Write Smart code in PHP arrays using in built functions.

We have a requirement to fetch data from database and display user names and their salaries.

Output required:

Morgan's salary: 6000, Jermy's salary: 5500, Phil's salary: 5500, Anthony's salary: 5500, John's salary: 5500, Norman's salary: 5500

There are 2 ways of doing this that generate the same result.

<?php

$databseArray = [];

$databseArray[] = [1, 'Morgan', 6000];

$databseArray[] = [2, 'Jermy', 5500];

$databseArray[] = [3, 'Phil', 5500];

$databseArray[] = [4, 'Anthony', 5500];

$databseArray[] = [5, 'John', 5500];

$databseArray[] = [6, 'Norman', 5500];

echo 'Approach 1';

echo '<br/>';

if (! empty($databseArray)) {

 $str = '';

 $cntr = 0;

 $len = count($databseArray);

 foreach ($databseArray as $databseRow) {

  $str .= ' '.$databseRow[1] ."'s". ' salary: '.$databseRow[2];

  if ($cntr < ($len-1))

  $str .= ', ';

  ++$cntr;

 }

}

echo $str;

echo '<br/>--------------------------------------------------------------<br/>';

echo 'Approach 2';

echo '<br/>';

$outputArr = [];

if (! empty($databseArray)) {

 foreach ($databseArray as $databseRow) {

  $outputArr[] = ' '.$databseRow[1] ."'s". ' salary: '.$databseRow[2];

 }

}

echo implode(', ', $outputArr);

Design Pattern in PHP

<?php

class Booklibrary {

 private $bookName = '';

 private $bookAuthor = '';

 const BR = '<br/>';

 public function __construct($name = '', $author = '') {

  $this->bookName = $name;

  $this->bookAuthor = $author;

 }

 public function getNameAndAuthor() {

  return $this->bookName . ' - ' . $this->bookAuthor . self::BR;

 }

}

class BooklibraryFactory {

 public static function create($name, $author) {

  return new Booklibrary($name, $author);

 }

}

$bookOne = BooklibraryFactory::create('Shiv Khera', 'You can win');

$bookTwo = BooklibraryFactory::create('Norman Vincent Peale', 'The Power Of Positive Thinking.');

echo $bookOne->getNameAndAuthor();

echo $bookTwo->getNameAndAuthor();

ReactJS useState() method explained

 The ReactJS useState() method is used to save and set state variables in the React Components.

For this to use, we need to import useState() from React.

The useState() method returns an array.

It has two parameters:

1) state variable

2) function to change state variable.

For example:

const [count, setCount] = useState(0);

Here we are destructing the useState() array with two variables.

the count is variable and setCount is a method.

// Import useState from React

import {useState} from 'react';

function App() {

 const [count, setCount] = useState(0);

}

We can set the count using setCount() method.

My First Component to Toggle Color and Color Name

 import { Fragment, useState, useReducer } from 'react';

function reducer(state, action) {

  console.log(state);

  console.log(action);

  switch (action.type) {

    case 'Green':

      return action.type;

      break;

    case 'Red':

      return action.type;

      break;

    case 'Yellow':

      return action.type;

      break;

    case 'Pink':

      return action.type;

      break;

  }

  return state;

}

function Toggle() {

  //const [state, setState] = useState('pink');

  const [state, dispatch] = useReducer(reducer, 'Pink');

  return (

    <Fragment>

      The color is{' '}

      <span style={{ backgroundColor: state, padding: '5px' }}> {state} </span>

      <button

        onClick={() => {

          dispatch({ type: 'Green' });

        }}

      >

        Green

      </button>

      <button

        onClick={() => {

          dispatch({ type: 'Red' });

        }}

      >

        Red

      </button>

      <button

        onClick={() => {

          dispatch({ type: 'Yellow' });

        }}

      >

        Yellow

      </button>

      <button

        onClick={() => {

          dispatch({ type: 'Pink' });

        }}

      >

        Pink

      </button>

    </Fragment>

  );

}

export default Toggle;

Drupal 8 programmatically get list of themes installed
