Let me rephase my question in my previous email:
I'd like to compare 7 strings(which are in an array). Each string should be
the same, if they are not, a message should be outputted. How would one do
this outside of using a huge if/then statement?
Thanks,
Brent

Subject: [PHP] String compare of 7 text strings
I wanted to see if anyone has an easier way to do this. The end result is
this: I need to compare 7 different text strings(which are in an array).
They should all be the same, if they are not the same, a message should be
outputted saying they weren't.
How would one do this outside of using a huge if/then statement?
Thanks,
Brent

// Not all fields in the array are the same...

How does one get the size of a mysql table using php? I tried taking a look at how
phpmyadmin does it but got lost in the code. Anyone have any simple or elegant ways of
doing this?
-Thanks

show table status like 'table_name';
size = Data_length + Index_length

Hello Professionals,
Can anybody help me to open all subdirectories in a directory,
I used is_dir() to check whether it is a dir, and if yes,
I recursively called it with the new dir name.
But all subdirectories are not open the recursion is not working for more
than 1 level.
I tested it in windows server.
Expecting your help,
Jacob.

Try to call is_dir() with full/path/to/dir ( realpath() may come in handy ) and/or
chdir() to the dir.

Have you looked at the opendir manual page to see if there are any
examples, there?

Is the str_replace function case sensitive, I cant seem to find any
answer on the PHP manual website or in my books.
If it is, is there anyway to make it case insensitive so it can handle
mIxEd CaSe woRdS in any combination?
Thanks

Yes. For case in-sensitve use str_ireplace
Look at the PHP manual one more time under "See also"

Hi,
I have a quick question about using the PHP die() function. I'm building a
site around a MySQL database, and when I connect to the database from a PHP
page I use the following code:
$connection = mysql_connect($host, $user, $password)
or die("Error connecting to SQL server");
$db = mysql_select_db($database, $connection)
or die("'Error connecting to database");
Simple enough so far right? So if there is a problem connecting in anyway,
an error message appears. What I want though is to redirect to a properly
separate error page, rather than just have a basic text mesage.
I changed the code to this:
$connection = mysql_connect($host, $user, $password)
or die("Error connecting to SQL server");
$db = mysql_select_db($database, $connection)
or header('Location: ../errors/databaseselect.php');
Which works fine (tested by deliberately misnaming database so it can't find
it).
However if I then use the same approach for the server connection error,
like below, it doesn't work.
$connection = mysql_connect($host, $user, $password)
or header('Location: ../errors/servererror.php');
$db = mysql_select_db($database, $connection)
or header('Location: ../errors/databaseselect.php');
I get a variety of error messages dependant on what I tweek to try and make
it work. I've tried all I can think of, and I've tried putting the header
function inside a die function to no avail. I don't understand why it works
for the database connect error but not the server error.
If anyone has any suggestions as to what the problem is or how I could
improve my technique I'd love to know. I'm sure I can't be the only person
who has wanted to do something like this, but I can't find any references
online to anything other than simple text error messages. I'm relatively new
to PHP but not programming in general so please don't be afraid to fire big
words at me.
Thanks in advance!
John G
