Special Characters – PHP

Special Characters

PHP special characters are characters that have a special meaning in PHP and are used for specific purposes. Here are some commonly used PHP special characters:

Dollar sign ($) – Used to declare and access variables in PHP.
Double quote (“) – Used to enclose strings that can contain variables or escape sequences.
Single quote (‘) – Used to enclose strings that are treated as literals and do not support variable interpolation or escape sequences.
Backslash () – Used as an escape character to represent special characters or escape sequences within strings.
Ampersand (&) – Used to concatenate strings or pass arguments by reference.
Question mark (?) – Used in the ternary operator to represent a conditional expression.
Exclamation mark (!) – Used to represent the logical NOT operator.
Forward slash (/) – Used as a path separator in file paths.

It’s important to properly handle and sanitize input containing special characters to prevent potential security vulnerabilities in your PHP code.
