請問動態建立變數方法

請教動態建立變數方法

PHP code

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        ))

有如上變數，請問如何動態建立4個變數
$_65 = 0;
$_66 = 0;
$_71 = 0;
$_73 = 1;

如果數組為這樣的

PHP code

Array(    [0] => 65    [1] => 66    [65] => Array        (            [$_65] => 0        )    [66] => Array        (            [$_66] => 0        ))

則建立這樣的
$_65 = 0;
$_66 = 0;

------解決方案--------------------

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)
