Q.3. Write a PHP Script for the following: a) Declare and Display a multidimensional Array. b) Search and display a specific element from a Multidimensional array.

    
      <?php

  //input rows & columns

  $row=readline();

  

  echo"Enter number of columns";

  $columns= readline();

//define array

  $multarr= array();

 //Taking multidimentional array from user

  for($i=0; $i<$row;$i++)

  {

    for($j=0;$j<$columns;$j++)

    {

      //input value

       echo"Enter value of row: $i column: $j ";

       $val=intval(readline());

       

       //add the inputted value inside the array as specific row and column using "i","j"

       $multarr[$i][$j]=$val; 

    }

  }

  

  //displaying the array

  echo"Elements of the Multidimentional array are:\n";

  foreach($multarr as $rows)

  {

    foreach($rows as $values)

    {

      echo"$values ";

    }

    echo"\n";

  }

  

  //enter element for search

  $search=intval(readline());

  //declare a flag

  $flag=0;

  

  //Searching the values from array

  

  for($i=0; $i<$row;$i++)

  {

    for($j=0;$j<$columns;$j++)
