    How do you declare a variable in PHP

    In PHP, you declare a variable by prefixing the variable name with a dollar sign ($) followed by the name you want to give to your variable. Variable names can consist of letters, numbers, and underscores, but they cannot start with a number.

    Here is an example of how to declare a variable in PHP:

    <?php $myVariable = "Hello, World!"; echo $myVariable; // Outputs: Hello, World! ?>
