Examples of Using Single Quotes Vs Double Quotes

Below is an example of using double quotes...
My dress cost 80 dollars (double)

Below is an example of just using single quotes...
My dress cost $clothesprice! (single)

What's the difference between single and double quotes in PHP?

- Single quotes: PHP treats everything inside single quotes exactly as it is.
It doesn't change variables or special characters.

- Double quotes: PHP does change variables and special characters inside double quotes.
So, if you put a variable in double quotes, it will show the variable's value.

In this example...
- With single quotes, `$clothesprice` will stay as `$clothesprice`.
- With double quotes, `$clothesprice` will show its value, like 80.00.
Pretty cool, right?
