Trace function PHP?

phpdino

Hi is there a trace function in php to display function calls, queries, and form submissions on that page when I submit? I seem to remember trace function but it's been a while. I'm just trying to track down what is being called and exactly happening with a this site. Any help would be greatly appreciated. Thanks!

[man]debug_backtrace/man and [man]debug_print_backtrace/man, perhaps?

I've been trying to use those but nothing yet. I'm looking at the examples but I don't know what I'm doing wrong. Can you post a little example on how I could use this say on a page with a form?

Not really sure what you're looking for, but you would call them at some point where you want to gather debug data. At the simplest, if you just want to echo it out to the current page:

if(something_went_wrong())
{
   echo "<pre>";
   debug_print_backtrace();
   echo "</pre>";
}

I'll keep working with this but I seem to remember a trace function that showed everything from database queries to all calls but this seems to show limited info. Maybe I was dreaming it 🙂

Thanks for your help!

I'm not aware of any single built-in PHP function that would do all of that. Perhaps you were using some user-defined function that included the backtrace info plus other functions like mysql_error(), etc.?
