strlen of a non existing variable in PHP

+1 vote
50 views

I have a code in PHP something like this

 if (strlen($profile['current-employer']) == 0)
     break;
 else
     return a;

Now in some cases $profile['current-employer'] can be non-existent, now here my question is in the case of non-existent variable what strlen will result... (This is related with QueryHome code)

Trying to manage line breaks in some output I'm generating and using strlen to measure the lengths of the strings I'm printing. Discovered something strange (to me!) in that strlen is returning +1 more than it
should.

The strings are from a query of my database - simple name fields. But everyone of them is coming back with a length that is one more than I see.
