PHP Heredoc

In PHP, a Heredoc is a way to define strings that span multiple lines and can contain variables, making it an alternative to double-quoted strings (") for creating multiline strings. Heredoc syntax is useful when you need to include a large block of text or HTML within your PHP code. Here's the syntax for using Heredoc in PHP:

    $variable = <<<EOT
    This is a Heredoc string.
    It can span multiple lines.
    Variables like \$variable are interpolated: $variable.
    EOT;
    

Here's a breakdown of the Heredoc syntax:

$variable: This is the name of the variable that will store the Heredoc string.

<<<EOT: The opening tag for the Heredoc. EOT is a delimiter, but you can choose any custom identifier as long as it doesn't conflict with your actual text.

The text inside the Heredoc: You can include any text, line breaks, and variables within the Heredoc. Variables are interpolated (their values are inserted) inside the Heredoc as shown in the example.

EOT;: The closing tag for the Heredoc. It must be on a line by itself, and no spaces or characters should precede it except for a semicolon.

Here's an example of using Heredoc in PHP:

<?php
$name = "Alice";
$age = 30;

$message = <<<EOT
Hello, my name is $name.
I am $age years old.
EOT;

echo $message;
?>

Hello, my name is Alice.
I am 30 years old.
