新手求字符串转换成数组代码

Question

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))

Answer 1

$s = "*id=3,express_no=25,ename=quanri,*id=4,express_no=17,ename=kuaidi,";$t = array();
foreach(explode('*', $s) as $v) {
  if(empty($v)) continue;
  parse_str(str_replace(',', '&', $v), $t);
  $r[] = $t;
}
print_r($r);Array
(
    [0] => Array
        (
            [id] => 3
            [express_no] => 25
            [ename] => quanri
        )    [1] => Array
        (
            [id] => 4
            [express_no] => 17
            [ename] => kuaidi
        ))

Answer 2

$s='*id=3,express_no=25,ename=quanri,*id=4,express_no=17,ename=kuaidi,';
foreach(preg_split('/\*/',$s,-1,PREG_SPLIT_NO_EMPTY) as $k=>$v){
         foreach(preg_split('/,/',$v,-1,PREG_SPLIT_NO_EMPTY) as $vl){
         $arr=explode('=',$vl);
 $ar[$k][$arr[0]]=$arr[1];
 }
}
print_r($ar);Array
(
    [0] => Array
        (
            [id] => 3
            [express_no] => 25
            [ename] => quanri
        )    [1] => Array
        (
            [id] => 4
            [express_no] => 17
            [ename] => kuaidi
        ))
