A Practical Model for Measuring Code Complexity of PHP

Abstract

Software quality metric for PHP is scarce in literature. This paper presents a technical and research overview of software quality assessment especially for software complexity to establish a software quality observatory for PHP language since PHP is one of the most popular languages that millions of websites and web applications are developed every month using PHP. Complexity is one important quality for software source codes. In this paper, software metric related to code complexity is investigated and a suitable set of metric is identified for the given system. Here, we present motivating examples, tool and techniques that can be used to evaluate the quality of source code. We have carried out an empirical study and tried to find out the nature of relationship between the metric and other well-known metric. In other words, it has been investigated whether complexity features may have positively or negatively on the code maintainability effort.
