PHP怎么实现输出数组变量?
$html['result'] = '1111111111';
$arr = [
'urls'=>"html['result']"
];
$temp = $arr['urls'];
代码不变,怎么能过$arr输出“1111111111”

$html['result'] = '1111111111';
$arr = [
'urls'=>"html['result']"
];
$temp = $arr['urls'];
$urls = $html['result'];
echo $$temp; // 输出 "1111111111"
$html['result'] = '1111111111';
$arr = [
'urls' => "\$html['result']"
];
$temp = $arr['urls'];
eval("\$temp = $temp;");
echo $temp; // 输出结果:"1111111111"
$html['result'] = '1111111111';
$arr = [
'urls' => 'html',
];
$temp = null;
// 使用反射获取数组的值
$reflection = new ReflectionClass($arr['urls']);
$property = $reflection->getProperty('result');
$temp = $property->getValue($html);
echo $temp;
$html['result'] = '1111111111';
$arr = [
'urls'=>"html['result']"
];
$temp = $arr['urls'];
function getValue($str) {
global $html;
preg_match("/\['(.*)'\]/", $str, $matches);
return $html[$matches[1]];
}
echo getValue($temp); // 输出 "1111111111"
