What is the correct syntax for passing multiple variables in a PHP link?

When passing multiple variables in a PHP link, you can use the '&' symbol to separate each variable-value pair. This allows you to pass multiple parameters in the URL query string. To do this, you need to concatenate the variables and their values with the '&' symbol.

// Example of passing multiple variables in a PHP link
$variable1 = 'value1';
$variable2 = 'value2';

echo '<a href="page.php?variable1=' . $variable1 . '&variable2=' . $variable2 . '">Link</a>';
