逗号分隔列表使用查询字符串中的括号

Question

I have a query string being sent to a php file as so: participants[]=111111111,22222222,333333333 etc....

If I remove the [] it functions fine, however, if I leave it in it ignores the array for each. How can I make PHP iterate through the comma seperated values with [] on the variable name? I tried explode which also failed unless I removed the []. I need to create a for each statement for the number of values returned for that var.

I have the following PHP code:

$participants = $_REQUEST["participants"];
foreach($participants as $i=>$value) {
    if($value > 1) {
        // define each variable
        $id = $_REQUEST['participants'][$i];
        print "$id<br />";
    }

}

I suggest using explode() in your code.
Since you can't remove the brackets in your query string, you may test the following code:

$participants = explode(',', $_REQUEST["participants"][0]);
foreach($participants as $i=>$value)
{
    if(intval($value) > 1) {
        // define each variable
        $id = $participants[$i];
        print "$id<br />";
    }
}

The output now is:
111111111
22222222
333333333
