How to use PHP echo to display the title of a web page

PHP echo is a language construct that outputs one or more strings to the browser. It can be used to display the title of a web page dynamically, depending on the context or user input. In this article, we will show you how to use PHP echo to display the title of a web page in different scenarios.

Using PHP echo with a static title

If you have a static title for your web page, you can use PHP echo to display it inside the <title> tag in the head section of your HTML document. For example:

<html>
<head>
<title><?php echo "Welcome to my website"; ?></title>
</head>
<body>
...
</body>
</html>

This will output “Welcome to my website” as the title of your web page in the browser tab or window.

Using PHP echo with a variable title

If you have a variable title for your web page, you can use PHP echo to display it inside the <title> tag as well. You can assign a value to the variable from different sources, such as a database query, a user input, or a conditional statement. For example:

<?php
// Assign a value to the $title variable from a database query
$title = $row["title"];
?>
<html>
<head>
<title><?php echo $title; ?></title>
</head>
<body>
...
</body>
</html>

This will output the value of the $title variable as the title of your web page, which can be different depending on the database query result.

Using PHP echo with a function call

If you have a function that returns the title of your web page, you can use PHP echo to display it inside the <title> tag as well. You can define your own function or use a built-in function from a framework or library. For example:

<?php
// Define a function that returns the title of the web page
function get_title() {
// Some logic to generate the title
return $title;
}
?>
<html>
<head>
<title><?php echo get_title(); ?></title>
</head>
<body>
...
</body>
</html>

This will output the return value of the get_title() function as the title of your web page, which can be different depending on the logic inside the function.

Using PHP echo with HTML tags

PHP echo can also output HTML tags along with the strings, which can be useful for formatting or styling the output. You can use single or double quotes to enclose the HTML tags, but make sure to escape any quotes inside the tags with a backslash (\). For example:

<?php
// Output a paragraph with bold and italic text
echo "<p>This is a <b>bold</b> and <i>italic</i> text.</p>";
// Output a list with bullet points
echo "<ul>
<li>First item</li>
<li>Second item</li>
<li>Third item</li>
</ul>";
?>

This will output the following HTML elements in the browser:

This is a bold and italic text.

  • First item
  • Second item
  • Third item
