Description:
------------
Actualmente estoy usando PHP 5.1.2 for win32 en windows 2k3, y experimento un bucle interminable.

Puede ser esto un bug ???

Saludos.

Reproduce code:
---------------
$db_res = db_query( $db, " SELECT * FROM clientes " ) ;

while ( $db_reg = db_fetch_array( $db_res ) ) {

   echo "1ro: " . $db_reg['cliente'] . "<br>" ;

   db_next( $db_res ) ;
   $db_reg = db_current( $db_res ) ;

   echo "2do: " . $db_reg['cliente'] . "<br>" ;

   db_prev( $db_res ) ; // aca esta el problema.

}


Expected result:
----------------
sumar un registro para verificarlo, y luego retroceder para seguir con el while. 

Actual result:
--------------
bucle interminable.

SORRY 2 :) !!!

all functions with prfix "db_" are equivalent to "sqlite_" functions. Rewrite the code.


$db_res = sqlite_query( $db, " SELECT * FROM clientes " ) ;

while ( $db_reg = sqlite_fetch_array( $db_res ) ) {

   echo "1ro: " . $db_reg['cliente'] . "<br>" ;

   sqlite_next( $db_res ) ;
   $db_reg = sqlite_current( $db_res ) ;

   echo "2do: " . $db_reg['cliente'] . "<br>" ;

   sqlite_prev( $db_res ) ; // aca esta el problema.

}

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc.

If possible, make the script source available online and provide
an URL to it here. Try to avoid embedding huge scripts into the report.


 [2006-01-21 22:39 UTC] tony2001@php.net
And try to describe the problem.

Tony : I speak Spanish :-)

He is trying to say, that the code above is getting into an infinite loop, however I think this bug is quite bogus.

to the OP:
you should read some tutorial like http://www.zend.com/php/beginners/php101-9.php

http://www.zend.com/php5/articles/php5-sqlite.php

and use sqlite extension in the Object oriented way. or even better, use pdo_sqlite.
 

if one of the suggested examples crashes for you please reopen this bug.

Feel free to reopen when you have a decent description and reproduce code.
