新手求字符串转换成数组代码
把字符串*id=3,express_no=25,ename=quanri,*id=4,express_no=17,ename=kuaidi,
转变成数组array(array(id=3,express_no=25,ename=quanri),array(id=4,express_no=17,ename=kuaidi))

------解决方案--------------------

PHP code

$s = "*id=3,express_no=25,ename=quanri,*id=4,express_no=17,ename=kuaidi,";

$t = array();
foreach(explode('*', $s) as $v) {
  if(empty($v)) continue;
  parse_str(str_replace(',', '&', $v), $t);
  $r[] = $t;
}
print_r($r);
