I have a php bot (on IRC), and since I updated my php and mysql to the last version on CentOS I've come across with this error

PHP Warning: Invalid argument supplied for foreach() in stats.functions.php on line 71

Line 71:

foreach (isSet($nicks[$channel]) as $name => $value)

Code:

try
{
    global $db, $listas, $nicks, $channels, $time;
    $timeinc = time() - $time["inc"];
    $time["inc"] = time();
    $split = explode(",",$channels);
    foreach ($split as $channel)
    {
        if (!isset($channel))
        {
            continue;
        }
        if ($channel == "#pthelp")

CodePudding user response：

isset returns a boolean, so you cannot iterate through that. Move the isset to the if-check above, and just iterate through the array:

if ($channel == "#pthelp" && isSet($nicks[$channel]))
{
    foreach ($nicks[$channel] as $name => $value)
