/* CAVEATS
1. Distinction between literal and interpreted values.
Using the $ to define a variable name signals that something should be interpreted.
What if we wanted to use a $ literally?
Example output: The name of the variable is $cost.
In the example below, we would see "The name of the variable is $2." because PHP
interprets $cost as a variable and not a literal.
To literally print $cost we need to "escape" the dollar sign.
print "The name of the variable is \$cost.
";
*/
$cost = "$2";
print "The name of the variable is $cost.
";
print "The name of the variable is \$cost.
";
/*
Here are some commonly used characters that you might need to escape.
\" double quote
\' single quote
\\ backslash
\$ dollar sign
*/
print "Here is an example in which I need to be \"careful\" with the use of double quotes.
";
