Remember, single-quotes ( `’` ) make literal strings – every character you type ( except “, but let’s not get into that right now) will be exactly as you see it.
With double-quotes ( `”` ) , PHP will interpret variables and escape characters in the string. So,
$var = ‘world’;
echo ‘Hello, $var’; # prints “Hello, $var”
echo “Hello, $var”; #prints “Hello, world”
