What are PHP variables and how are they declared?

Entry PHP
Quick Answer PHP variables start with $ sign followed by a letter or underscore. Dynamically typed - no type declaration needed (though type hints are supported in PHP 7+). $name = "Alice"; $age = 25; $price = 9.99; $active = true. Variable names are case-sensitive. PHP 8 added typed properties and union types. Variables don't need to be declared before use.

Answer

PHP variables start with $ and are dynamically typed, meaning type is assigned at runtime.
