Example NOT using PHP escape slash: It's a beautiful day
The escape slash (\) in PHP is used to indicate that the character following it should be treated literally and not as part of the syntax. For example, in strings, it allows you to include special characters like single quotes without ending the string early. Without using the escape slash, placing a single quote inside a single-quoted string would cause a parsing error. Thus, escaping ensures special characters do not disrupt your code and allows those characters to appear as part of the string content.
