It looks like index.php provides an example of how to use this code generator. I put the folder in my local htdocs folder and tried to access it. I get the following error message:
Parse error: syntax error, unexpected '{', expecting identifier (T_STRING) in C:\htdocs\crud\Class_.php on line 3
I would like to have a script like this, but until this is fixed I cannot know if it meets my needs.
