如何从mysql获取带变量的url参数？

Question

我有一个代码......就像这样......

$version = 2.0;
$customerid = 234;
$data = trim($row['signform']);  // this url string in mysql
echo $data;


//The browser result is
'version='.$version.'&customerid='.$customerid

我无法得到像

这样的结果

version=2.0&customerid=234 

但如果我设置

$version = 2.0;
$customerid = 234;
$data = 'version='.$version.'&customerid='.$customerid;
echo $data;

我明白了！

现在，我需要加载参数字符串包含$ variable，之前设置的值，然后浏览器显示字符串

version=2.0&customerid=234

Answer 1

$version = 2.0;
$customerid = 234;
$total_fee=100;
$data = trim($row['signform']);
$cc = eval("echo $data;");
echo $cc;

Resoved！
