It is a hint that your method could be better, perhaps by dividing it into sub-methods. But this does not need to be followed to the letter and does not always mean that your code can be improved.
You can disable or configure these tips in:
- Tools -> Options -> Editor -> Tips (EN: Tools->Options->Editor->Hints)
- Choose the language in your PHP case
- Look for the 'Many lines' option (EN: "Too Many Lines") and set or uncheck the option to disable.

It seems that netbeans has some tool that checks the code, in which case it suggests that the method has 20 lines at most, other options may be checkspelling, minimum size in variable names etc.

Nothing to really worry about. Only a message the IDE generates from a setting that can parameterize into number of rows.
The idea behind this type of control has to do with some good development practice rules that the IDE implements or can help. One of them is that the smaller the number of lines in a function more effective this can be and better readability your code has.
To modify this behavior you can in: Tools->Options->Editor, on the tabulator Hints select "Too Many Lines" > "Function (Method) Declaration. Default is 20.

Every time someone gets a warning like that, they go to Hints that must be there the cause.
