Variables are an important part of the programming languages. Variables are used to store information for basic types like name, age, label, address, count, etc. Variables are named accordingly related to the information or data we want to save. Variable Types As there are different data types we generally use...
All programming languages provide conditional statements in order to change the flow of the programs according to given conditions. If statement is most popular conditional statement provided very similar most of the programming languages. If statements provide single or most flow path according to given conditions like count, size, text,...
Arrays are an important part of the Programming languages. Arrays are used to store multiple values in a single data structure. An array generally stores a collection of items at the contiguous memory location. Arrays can be also called as List, Collection, etc. in programming languages like Python, C#, Java....
static keyword is used to store some data, variables, methods, blocks and nested class in memory permanently during the execution of the applications. static can be useful if we want to access the given programming language structures or provide access from other parts of the application. Use Cases static keyword...
Loops are a very important part of the programming languages. Loops are used to iterate over given collection, array, list, etc. There are mainly two types of loops named for loop and while loop. There are other types of loops but they can specially design for the specific programming languages....
A function is a basic element of the programming languages. The function is derived from mathematics where complex operations are summed and aggregated together for multiple use cases. In programming, languages function provides abstractions, simplicity, elegance for code which can be used multiple times with a simple call. Syntax Of...
Hash algorithms are the heart of the cryptography and security. SHA-256 is a Secure Hash Algorithm which will generate an output hash value in 256 bit. SHA-256 is designed by the National Security Agency (NSA). SHA-256 is one of the cryptographic hash functions. SHA-256 is also named one-way function where...
String is a very popular data type which can be used in different programming languages like JavaScript, Java, Python, C#, PHP, C, C++, PowerShell. String is mainly used to store characters like a text. Alternative data types are an integer, floating point, etc where they are mainly used for mathematical...
PHP programming language provides file() and readfile() functions in order to read a file. In this tutorial, we will learn how to use file() and readfile() functions in order to read text or similar ASCII files like PHP files. file() Function and Syntax file() function has a very basic syntax...
When dealing with the text files such as log files, user list, server list etc we can use regex for formally structured files. Space, white-space, and tab are popular separating elements used in regex or CSV files. In this tutorial, we will examine how to use regex with space, whitespace, tab...
