It is a JSON String, You have to decode it first using Json_decode

    $regData = '{"student":"699","eposter":"99","exhibitor":"1199","Single-2-nights":"400"}';
    $arrayData = json_decode($regData,true);
    $selected ='';
    foreach($arrayData as $key => $value){
    $selected .= $key." :". $value."<br/>";
    }

$regData = '{"student":"699","eposter":"99","exhibitor":"1199","Single-2-nights":"400"}';
print_r(json_decode($regData));

will result an object

Hi Ganesh I Checked your code, your foreach loop syntax is fine but It's a better practice to write endforeach; at the end of loop + in your array replace : with =>

$regData = ["student" => "699",
            "eposter" => "99",
            "exhibitor" => "1199",
            "Single-2-nights" => "400"];

in php, array should be in square brackets

foreach($regData as $key => $value){  
    $selected .= $key." :". $value."<br/>";  
}

Foreach code is OK.
