Recursive count() example

$food = array('fruits' => array(’orange’, ‘banana’, ‘apple’),
‘veggie’ => array(’carrot’, ‘collard’, ‘pea’));

// recursive count
echo count($food, COUNT_RECURSIVE); // output 8

// normal count
echo count($food); // output 2

?>

I wrote up this quick little banking script to illustrate how to do simple object oriented programming in php5 using classes. Functions within a class are known as methods.

-JJ

class account_transact
{
    var $balance;
    var $account_type;
    var $amount;

    function get_bal($account_type)
    {
        if($account_type=='checking')
        {
            #query for sql to look up account
            $balance=100;
        }
        elseif($account_type=='savings')
        {
            #query for sql to look up account
            $balance=25;
        }
        return $balance;
    }
    function verify_account($account_type)
    {
        if($account_type=="checking" || $account_type=="savings")
        {
            #account verified
            return $account_type;
        }
        else
        {
            echo $account_type." is not a valid account";
            exit();
        }
    }
    function deposit($account_type, $amount)
    {
        $cur_bal=$this->get_bal($account_type);
        $new_bal=$cur_bal+$amount;
        print "Balance for “.$account_type.” is $”.$new_bal.”
“;
    }
}

//create new class instance
$transaction=new account_transact();

//checking deposit
$account=$transaction->verify_account(”checking”);
$transaction->deposit($account,”5″);

//savings
$account=$transaction->verify_account(”savings”);
$transaction->deposit($account,”-10″);
?>

PHP

Standard php conditional:

1. if (date("G") < 12) {
2. echo 'Good morning';
3. } else {
4. echo 'Good afternoon';
5. }

Shorthand…

1. $greeting = (date("G") < 12) ? 'Good morning' : 'Good afternoon';
2. echo $greeting;
