Too many parsing, exploding, regex, strcomp, strpos and string manipulation functions.
TL;DR: Use real abstractions and real objects instead of string accidental manipulation.
Problems

Complexity
•
Readability
•
Maintainability
•
Lack of Abstractions
Solutions
1) Work with objects instead.
2) Replace strings with data structures dealing with object relations.
3) Go back to Perl :)
4) Find Bijection problems between real objects and the strings.
Examples
-Serializers
-Parsers
