正则表达式不在PHP中的括号之间打印字符串

I have researched this up and down am can't figure out what I'm doing wrong. I have the following variable which I get from $_GET.

$monitorname = $_GET['monitorname'];

which should look something similar to: 985_Sands-Road(54dd14d80bd5f777184cb9c8), in the URL it actually looks like:

index.php?monitorname=985_Sands-Road%26%2340%3B54dd14d80bd5f777184cb9c8%26%2341%3B&alertType=0"

I'm trying to use Regex to get the text between the parentheses, here is my regex code:

preg_match('/\(([^)]+)\)/', $monitorname, $match);
$id = $match[1];
echo $id;

However no matter what I do, it won't echo the ID. What can I look at and fix in this? It must be noted that when I save the string explicitly as a variable it works fine:

$text = '985_Sands-Road(54dd14d80bd5f777184cb9c8)';
preg_match('/\(([^)]+)\)/', $text, $match);
$id = $match[1];
echo $id;

Thanks so much in advance

    $monitorname = $_GET['monitorname'];
    $src=array('(',')');
    $rep=array('(',')');
    $monitorname=str_replace($src,$rep,$monitorname);
    
    //now your code
    
    preg_match('/\(([^)]+)\)/', $monitorname, $match);
    $id = $match[1];
    echo $id;
    

    My first thought was urldecode() too, but it doesn't work in this case...
