<p>遍历和打印数值数组的值：</p>
<p><?php<br> $cars=array("Volvo","BMW","Toyota");<br> $arrlength=count($cars);<br><br> for($x=0;$x<$arrlength;$x++)<br> {<br> echo $cars[$x];<br> echo "<br>";<br> }<br> ?></p>

<blockquote>
<p>遍历和打印关联数组的值：</p>
<p><?php<br> $age=array("Peter"=>"35","Ben"=>"37","Joe"=>"43");<br><br> foreach($age as $x=>$x_value)<br> {<br> echo "Key=" . $x . ", Value=" . $x_value;<br> echo "<br>";<br> }<br> ?></p>

<blockquote>
<p>创建多维数组：</p>
<p><?php<br> // 一个二维数组<br> $cars=array<br> (<br> array("Volvo",100,96),<br> array("BMW",60,59),<br> array("Toyota",110,100)<br> );<br> ?></p>
