It’s quite strange to see how the whole PHP ecosystem has changed over the years, no longer does the employee need to convince the employer that he is a good developer; tables have turned, and finding good PHP developers is getting tougher by the day.
Enough about the current state of PHP, what about some tools that can help us to analyze and parse our code so that we may avoid encountering problems and issues during our coding time? Here is a list of the most popular tools according to developers themselves.
PHP Parser is a code parsing project that’s built on top of PHP; intended for the PHP versions from 5.2 to 5.6. This particular parser is great for dong static analysis, and it enables you to manipulate the code of any applications that’s dealing with code in a programmatic way. The parser works through Abstract Syntax Tree (AST).
A full-scale PHP 5.3.2+ sandbox class that utilizes PHP-Parser to prevent sandboxed code from running unsafe code. So, this one and the one above go hand in hand. Some of the features that stand out include the ability to redefine your internal PHP code to make it more secure and friendly for using in a sandbox. Here is the page that documents the whole process.
