 Write a PHP script to merge two arrays and sort them as numbers, in descending order

Source Code:

Week-3/Week3.php


<html>

<head>

    <title>Merge and sort two arrays in PHP</title>

</head>

<body>

<?php

    // creating arrays

    $f_array=array(6,9,0,8,1,2);

    $s_array=array(4,7,5,3);

    // to display array elements

    echo "Elements of First Array are : <br> ";

    for($i = 0;$i < count($f_array);$i++) {

Web Programming Lab Manual

1) Write a PHP script to print prime numbers between 1-50 View Solution

2) PHP script to a) Find the length of a string. b) Count no of words in a string. c) Reverse a string. d) Search for a specific string. View Solution

3) Write a PHP script to merge two arrays and sort them as numbers, in descending order View Solution
