PHP Debugging Tools
  • Krumo

    Krumo is one of the popular debugging tools. It allows PHP programming to display well-constructed information for any variable. While Krumo is an alternative to print_r() and var_dump(), it uses CSS/HTML/JS to display information. The following are some excellent features of this debugging tool.

    • It presents structured and organized information via the stack.
    • Developers can use this tool to add variables to a stack with a simple function call.
    • It uses CSS and DHTML to print out a stack of variables to make it more human-readable.

    Caution! Like any other tool and technology, Krumo is not free from disadvantages. For example, heavy HTML comes at a high memory cost. Plus, it is too flexible because of its hardcode.

  • Kint

    Rather than a debugging tool, it is more appropriate to call Pinba a MySQL plugin. It is a free real-time monitoring server that allows PHP developers to track the performance of PHP scripts and locate bottlenecks. Below, we have listed features of Pinba that make it an excellent debugging tool.
