A string is a sequence of letters, numbers, special characters and arithmetic values or combination of all. The simplest way to create a string is to enclose the string literal (i.e. string characters) in single quotation marks (‘), like this:<\/p>\n\n\n\n
Example:<\/strong> $my_string = ‘Hello World’;<\/p>\n\n\n\n You can also use double quotation marks (“). However, single and double quotation marks work in different ways. Strings enclosed in single-quotes are treated almost literally, whereas the strings delimited by the double quotes replaces variables with the string representations of their values as well as specially interpreting certain escape sequences.<\/p>\n\n\n\n The escape-sequence replacements are:<\/p>\n\n\n\n Here’s an example to clarify the differences between single and double quoted strings:<\/strong><\/p>\n\n\n\n Example: <\/p>\n\n\n\n\\n<\/code> is replaced by the newline character<\/li>\\r<\/code> is replaced by the carriage-return character<\/li>\\t<\/code> is replaced by the tab character<\/li>\\$<\/code> is replaced by the dollar sign itself ($<\/code>)<\/li>\\\"<\/code> is replaced by a single double-quote (\"<\/code>)<\/li>\\\\<\/code> is replaced by a single backslash (\\<\/code>)<\/li><\/ul>\n\n\n\n
