A String refers a series of characters such as 'Hello, Programmers!'. It is an important part of the programming languages. A string can be letters, numbers, spaces, and special characters. PHP helps us to manipulate the string with a rich set of built-in functions. Those functions make the programmers life easy. The common using of string are concatenation, searching, replacement, splitting, and formatting.
A string can be single-quoted or double-quoted. In most programming languages, a single-quoted string is treated as a character literal, whereas a double-quoted string is treated as a string literal. Additionally, in some programming languages, double quotes are used to enclose string interpolation expressions, whereas single quotes are not.
