分隔字符串，有点难度哦

[crazyboy2005]

$str = "html='<a id=\'test\'>hello,world</a>', name='jiang, lin', year=12, x1=3, mb='slink', mx='hiang'";

如何将其中的值分离成下面的键值对：
html='<a id=\'test\'>hello,world</a>'
name='jiang, lin'
year=12
x1=3
mb='slink'
mx='hiang'

谢谢各位不吝赐教

这个不是很烦。转几次应该可以出来的。

$str = "html='<a id=\'test\'>hello,world</a>', name='jiang, lin', year=12, x1=3, mb='slink', mx='hiang'";

$ch = ', ';
$r = array();
$t = '';
foreach(explode($ch, $str) as $v) {
  if(substr_count($t, "'")%2) {
    $t .= $ch.$v;
    continue;
  }
  if($t) $r[] = $t;
  $t = $v;
}
if($t) $r[] = $t;

print_r($r);

Array
(
    [0] => html='<a id=\'test\'>hello,world</a>'
    [1] => name='jiang, lin'
    [2] => year=12
    [3] => x1=3
    [4] => mb='slink'
    [5] => mx='hiang'
)

$str = "html='<a id=\'test\'>hello,world</a>', name='jiang, lin', year=12, x1=3, mb='slink', mx='hiang'";
preg_replace("/([\w]+)=(.*?)(?=(,\s*[\w]+=|$))/ie", "\$arr['\\1']='\\2'", $str);
print_r($arr);

或者不要'

$str = "html='<a id=\'test\'>hello,world</a>', name='jiang, lin', year=12, x1=3, mb='slink', mx='hiang'";
preg_replace("/([\w]+)=([']?)(.*?)\\2(?=(,\s*[\w]+=|$))/ie", "\$arr['\\1']='\\3'", $str);
print_r($arr);
/*

Array
(
    [html] => <a id=\'test\'>hello,world</a>
    [name] => jiang, lin
    [year] => 12
    [x1] => 3
    [mb] => slink
    [mx] => hiang
)

*/

[一起混吧]

$str=preg_replace("/, (?=\w+=)/",'&',$str);
parse_str($str,$ar);
print_r($ar);

Array
(
    [html] => '<a id=\'test\'>hello,world</a>'
    [name] => 'jiang, lin'
    [year] => 12
    [x1] => 3
    [mb] => 'slink'
    [mx] => 'hiang'
)
