Are there any specific best practices for concatenating variable names in PHP?

When concatenating variable names in PHP, it is best practice to use curly braces to clearly separate the variable name from the rest of the string. This helps improve readability and avoid any potential parsing issues. By enclosing the variable name within curly braces, you ensure that PHP interprets it correctly within the concatenated string. 

// Concatenating variable names using curly braces
$first_name = 'John';
$last_name = 'Doe';

$full_name = "{$first_name} {$last_name}";

echo $full_name; // Output: John Doe
