Array in PHP

1) An array is a special variable, which can hold more than one value at a time.

2) An array is used to store multiple values, in a single variable.

Types of Arrays in PHP

There are three types of arrays . These are:

Indexed array :- An array with a numeric key.
Associative array :- Arrays with named keys .
Multidimensional array :- An array containing one or more arrays .

1) Indexed Arrays in PHP

PHP index starts from 0. You can store number, string and object in PHP array.

Two examples shows in creating way an indexed array.

Example 1 :-

 <!DOCTYPE html>
<html lang="en">
<head>
    <title>PHP Indexed Arrays</title>
</head>
<body>

<?php
$colors = array("PHP", "Java", ".Net");

// Printing array structure
print_r($colors);
?>

</body>
</html>                   

Output

 Array ( [0] => PHP [1] => Java [2] => .Net )

Example 2 :-

 <!DOCTYPE html>
<html lang="en">
<head>
    <title>PHP Indexed Arrays</title>
</head>
<body>

<?php  
$season[0]="PHP";  
$season[1]="HTML";  
$season[2]="CSS";  
$season[3]="JS";  
echo "Season are: $season[0], $season[1], $season[2] and $season[3]";  
?>  

</body>
</html>                                	

Output

 Season are: PHP, HTML, CSS and JS

2) Associative Arrays in PHP

Associative Arrays using this type of symbol =>

Example 1 :-

 <!DOCTYPE html>
<html lang="en">
<head>
    <title>PHP Associative Array</title>
</head>
<body>

<?php    
$salary=array("Peter"=>"350000","John"=>"450000","Kartik"=>"200000");    
echo "Peter salary: ".$salary["Peter"]."<br/>";  
echo "John salary: ".$salary["John"]."<br/>";  
echo "Kartik salary: ".$salary["Kartik"]."<br/>";  
?>    

</body>
</html>                     

Output

 Peter salary: 350000
John salary: 450000
Kartik salary: 200000

Example 2:-

 <!DOCTYPE html>
<html lang="en">
<head>
    <title>PHP Associative Array</title>
</head>
<body>

<?php    
$salary["Peter"]="350000";    
$salary["John"]="450000";    
$salary["Kartik"]="200000";    
echo "Peter salary: ".$salary["Peter"]."<br/>";  
echo "John salary: ".$salary["John"]."<br/>";  
echo "Kartik salary: ".$salary["Kartik"]."<br/>";  
?>    
</body>
</html>      

Output

 Peter salary: 350000
John salary: 450000
Kartik salary: 200000

3) Multidimensional Arrays in PHP

A multidimensional array store date in tabular form and which is represented in matrix form row * column.

Example 1 :-

 <!DOCTYPE html>
<html>
<body>

<?php
$cars = array
  (
  array("Volvo",22,18),
  array("BMW",15,13),
  array("Saab",5,2),
  array("Land Rover",17,15)
  );
  
echo $cars[0][0].": In stock: ".$cars[0][1].", sold: ".$cars[0][2].".<br>";
echo $cars[1][0].": In stock: ".$cars[1][1].", sold: ".$cars[1][2].".<br>";
echo $cars[2][0].": In stock: ".$cars[2][1].", sold: ".$cars[2][2].".<br>";
echo $cars[3][0].": In stock: ".$cars[3][1].", sold: ".$cars[3][2].".<br>";
?>

</body>
</html>

Output

 Volvo: In stock: 22, sold: 18.
BMW: In stock: 15, sold: 13.
Saab: In stock: 5, sold: 2.
Land Rover: In stock: 17, sold: 15.

Example 2 :-

 <!DOCTYPE html>
<html>
<body>

<?php
$cars = array
  (
  array("Volvo",20,18),
  array("BMW",10,13),
  array("Alto",5,2),
  array("Land Rover",17,15)
  );
    
for ($row = 0; $row < 4; $row++) {
  echo "<p><b>Row number $row</b></p>";
  echo "<ul>";
  for ($col = 0; $col < 3; $col++) {
    echo "<li>".$cars[$row][$col]."</li>";
  }
  echo "</ul>";
}
?>

</body>
</html>
