  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 "...
