How can you ensure that variables are displayed as values and not as text when writing to a file in PHP?

When writing variables to a file in PHP, you need to ensure that the variables are displayed as values and not as text. To achieve this, you can use double quotes around the variables when writing to the file. This will allow PHP to interpret the variables and display their values instead of treating them as plain text. 

// Example code snippet
$variable1 = "Hello";
$variable2 = "World";

$file = fopen("output.txt", "w");
fwrite($file, "Variable 1: $variable1\n");
fwrite($file, "Variable 2: $variable2\n");
fclose($file);
