This question already has an answer here:
I want to make a php variable a group of other variables so that I can put the new group of variables into a .txt file. Something like:
$txt = $_GET["html"]
$txt2 = $_GET["js"]
$txt3 = $_GET["php"]
$txt4 = $_GET["other"]
$text = $txt $txt2 $txt3 $txt4;
$filename = fopen("config.txt", "w");
fwrite($filename, $text);
fclose($filename);
I have searched on Google and Stack Overflow, but nothing seems to solve my problem.

If you just want to combine multiple string values into one string value then the term you're looking for is "concatenate", which in PHP is done with the . operator:
$text = $txt . $txt2 . $txt3 . $txt4;
