</blockquote>
Plugin Check is a developer tool. It scans the plugin or application you specify (or upload) and determines whether you have undefined functions or methods in it.
PHP is not a compiled language. It looks for functions during runtime. So if you have a segment of code not covered by your normal testing, and you have an undefined function in there, you will never know of the undefined function until it hits production when the particular conditions activating that particular code segment are met. This tool will prove especially useful during large scale refactoring, or for quality checking for submission to sites like CodeCanyon.
<blockquote>

Plugin Check

Pro version is great!
It's worth every penny + Manoj quick with his help too.
Thank you so much!



Pro version is great!

Pretty good design. The results are aren't very clear though. No need to show the "The auto-generated code is:" section. With a little more work this could be great.



Pretty good.

Not working.
