Are there any best practices for efficiently combining variables in PHP?

When combining variables in PHP, it is best practice to use string concatenation with the dot (.) operator for efficiency. This method avoids unnecessary memory usage and processing time compared to using complex interpolation or concatenation methods. By following this practice, you can ensure that your code runs smoothly and efficiently. 

// Example of efficiently combining variables in PHP
$variable1 = "Hello";
$variable2 = "World";

$combined = $variable1 . " " . $variable2;
echo $combined;
