A variable is identified by the $ sign, which is followed by the variable's name.
The name of a variable must begin with a letter or an underscore.
A number cannot be the first character in a variable name.
Only alpha-numeric characters and underscores (A-z, 0-9, and _) are allowed in variable names.
PHP has three different variable scopes, depending on the scopes: local, global, and static variable scope.
A variable's value is the result of its most recent assignment. Variables in PHP don't have inherent types, which means they don't know if they'll be used to store a number or a string of characters before they're used. Variables with default values are those that are utilised before they are assigned.
Variables are used to store values or data in a programme so that they can be utilised later. Character values, numeric values, memory addresses, and strings are all stored in variables, which are similar to containers.

It would have been better if you could have provided the resource/source_code files of the CRUD operations so that we could have cross verified our code with yours.
Excellent for Bigners.
