Built With

This section should list any major frameworks that you built your project using.

• PHP
• XAMPP

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

It is important that before starting you have an environment capable of running PHP in a version higher than 7.2. As we are going to use XAMPP we will be running 8 version which is the newest one. Here you can see the PHP releases:

https://www.php.net/downloads

Installing

To intalling and use this project you will need:

1. Install XAMPP

   https://www.apachefriends.org/download.html

2. Press start in order to turn on the services.

3. Go to XAMPP application and press the tab Volumes and press mount button once it is mounted you can press the button explore to open the XAMPP directory.

4. Clone the repo inside of htdocs for our project.

   git clone https://github.com/fab-rvn/PHP-Basics.git

php-basics's Issues

Conditionals

• Create a simple condition that evaluates whether the current day is Monday. Only in the case that the condition is met, it shows a message of “We are on Monday”.
• Create a simple condition that evaluates whether the current month is October. If the condition is met, it shows a message of the type "We are in October". Otherwise, if this condition is not met, show the current month in words as it come from DateTime.
• Create a double condition that evaluates:
  If the current minute is less than 10. Displays a message of type "the current minute is less than 10", if the current minute is greater than 15, displays a message of the type "the current minute is more than 15". If you do not meet any of the two conditions above: Displays a message of the type "does not meet any conditions”
• Create a switch type control structure to display a different message depending on the current day of the week. You can write any type of message

Add readme

Dates

• Use date class to show year-month-day
• Get the current date in any format
• Get the current day
• Get the current month in numerical format (1-12)
• Get the current minute with leading zeros (00 - 59)

Operators

• Use the var_dump PHP function which is to debug variables
• Use arithmetic operators: +, -, *, /, and%
• Use a comparison operators: ==,! =, <,>, <=,> =
• Use a logical operators: &&, ||, !, xor

Functions

• Generate a function that given two numbers returns the sum of both
• Generates a function that given two numbers returns the multiplication of both
• Generates a function that given two numbers returns the division of both
• Generates a function that, given two numbers and an operation (add, multiply or divide), returns the result of that operation.
• Depending on the type of operation received by parameter, the function will execute the function responsible for performing the operation, since you have previously implemented the function for each operation separately.

Types

• Define a new variable and assign a value to each of the following types:
  • Boolean
  • Integer
  • Float
  • String
  • Array
  • Object
  • NULL

Maths

• Define a variable whose value is the result of the function that returns an absolute value.
• Define a variable whose value is the result of the function that returns a rounded value to the next highest integer.
• Define a variable whose value is the result of the function that returns the highest value of a series of values ​​that are received by parameter.
• Define a variable whose value is the result of the function that returns the lowest value of a series of values ​​that are received by parameter.
• Define a variable whose value is the result of the function that returns a random number

Arrays

• Define a simple array composed of text strings
• Define a simple array consisting of whole numbers and decimal numbers
• Define a multidimensional array
• Execute the function that allows to obtain the length of an array
• Execute the function that allows to obtain the combination of two arrays
• Execute the function that once is given an array return the last element of it
• Execute the function that once is given an array add a new element to the array in question

Iterators

• Make use of "for"
• Make use of "foreach"
• Make use of "while"
• Make use of "do while"

Print

• Make use of "echo"
• Make use of "print"
• Makes use of "print_r"

Info

• Create a folder called src and inside create a file called index.php
• Call the phpinfo function and verify the result

Strings

• Print a text string
• Print a text string that interpret variables
• Concatenate a previously declared variable in a text string
• Execute the function that allows you to replace text in a string (case sensitive)
• Execute the function that allows you to replace text in a string (without taking into account upper / lower case)
• Execute the function that allows you to write a text N times
• Execute the function that allows to obtain the length of a text string
• Executes the function that allows to obtain the position of the first occurrence of a text within a text string
• Execute the function that allows a text string to be capitalized
• Execute the function that allows you to transform a text string to lowercase
• Execute the function that allows to obtain a text substring from the position
