fopen - PHP adding $ signs into strings without it being a variable? -

-

this question has answer here:

i'm making setup page people can write database login etc , create config.php file on webserver info can't write

$file = fopen("config.php", "w"); fwrite($file, "$dbname = $dbname");

i tried

$file = fopen("config.php", "w"); fwrite($file, "$" . "dbname = $dbname");

but doesn't work either.

any way store php variable in file write using php?

as php document says

if string enclosed in double-quotes ("), php interpret following escape sequences special characters: \$ dollar sign

http://php.net/manual/en/language.types.string.php

so if want use $ in double-quotes strings use \$ instead of $.

or use single quotes
