Don't put variables inside single quotes

echo $turl; // --> http://example.com
echo '$turl'; //--> $turl

To expand on Barand's response. If you are ONLY using the value of a variable, then don't put it in quotes at all - as he stated. However, there are times that you want to concatenate the value of a variable with other string elements. In those case you can put the variable in a double quoted string. PHP has several ways of dealing with quoted text and in some variables are interpreted. In others the variable is treated as a string. Of course, you don't have the include the variable in the string at all and just concatenate the variable to the other string elements using the period.
