Looping Through Array Keys and Values

title:: Rear Window
director:: Alfred Hitchcock
year:: 1954
minutes:: 112


<?php

$movie = array( "title" => "Rear Window",
                "director" => "Alfred Hitchcock",
                "year" => 1954,
                "minutes" => 112 );

echo "<dl>";

foreach ( $movie as $key => $value ) {
  echo "<dt>$key:</dt>";
  echo "<dd>$value</dd>";
}

echo "</dl>";

Counting Multidimensional Arrays


<?php

$movieInfo = array( "directors" => array( "Alfred Hitchcock", "Stanley Kubrick", "Martin Scorsese", "Fritz Lang" ),
                    "movies" => array( "Rear Window", "2001", "Taxi Driver", "Metropolis" ) );

// Displays "2"
echo count( $movieInfo );
?>

Accessing Elements in Multidimensional Arrays

six


<?php
$myArray = array(
  array( "one", "two", "three" ),
  array( "four", "five", "six" )
);

// Displays "six"
echo $myArray[1][2];
?>

Accessing Elements in a Multidimensional Array

The title of the first movie:
Rear Window

The director of the third movie:
Martin Scorsese

The nested array contained in the first element:
Array ( [title] => Rear Window [director] => Alfred Hitchcock [year] => 1954 )


<?php
$movies = array(
  array(
    "title" => "Rear Window",
    "director" => "Alfred Hitchcock",
    "year" => 1954
  ),
  array(
    "title" => "Full Metal Jacket",
    "director" => "Stanley Kubrick",
    "year" => 1987
  ),
  array(
    "title" => "Mean Streets",
    "director" => "Martin Scorsese",
    "year" => 1973
  )
);

echo "The title of the first movie:<br />";
echo $movies[0]["title"] . "<br /><br />";

echo "The director of the third movie:<br />";
echo $movies[2]["director"] . "<br /><br />";

echo "The nested array contained in the first element:<br />";
print_r( $movies[0] );
echo "<br /><br />";
