php如何输出二维数组,PHP中以不同形式的输出遍历二维数组 方法

$arr = array(

array("101","李军","男","1976-02-20","95033"),

array("103","陆君","男","1974-06-03","95031"),

array("105","匡明","男","1975-10-02","95031"),

array("107","王丽","女","1976-01-23","95033"),

array("108","曾华","男","1977-08-01","95033"),

array("109","王芳","女","1975-02-10","95031"));

第一种输出形式(echo语句)/* echo "

echo "

SnoSnameSsexSbirthdayClass";

foreach($arr as $v){

echo "

{$v[0]}{$v[1]}{$v[2]}{$v[3]}{$v[4]}";

}

echo "

" ;

第二种输出形式(HTML代码 表格输出)

foreach($arr as $v){

echo "

{$v[0]}{$v[1]}{$v[2]}{$v[3]}{$v[4]}";

};

?>

第三种输出形式(下拉列表)

$arr = array(

array("1","山东"),

array("2","北京"),

array("3","上海"),

array("4","广州"),

array("5","香港"),

array("6","澳门")

);

?>

请选择

foreach($arr as $v){

echo "$v[1]";

};

?>

第四种输出形式

取数组中输出的总数

$arr = array(

array(4)

);

echo $arr[0][0];

取数组中一组数据

$arr = array(

array("1","上海")

);

echo "{$arr[0][1]}";

取数组中任意一个数据

$arr = array(

array("1","台湾"),

array("2","北京"),

array("3","上海"),

array("4","广州"),

array("5","香港")

);

echo "{$arr[4][1]}";

?>
