2维数组为什么只输出一个?

<br />
	<?php<br />
<br />
		$foodPrices = array(<br />
			"vegetable" => array("potato" => 1.00, "onion" => .50),<br />
			"fruit" => array("apple" => 2.50, "orange" => 2.00)<br />
		);<br />
<br />
		foreach($foodPrices as $category)<br />
		{<br />
			foreach($category as $food => $price);<br />
			{<br />
				$f_price = sprintf("%01.2f", $price);<br />
				echo "$food: \$$f_price <br>";<br />
			}<br />
		}<br />
	?><br />


输出只有
onion: $0.50
orange: $2.00 

为什么会少一个
------解决方案--------------------
foreach($foodPrices as $category)
    {
        foreach($category as $food => $price)   //这一行多个分号
        {
            $f_price = sprintf("%01.2f", $price);
            echo "$food: \$$f_price ";
        }
    }
------解决方案--------------------
foreach($category as $food => $price);
这里多了个分号;
------解决方案--------------------
第二个foreach后面有 ; 分号。
ok??
------解决方案--------------------
foreach($category as $food => $price);
