$a=array(“5″,”8″,”7″,”1″,”0″,”2″,”9″);
print_r($a);
echo”<br />”;
foreach($a as $value)
{
    echo “\$a的当前值为:$value!<br />”;
}

/*带下标*/
$i=1;
foreach($a as $v)
{
    echo”\$a[$i]的值为:$v.<br />”;
    $i++;
}

/**/
foreach($a as $b=> $v)
{
    echo”\$a[$b]=$v<br />”;
}

/*多维数组应用*/
$c[0][0]=”My”;
$c[0][1]=” is”;
$c[1][0]=” Horleun”;
$c[1][1]=”.<br />”;
foreach($c as $v1)
{
    foreach($v1 as $v2)
    {
        echo”$v2″;
    }
}
?>

结果:
