Step 2: Database Config

<?php
//db details
$dbHost = 'localhost';
$dbUsername = 'root';
$dbPassword = '';
$dbName = 'country';

//Connect and select the database
$db = new mysqli($dbHost, $dbUsername, $dbPassword, $dbName);

if ($db->connect_error) {
    die("Connection failed: " . $db->connect_error);
}
?>

Step 2: Create the index page

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>

</head>
<body>
    <div class="select-boxes">
    <?php
    //Include database configuration file
    include('dbConfig.php');
    
    //Get all country data
    $query = $db->query("SELECT * FROM countries WHERE status = 1 ORDER BY country_name ASC");
    
    //Count total number of rows
    $rowCount = $query->num_rows;
    ?>
    <select name="country" id="country">
        <option value="">Select Country</option>
        <?php
        if($rowCount > 0){
            while($row = $query->fetch_assoc()){ 
                echo '<option value="'.$row['country_id'].'">'.$row['country_name'].'</option>';
            }
        }else{
            echo '<option value="">Country not available</option>';
        }
        ?>
    </select>
    
    <select name="state" id="state">
        <option value="">Select country first</option>
    </select>
    
    <select name="city" id="city">
        <option value="">Select state first</option>
    </select>
    </div>
</body>
</html>

Step 3: create jquery with ajax function to pass country id into next page and select state and cities form the database table

<script src="jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
    $('#country').on('change',function(){
        var countryID = $(this).val();
        if(countryID){
            $.ajax({
                type:'POST',
                url:'ajaxData.php',
                data:'country_id='+countryID,
                success:function(html){
                    $('#state').html(html);
                    $('#city').html('<option value="">Select state first</option>'); 
                }
            }); 
        }else{
            $('#state').html('<option value="">Select country first</option>');
            $('#city').html('<option value="">Select state first</option>'); 
        }
    });
    
    $('#state').on('change',function(){
        var stateID = $(this).val();
        if(stateID){
            $.ajax({
                type:'POST',
                url:'ajaxData.php',
                data:'state_id='+stateID,
                success:function(html){
                    $('#city').html(html);
                }
            }); 
        }else{
            $('#city').html('<option value="">Select state first</option>'); 
        }
    });
});
</script>

Ajax page for select database of cities and states

<?php
//Include database configuration file
include('dbConfig.php');

if(isset($_POST["country_id"]) && !empty($_POST["country_id"])){
    //Get all state data
    $query = $db->query("SELECT * FROM states WHERE country_id = ".$_POST['country_id']." AND status = 1 ORDER BY state_name ASC");
    
    //Count total number of rows
    $rowCount = $query->num_rows;
    
    //Display states list
    if($rowCount > 0){
        echo '<option value="">Select state</option>';
        while($row = $query->fetch_assoc()){ 
            echo '<option value="'.$row['state_id'].'">'.$row['state_name'].'</option>';
        }
    }else{
        echo '<option value="">State not available</option>';
    }
}

if(isset($_POST["state_id"]) && !empty($_POST["state_id"])){
    //Get all city data
    $query = $db->query("SELECT * FROM cities WHERE state_id = ".$_POST['state_id']." AND status = 1 ORDER BY city_name ASC");
    
    //Count total number of rows
    $rowCount = $query->num_rows;
    
    //Display cities list
    if($rowCount > 0){
        echo '<option value="">Select city</option>';
        while($row = $query->fetch_assoc()){ 
            echo '<option value="'.$row['city_id'].'">'.$row['city_name'].'</option>';
        }
    }else{

First create html file

<html lang="en">
<head>
  <meta charset="utf-8">
  <title>Simple JavaScript Calculator</title>

</head>
 
<body>
<h2>Simple JavaScript Calculator</h2>
 
<form name="calcForm">
<table>
<tr>
  <td colspan="4"><input type="text" name="display"
                         style="text-align:right"></td>
</tr>
<tr>
  <td><input type="button" name="btn1" value="1"
             onclick="calcForm.display.value += '1'"></td>
  <td><input type="button" name="btn2" value="2"
             onclick="calcForm.display.value += '2'"></td>
  <td><input type="button" name="btn3" value="3"
             onclick="calcForm.display.value += '3'"></td>
  <td><input type="button" name="btnAdd" value="+"
             onclick="calcForm.display.value += ' + '"></td>
</tr>
<tr>
  <td><input type="button" name="btn4" value="4"
             onclick="calcForm.display.value += '4'"></td>
  <td><input type="button" name="btn5" value="5"
             onclick="calcForm.display.value += '5'"></td>
  <td><input type="button" name="btn6" value="6"
             onclick="calcForm.display.value += '6'"></td>
  <td><input type="button" name="btnSub" value="-"
             onclick="calcForm.display.value += ' - '"></td>
</tr>
<tr>
  <td><input type="button" name="btn7" value="7"
             onclick="calcForm.display.value += '7'"></td>
  <td><input type="button" name="btn8" value="8"
             onclick="calcForm.display.value += '8'"></td>
  <td><input type="button" name="btn9" value="9"
             onclick="calcForm.display.value += '9'"></td>
  <td><input type="button" name="btnMul" value="x"
             onclick="calcForm.display.value += ' * '"></td>
</tr>
<tr>
  <td><input type="button" name="btnClear"
             value="C" onclick="calcForm.display.value = ''"></td>
  <td><input type="button" name="btn0" value="0"
             onclick="calcForm.display.value += '0'"></td>
  <td><input type="button" name="btnEqual" value="="
             onclick="calcForm.display.value = eval(calcForm.display.value)"></td>
  <td><input type="button" name="btnDiv" value="/"
             onclick="calcForm.display.value += ' / '"></td>
</tr>
</table>
</form>
 
