请教动态创建变量方法
- 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;
$_73 = 1;
如果数组为这样的
- PHP code
Array
(
[0] => 65
[1] => 66
[65] => Array
(
[$_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)
