Hi  Recently i went to interview i was asked to add a mark and find the rank of it using php. 1) First i created a function called  rankChecker and passing  two parameter like collection of marks in array and mark that will be added and finding the rank of it. 2) Then i created dumpy variable $s ,$ab as array. 3)After that i added the mark in the array mark list and sorted into descending order and looped in for loop. 4) passing the value of first array into dumpy array $ab as key and passing the $i value  incremented by one as $i starts with zero. 5) And returning the current $ab array and passing $mark as key value in it. function rankChecker($arr,$mark){ $arr[] = $mark; rsort($arr); $ab = array(); //echo count($arr);    for($i=0;$i<count($arr);$i++){          $ab[$arr[$i]] = $i+1;       } return $ab[$mark]; } $arr=[39,37,34,56,67,23,37]; $mark=10; print_r(rankChecker($arr,$ mark));

1) first loop considering $i as row and $j as column ,where total number of row is 4 and column is 7. 2) second is print * as passing the condition as following. CODE: for($i=1;$i<=4;$i++){     for($j=1;$j<=7;$j++){             if($i==1 && $j==4)             {                 echo "*";             } else if(($j==3 || $j==5)&& $i==2 )             {                 echo "*";             }else if(($j==2||$j==6)&&$i==3)             {                 echo "*";             } else if(($j==1||$j==7)&&$i==4){                 echo "*";         ...

1) First step is to sort the array in desc. 2) create two variable  like $fh as first highest and $sh as second highest. 3) loop the array in foreach ,we will check the if condition to first val is greater then $fh variable ,where first iteration first highest value will be assigned to $fh value. 4) second  else if condition will be same ,but here variable will be $sh and another condition in is check duplicate value of highest in the array. $arr = [55,40,50,76,76,40,30,20,60,89]; rsort($arr); $fh=0; $sh=0; foreach($arr as $val){     if($val > $fh){         $fh = $val;     } elseif(($val>$sh) && ($val != $fh)){         $sh = $val;     }   } echo $sh;

Recently I was working on mobile project in which we were working on service code in php, To find the pair in certain number in list.  Example:  $total = 4; $pair_total = $total * ($total - 1) * 0.5; // 6 So here we are able to find the pair combination using this formula.And pls comment if there any tricks similar to this.

I was working around oops in php 7 ,in which I pass class name and variable to another class constructor function to access the function of it Like inheritance concept.Let me brief with example Example for passing class name and variable in constructor  : class A{    public function execute($user){    echo $user;   } } class B {   protected $a; //where we pass Class A  inside constructor   public function __construct(A $a){      $this->a = $a;   }  public function show(){     $user = 'pramodh';     $this->a->execute($user);    } } $b = new B(new A); $b->show(); Out Put : Pramodh Example for passing just variable  in constructor  : class A{    public function execute($user){    echo $user;   } } class B {   protected $a; //where we pass Class A  inside constru...

Hi Friends I was working on web application in which we have to disable browser back button,so search number solution in stackoverflow and found best suitable solution for it.I wanted to share that code ,so that developer can save time on searching. history.pushState(null, null, document.URL); window.addEventListener('popstate', function () { history.pushState(null, null, document.URL); });
