Netbeans PHP断点变量值“评估......”

When I set a breakpoint in my PHP code I cannot see the content of a string variable because in the variables Value column it says "Evaluating...". What can be done to prevent this from happening? What is this, a timing problem? Can it be fixed with another setting?

I have seen this before but now I really need to know the value to find out my error.

I could isolate the problem and apparently it has to do with the result of PHP implode() that somehow takes too long or something.

I did not use Watches to evaluate the variable that was pending. I have no Watches and Balloon Evaluation set. I only use the Debug Variable display. I discovered that in my case the "Maximum Data Length" setting was too small. The variable value went beyond this limit. I was able to fix the issue by raising the limit.

Open netbeans, to to Tools -> Options -> PHP

When you use Watches, then make sure Watches and Balloon Evaluation is checked:

Also make sure that variables you want to evaluate don't hit the "Maximum Data Length" limit. Adjust this when necessary.
