关于二维数组。
zs,age=>10,sex=>nan),
(name=>zs,age=>10,sex=>nan),
(name=>zs,age=>10,sex=>nan),
(name=>ls,age=>11,sex=>nan),
(name=>ww,age=>12,sex=>nv),
(name=>ls,age=>11,sex=>nan),
(name=>ww,age=>12,sex=>nv),
(name=>ls,age=>11,sex=>nan),
(name=>ww,age=>12,sex=>nv)
);
echo '';
echo '数组转化为表格';
foreach( $group as $row ){
echo '';
foreach( $row as $col ){
echo '{$col} ';
}
echo '
';
}
echo '
';
?>

这样写为何不对？
------解决方案--------------------
$group = array(
array(name=>zs,age=>10,sex=>nan),
array(name=>zs,age=>10,sex=>nan),
array(name=>zs,age=>10,sex=>nan),
array(name=>ls,age=>11,sex=>nan),
array(name=>ww,age=>12,sex=>nv),
array(name=>ls,age=>11,sex=>nan),
array(name=>ww,age=>12,sex=>nv),
array(name=>ls,age=>11,sex=>nan),
array(name=>ww,age=>12,sex=>nv)
);
echo '';
echo '数组转化为表格';
foreach( $group as $row ){
echo '';
foreach( $row as $col ){
echo {$col} ;
}
echo '
';
}
echo '
';
