php arrays

[Kevin Falcone <kevinfal@seas.upenn.edu>]

For those of us still curious about php arrays, I did the following
experiment.

Take the following code

    $fruits = array();
    $fruits['apple'] = 'red';
    $fruits['banana'] = 'yellow';
    
    echo "\$fruits is " . sizeof($fruits) . " elements long<br />";

    for ($i = 0; $i < sizeof($fruits); $i++) {
        echo "element $i of \$fruits is $fruits[$i] <br />";
    }    

    while ($x = each($fruits)) {
        echo "element $x[0] of \$fruits is $x[1] <br />";
    }

Run it, and you get

$fruits is 2 elements long
element 0 of $fruits is 
element 1 of $fruits is 
element apple of $fruits is red 
element banana of $fruits is yellow
