Hi,
My question is about the norlmal behaviour of PHP and MYSQL but I cant
explain it without a simple example. Thank you for reading:
I have the following code:
--------------------------------------------------------------------
<?php
print $t = $_POST['txt'];
print $t = addslashes($t);
@ $db = mysql_pconnect(xxx,xxx,xxx);
mysql_select_db('test');
$q = "update ttable set ffield='$t'";
mysql_query($q);
$q = "select * from ttable";
$result = mysql_query($q);
$bo = mysql_fetch_array($result);
print $t = $bo['ffield'];
print $t = stripslashes($t);
?>
--------------------------------------------------------------------
from a HTML form I send variable:
--------------------------------------------------------------------
' \ \' \\ \\\
--------------------------------------------------------------------
after addshashes it becomes:
--------------------------------------------------------------------
\' \\ \\\' \\\\ \\\\\\
--------------------------------------------------------------------
after that it gets in the database
but after I get it out it becomes:
--------------------------------------------------------------------
' \ \' \\ \\\
--------------------------------------------------------------------
(without the backslashes!)
and ofcourse after stripslashes it gets messed-up:
--------------------------------------------------------------------
' ' \ \
--------------------------------------------------------------------
So my question is if this is a normal behaviour for PHP+MYSQL or it may vary
indifferent conficurations or versions of both php or mysql.
It's not a bad thing to be like that but I wonder if my code will behave the
same at most systems.
Thank you very much
