datalength

This question is an exact duplicate of: PHP PDO Data_length always returns “0” 1 answer UPDATE 2: I kindly asked to unmark this question as duplicate as it is not a duplicate of the other question, which after some research I discovered the problem and provided an effective answer, which the person that marked my question as duplicate didn't provide stating that the code worked for him.

Well, I'm just trying the following for around two hours now and I can't get it to work. The following code will always return "0". Please, can anyone see where is the problem. This should work as a charm. And in PhpMyAdmin, when I run the statement it works correctly.

Yes that's exactly what you must do. If you want to just get number of characters excluding blanks you would

I cannot find this behavior documented anywhere. Does
