php 输出二进制数据流? - PHP / 基础编程

将要输出的二进制数据写入文件中，方便查看。

写入文件
PHP code:

$number = 123;
$handle = fopen ("data.dat", "w");
fwrite ($handle, pack ("L", $number));
fclose($handle);


读取数据
PHP code:

$handle = fopen ("data.dat", "rb");
$data = fread ($handle, 4);
$array = unpack ("L*", $data);
print_r($array);



如果我写入的是字符串，$number="中国人"
fwrite ($handle, pack ("L", $number));//pack 中存取方式改为 C/c 都无法正确的读取出来？
如果我要输出的数据流是一个数组怎么办？如：array("par1"=>array("sex","age"),"par2"=>array("ss","呵呵"))
怎样正确的输出为二进制数据
谢谢！

PHP code:

$arr = array ('a', 'b', array ("c", "d", "e"));
echo var_export ($arr);

/* ：
array (
0 => 'a',
1 => 'b',
2 =>
array (
0 => 'c',
1 => 'd',
2 => 'e',
),
)
*/
