請用json_decode解析成數組
jsonp107({"SM_368_dsr-1097280647":{v:0,nv:100,m_UFB:0,m:4.89661,m_g:20.15,s_UFB:0,s:4.8744,s_g:31.49,c_UFB:0,c:4.87867,c_g:39.55,gp:100.00,ss:290167,hdr:true},"ICCP_1_522177046867":4915});


我要取4915這個值，請用json_decode解析成數組來取值。

求這幾行代碼
------解決思路----------------------

$s =<<< TXT
jsonp107({"SM_368_dsr-1097280647":{v:0,nv:100,m_UFB:0,m:4.89661,m_g:20.15,s_UFB:0,s:4.8744,s_g:31.49,c_UFB:0,c:4.87867,c_g:39.55,gp:100.00,ss:290167,hdr:true},"ICCP_1_522177046867":4915});
TXT;
$s = preg_replace_callback('/[-".\w]+/',
   function($m) { return '"' . trim($m[0],'"') . '"'; },
   preg_replace('/^.+\((.+)\).+$/', '$1', $s));
print_r(json_decode($s, 1));

Array
(
    [SM_368_dsr-1097280647] => Array
        (
            [v] => 0
            [nv] => 100

            [ss] => 290167
            [hdr] => true
        )

    [ICCP_1_522177046867] => 4915
)
