 Hi,
 Is it possible that I would get the wrong ID (Not the ID I just inserted
in
 Auto_Increment field) by using mysql_insert_id function if someone is also
 inserting record at the same time? How does mysql_insert_id work
accurately?

 Thanks,
 Wee

You can get the last auto_inc with the following query:
SHOW TABLE STATUS 'my_table_having_an_autoinc'
and then lookup the field Auto_increment in the result set.

Best regards

Christian

[PHP] Function call stack

[Christian Novak]

Has anyone an idea on how to get information from PHP on the function call
stack.
I need the line number and file calling a function for a custom error
handler.

To be more clear, here is what I would like to do:

- I have a library, included in the main program
- I have an error handler in the library

// main.php
require library.php;
$x = myfunc('A');


// library.php
function myfunc($i)
{
if (!is_int($i)) {
   $file =   // how can I get the file name of the file
calling myfunc()
   $line =  // how can I get the line number of the file
calling myfunc()
   trigger_error(Error in  $file, at line $line, paramter must be an
integer!, E_USER_ERROR);
return($i);

Using the pre_defined varibales __line__ and __file__ will always point me
to the function not the calling
script.

Best regards

Christian Novak
