The logical OR operator in C and Java is the double vertical bar ().Example: if (s 0) do somethingThe operator applies a logical OR operator when it evaluates the expression.
Boolean algebra is a mathematical structure that deals with binary variables and logic operations. It is used to represent and manipulate logical expressions and truth values. Boolean algebra is especially important in computer science and digital logic design, where it is used for constructing circuits, Boolean functions, and making logical decisions.

There are several boolean operators in PHP. I'm not able to provide you with it's full list, but here are some of the most used ones: && - AND - OR ! - NOT
Although it is more logical and closer to science than maths, boolean algebra can be used with normal algebra on planes, and it uses variables.
Boolean is used primarily in computer science and mathematics to represent logical values, typically true and false. It forms the basis for Boolean algebra, which is essential in digital circuit design, programming, and search algorithms. Additionally, Boolean logic is used in search engines and databases to refine queries through operators like AND, OR, and NOT, enabling more precise information retrieval.
The boolean operator that omits information from the search parameters is the NOT operator. When used in a search query, it excludes specific terms, helping to refine results by filtering out unwanted content. For example, searching for "cats NOT dogs" will return results related to cats while excluding any mentions of dogs.
The logical or boolean data type is used to store true/false data. In some databases it can also be expressed as yes/no, 1/0, etc. For example you're either 21 or older or you're not 21 or older. In the US, you have to be 21 or older to drink alcohol legally. So you might store that kind of information about a person in a boolean/logical field named 'legal' and get that information by asking 'Are you 21 or older?'Logical data is generally represented as a diagram and described in business language.
A Boolean or logical data type can be used to store anything that can answer a "yes/no" question. In other words, anything that has two options. For example:Does the checkbox have a check mark?Is the person underage?Does a certain file exist on disk?etc.A Boolean or logical data type can be used to store anything that can answer a "yes/no" question.
