What does "undefined variable" mean in Laravel 10 and PHP 8.2?

edit

"Undefined variable" refers to an error in coding where a variable is used without being previously defined. In Laravel 10 and PHP 8.2, this error message may appear if a variable is used in a script or function without being declared first. This could mean that the variable was misspelled, or that it was not initialized before it was used. To avoid this error, it's important to make sure all variables are properly declared and initialized before they are used.
