Array
(
    [0] => 65
    [1] => 66
    [2] => 71
    [3] => 73
    [65] => Array
        (
            [$_65] => 0
        )

    [66] => Array
        (
            [$_66] => 0
        )

    [71] => Array
        (
            [$_71] => 0
        )

    [73] => Array
        (
            [$_73] => 1
        )

)

有如上变量，请问如何动态创建4个变量
$_65 = 0;
$_66 = 0;
$_71 = 0;
$_73 = 1;

如果数组为这样的

Array
(
    [0] => 65
    [1] => 66
    [65] => Array
        (
            [$_65] => 0
        )

    [66] => Array
        (
            [$_66] => 0
        )

)

则创建这样的
$_65 = 0;
$_66 = 0;

------解决方案--------------------

PHP code

$ar=Array ( 
    '0' => 65 ,
    '1' => 66 ,
    '65' => Array ( '$_65' => 0 ) ,
    '66' => Array ( '$_66' => 0 ) 
) ;
foreach($ar as $v){
     if(is_array($v)){
         foreach($v as $kl=>$vl) eval("$kl=$vl;");
     } 
}

var_dump($_65,$_66);  //int(0) int(0) <div class="clear"></div>
