use single quotes: double quotes would confuse php with variable names.
it thinks that $General is a variable and replace it by it's empty content.
single quotes prevent php from evaluating the string:

$test_string = '1.2$General/'; 

single quotes on regex too (same reason). the backslash in this case
(\$) refers to perl regular expression syntax but does not take care of php !

$new_string = preg_replace('/\$/', "%", $test_string);
