How can PHP developers efficiently concatenate and format strings from separate variables?

When concatenating and formatting strings from separate variables in PHP, developers can use the concatenation operator (.) to combine the variables and use sprintf() function to format the resulting string. This allows for efficient string manipulation and formatting without the need for excessive concatenation. 

// Concatenating and formatting strings from separate variables
$first_name = "John";
$last_name = "Doe";
$age = 30;

// Using concatenation operator and sprintf function
$formatted_string = $first_name . " " . $last_name . " is " . $age . " years old.";
echo sprintf("Formatted string: %s", $formatted_string);
