This is an example without escape slash: pink
This is an example using escape slash: $color
When using escape slash, you can escape a character by puting a backslash in front of it. For example, when a backlash is inserted in front of the variable color, then PHP is being told to ignore it and not run it as PHP so it is displayed as is without the variable being interpreted. You can also use the escape slash when trying to present a question mark.
