 Programmings Based On Array And String Functions To Merge The 2 Arrays, Then After Merge Convert Into String And Then Find Out The 1st And Last Word From The Reverse String

Q1. Take 2 arrays then margin the arrays. After margin convert into string then reverse the string and find out 1st and last word from the reverse string.

Ans: Coding =>

<?php

$arr1=["Dhoni","Rohit","Kohli","Rahul"];

$arr2=["Bumrah","Shami","Siraj","Chahal"];

$arrmer=array_merge($arr1,$arr2);

print_r($arrmer);

echo "<br>";

$str=implode(" ", $arrmer);

print_r($str);

echo "<br>";

$strrev=strrev($str);

print_r($strrev);

echo "<br>";

$arr=explode(" ", $strrev);

print_r($arr);

echo "<br>";

$firstword=array_shift($arr);

$lastword=array_pop($arr);

print_r($firstword);

echo "<br>";

print_r($lastword);

?>

Output Of The Coding =>

Explanation Of The Coding =>

Here my first output in the output page is of array merge where I have taken two arrays one is $arr1 and another is $arr2 and then I have merged this two arrays using array_merge() function.

                                        Then my second output is in string where I have convert the array merge i.e. $arrmer into string by using implode() function.

                                                           Then my third output is of reverse string after converting the array into string I have reversed the string by using strrev() function.

                                                                                       Then my fourth output is of array that is to find the first and last word from the string I need to first convert the string into array using explode() function, which I have done in my fourth step.

                    Then my fifth output is of first word where I have finded out the first word from the reverse string using by array_shift() function.

                                               Then my sixth output is of last word where I have finded out the last word from the reverse string by using array_pop() function.
