Array in PHP

PHP Indexed Arrays

<?php
$s = array("Ku", "Su", "Yu");
echo "I like " . $s[0] . ", " . $s[1] . " and " . $s[2] . ".";
?>

PHP Associative Arrays

<?php
$age = array("Peter"=>"35", "Ben"=>"37", "Joe"=>"43");

foreach($age as $x => $x_value) {
    echo "Key=" . $x . ", Value=" . $x_value;
    echo "<br>";
}
?>

Result: Key=Peter, Value=35

Key=Ben, Value=37
Key=Joe, Value=43

Multidimensional Arrays

<?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>";
?>

Result:

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.

PHP Mail Function

$title='Test';
     $body = ' "';
$from='info@test.com';


  $headers = 'From: '.$from.'' . "\r\n" .
              'Reply-To: '.$from.'' . "\r\n" .
  'BCC: '.$from.''. "\r\n" .
 
  'Content-type: text/html; charset=utf-8' . "\r\n" .'X-Mailer: PHP/' . phpversion();
 
              //put your email address here
              mail($email, $title, $body, $headers);