</body>
</html>

Step 2: Add Css file for the page

input {
       font-family: consola, monospace;
       color: blue;
     }
     td {
       margin-left: auto;
       margin-right: auto;
       text-align: center;
     }
     table {
       border: thick solid;
     }

Step 3: Add javascript for the calci function.

window.onload = initClock;
 
function initClock() {
  var now = new Date();
  var hr  = now.getHours();
  var min = now.getMinutes();
  var sec = now.getSeconds();
  if (min < 10) min = "0" + min;  // insert a leading zero
  if (sec < 10) sec = "0" + sec;
  document.getElementById('clockDisplay').innerHTML
        = "Time is " + hr + ":" + min + ":" + sec;
  setTimeout('initClock()', 500);

<?php
$search =array('a'=>'php','b'=>'css','c'=>'html,'d'=>'dssd','e'=>'eeee',f=>'fdfd','g'=>'dsfsd',....);
echo array_search('css',$search);
?>

In the Given example, we have to find whether “CSS” Find or not in the array. It prints the key of the value.

Output

b // output

Explaination

array_search is used to search the array value(‘css’) and returns the value’s key(‘b’);

2. In_array()

In_array is simillar to the array_search

In_array Functions is used to find the value in the array list

syntax: In_array();

you can search anything value or key using IN_ARRAY();

for example

have to find “Developerdesks” in the given array

<?php

$var = array(‘raj’,’sekar’,’developer’,’desks’,'php','html','css','developerdesks','designer');

if(in_array('developerdesks', $var, ))

How can we print array with in array using for-each loop – Three dimensional array

A multidimensional array is an array containing one or more arrays.

Three-Dimensional array

For three dimensional array u have to use two for loop condition
find 0 indexed array value and then 0 indexed array value

<?php

$developedesks = array(
"Skills" => array
(
"php" => 80,
"css" => 85,
"html" => 80
),
"design" => array
(
"photoshop" => 70,
"flash" => 75,
"indesign" => 72
),
"framework" => array
(
"wordpress" => 85,
"drupal" => 75,
"joomla" => 70
)
);

$count = count($developedesks);
echo "$count<br/>";
foreach($developedesks  as $develop => $desks)
{

foreach($desks as $key =>$value)
{
echo "$develop &nbsp; $key &nbsp; $value<br/>";
}

}

?>

Explain

First foreach consider skill as $develop and php =>80 as $desks

Second For each consider $key as php and $ value as 80

so the $develop –> indexed as skill, $key–> indexed as php and $value indexed as 80

simple foreach concept worked

Output

Skills  php  80
Skills  css    85
Skills  html   80
design  photoshop 70
design  flash    75
design  indesign   72
framework wordpress 85
framework drupal   75
framework joomla   70

<?php

$develop= array(
array("developer",php,html),
array("desks",php5,html5),
array("raja",css,ajax),
array("sekar",jquery,drupal)
);

$count= count($develop);
echo "$count";

 for ($row = 0; $row < $carss; $row++) {
echo "<p><b>Level $row</b></p>";
echo "<ul>"; 
for ($col = 0; $col < 3; $col++) {
echo "<li>".$cars[$row][$col]."</li>";
}
echo "</ul>";
}

?>

Output

Indexed Level 0
developer
php
html

Indexed Level 1
desks
php5
html5

Indexed Level 2
raja
css
ajax

Indexed Level 3
sekar
jquery
drupal

Explanation:

First For loop consider all array values inside the array –> array(“developer”,php,html) as 0 indexed

Second For loop consider inside values –> Developer as 0 indexed

For two dimensional array u have to use two for loop condition

find 0 indexed array value and then 0 indexed array value

simple example

<?php

echo $develop[0][0].": langauge 1: ".$develop[0][1].", language 2: ".$develop[0][2].".";
echo $develop[1][0].": langauge 1: ".$develop[1][1].", langauge 2: ".$develop[1][2].".";
echo $develop[2][0].": langauge 1: ".$develop[2][1].", langauge 2: ".$develop[2][2].".";
echo $develop[3][0].": langauge 1: ".$develop[3][1].", langauge 2: ".$develop[3][2].".";

If you know the total number of array values means you can do like this,

For unknown and unlimited array values are present then go to Forloop

Example

< ?php
$var1 = array('one','122','122','122','dfd','dfgdf','dfgdfg','dfgdfg','dfgdfgf','dfgdfg','dfgdfgdf','gfdgdfg','dfgdfgdf','fdg','dfgdf','last');

$total = count($var1); // Use Count(); functions

for($i=0; $i< $total; $i++)
{
echo "$var1[$i]
";
}
