Question

I have the following line of code that is throwing an error when used in PHP 5.3.1 and 5.3.8 and I presume all of 5.3.x. Only noticed it when I uploaded it to a server as it works fine on my local PHP 5.4.3

if (isset($args[0]['field_date']['und'][0]['value']['date'])) {
  // Do stuff
}

The error that is coming up is

Cannot use string offset as an array in my_module.module line 9

Answer 1

How are you initializing $args? You can’t use it as a string prior to performing array functions on it.
