?php } ?>
</table>
In this code, the foreach loop is used to loop through the $people array and generate a row in the table for each person. The table's HTML code is interspersed with PHP code that displays each person's name and age.
In summary, the insertion of PHP in HTML allows you to create dynamic and interactive web pages, using advanced programming resources. For this, it is necessary to know the syntax of PHP and know how to integrate it with the HTML of the page.
