PHP Illegal String Offset Warning on Array

Question

I get illegal string offset warning from the array inside if statement

411.  if (is_array($attrib['affixes'])) { // merge
412.     $new_affix = array_merge($attrib['affixes'], $new_affix);
413.  }

Exactly the warning is

"Warning: Illegal string offset 'affixes' in C:\xampp\htdocs\pengakar-master\src\Pengakar.php on line 411"

I insert the full code below :

Another part is alright. Only that part that get the error

Thanks for the help.

At first check that $attrib array contains element with key affixes through theisset() or array_key_exists(). — Timurib

The illegal offset means that the index your are referencing does not exist. So, in this case the 'affixes' index of the array is never defined. To prevent the error, change the code as follows:

if (isset($attrib['affixes']) && is_array($attrib['affixes'])) { // merge
    $new_affix = array_merge($attrib['affixes'], $new_affix);
}
