[SOLVED] Debuggers

[Johnain]

Hi all

I have been working for the first time this week with PHP. I love it. I now have a bi-lingual web site with e-mails etc.

 

But now I have reached the point where Iwant to integrat a database using My SQL. I know SQL rasonably well, but I am not getting the results that I expect.  So this is the point where I need a debugger.

 

I downloaded and installed Gubed Release 0.2.0 onto my PC.It runs. But now is the point where I am overwhelmd by Techochat. Obviously I want to follow the steam on my hosting server. wheb I look into the Gubed help uder "installation" it says ...

 

"Copy the server scripts directory of the Gubed Archive to your webroot."

 

What scripts? What Archive?

What are you using a debugger for?

 

You know you can put a die statement at the end of your queries to catch errors, right?

$result = mysql_query($query)or die(mysql_error());

This sounds reall good.

 

Presumably this gives the MySQL message number? Would it give $reslut the value of that messag?

Here, read more about it here:

http://us2.php.net/mysql_error

 

It gives you the actual error, most of the times. If you spelled a field name wrong, it will tell you that the field doesn't exist. Sometimes it will give you a resource error...it just all depends.

Thanks a lot. I think I was looking for the comfort of a debugger from my experience of the horrific SAP ABAP/4 and slightly kinder vfp8.  I have got use to stepping through code and watching variable values.

 

I will mark this as solved now because I cannot work on this for two days and it's unfair to leave it open. But I will follow your link properly and use what it tells me.

 

Thanks again, really helpful.
