Strings are sequences of characters used to store and manipulate text. PHP provides a variety of functions for working with strings, making it easy to create, modify, and manipulate text content.



1. Creating Strings


Single Quoted Strings:

The simplest way to create a string. It does not interpret variables or special characters (except for \\ and \').

Example
Try it yourself

Double Quoted Strings:

More flexible. They parse variables and escape sequences like \n (newline).

Example
"; echo $newline."
"; echo $str; ?>
Try it yourself
