Trying to access array offset on value of type null in-CodePudding

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

unset($ops_activos);
    unset($voices_activos);
    if ($on_pthelp == 1) {
        if ($ops["#pthelp"]['count'] > 0) {
            foreach ($ops["#pthelp"] as $value) {
                if (!is_int($value)) {
                    if (isset($ops_activos)) {
                        $ops_activos .= " " . $value;
                    } else {
                        $ops_activos = $value;
                    }
                } 
            }
            if ($bot_debug) {
                scmd("PRIVMSG ". $log_chan ." :[Membros (Mode)] [OPS]: ". $ops_activos);
            }
        }
        unset ($value);
        if ($voices["#pthelp"]['count'] > 0) {
            foreach ($voices["#pthelp"] as $value) {
                if (!is_int($value)) {
                    if (isset($voices_activos)) {
                        $voices_activos .= " " . $value;
                    } else {
                        $voices_activos = $value;
                    }
                    
                }
            }
            if ($bot_debug) {
                scmd("PRIVMSG ". $log_chan ." :[Membros (Mode)] [VOICES]: ". $voices_activos);
            }
        }

Line with error

if ($ops["#pthelp"]['count'] > 0) {

CodePudding user response：

You need to check the existance of the keys you have in the array before comparing as it can not find it anyway.

use this instead

if (isset($ops["#pthelp"]['count']) && $ops["#pthelp"]['count']> 0)

also for this will be good to avoid any further problems

if (isset($voices["#pthelp"]['count']) &&  $voices["#pthelp"]['count'] > 0)
