In PHP, the dollar symbol ($) is used as a prefix to signify variables. This convention helps PHP distinguish between variable names and other types of identifiers in the script. When PHP encounters a dollar sign followed by a string of characters, it recognizes it as a variable and interprets it accordingly. This naming convention aids in the parsing and execution of PHP scripts by indicating that the following identifier is a variable and should be evaluated or manipulated as such.

The use of the dollar symbol aligns with PHP's loosely typed nature, allowing variables to dynamically change their data type as needed. This flexibility is a characteristic of many scripting languages, and the dollar sign serves as a visual cue to both developers and the PHP interpreter that a variable is in use. While some other programming languages use different syntax or keywords for variable declaration, PHP's choice of the dollar symbol is a distinctive feature of its syntax and contributes to the language's recognizable and approachable style.
