for ($i = 0; $i <= $participants_names; $i++) {
print $i;
}
but i am not getting the result actualy i am from python and touching this first time in ,php so plz help me out where i am derailing .
$_GET['user_names'] is a string. You can use explode or split php function to make it an array.
If user_names is a comma-separated list of names :
$participants_names = explode( ',', $_GET['user_names']);
I think you can't simply pass a list as a parameter, you should serialize it. I suggest you to use JSON, which is supported by most browsers.
In JS pass this as parameter
"user_names="+JSON.stringify(user_names);
and in PHP use this
$participants_names = json_decode($_GET['user_names']);
Do a...
var_dump($participants_names);
... and se what it holds. I'm guessing it's something like a comma separeated list?
$list = explode(',', $participants_names); // Create an array named $list
for($i = 0; $i <= count($list); $i++) {
echo $i;
}
Try (assuming your user names are split by a semicolon)
$arrayUsers = explode(";", $_GET['user_names']);
foreach($arrayUsers as $user){
echo $user;
}
var usernames = ["A", "B", "C"]
data: "user_names="+ user_names.join(",") ;
$participants_names = explode(",", $_GET['user_names']);
