$my_var = "cat";
echo "There is one $my_var on the mat";
/* If there were three cats, then you can type: */
echo "There are three {$my_var}s on the mat ";
/* The curly braces help to avoid confusion between the variable name and the letter s, so PHP does not consider the variable name as my_vars */In PHP, variables can be parsed within strings specified with double quotes (").
This means that within the string, the computer will replace an occurence of a variable with that variable’s value.
When additional valid identifier characters (ie. characters that could be included in a variable name) are intended to appear adjacent to the variable’s value, the variable name can be wrapped in curly braces {}, thus avoiding confusion as to the variable’s name.
