The problem i have to get it to update. If i add this (see below) inside the

$update = UPDATE rocket SET PARTNO = '$results'';
mysql_query($update);
I know the answer is simple but i seem to be stuck on it.
I don't think you can just update a row that you just fetched within the
same query. If you do this in PHP, you should split the update into a
separate loop. Of course, it would be faster and more efficient to have
MySQL do it for you:
UPDATE rocket SET PARTNO = CONCAT('RU',PARTNO)

You can't use the character class \s within a range. And you need to

You should profile your code a bit more and see how much time getting
spent in your foreach loops and your usort(). You could always rewrite
your foreach loops into for loops and manually iterate through the array
itself instead of a copy. And you use strtolower() and trim() on every
pass through the data. That's a lot of work that can be pre-massaged in
the database so that you don't need to do it within your loops (granted,
this doubles your needed storage space in the hopes of speeding your
fuzzy searches).
Also, I noticed that your usort() was doing a normal numeric sort. That
being the case, why not switch the line:
usort($search_results, cmp);
and use:
sort($search_results, SORT_NUMERIC);

mysql_query() might fail, in which case it returns a boolean FALSE.
You should first check whether the query succeeded or failed.
$result = mysql_query($query);
if ($result === false)

Your if statement is wrong. You can't compare an array with a string.
And your $content_array is not guaranteed to exist when it reaches your

already have this knowledge via your $city_found variable. Use it.

There's two general ways to do data validation: client-side and server-side. PHP is server-side. JavaScript is client-side. With PHP, you allow the user to enter any data in the textbox, then code in logic to check for illegal characters (e.g. no letters in a textbox for one's phone number). Of course you must also code a nice response to let the user know when the data is found to be illegal, repost the form, etc. With JavaScript, you can do data validation as they press the submit button, or even disallow illegal characters as they type in a textbox. The response is far more immediate and thus far more effective, IMHO. Of course, if the user's web browser isn't running JavaScript, bad data may still slip through.

Nope. My pattern is legitimate. Within a range, if the first character
is a closing-square-bracket ']', it is treated as the literal character
and not as the end of range. If the range starts with a negation '^',
then the same rule applies to the second character.
This is also a sad indication that I really know my regular expressions,
or I need a vacation. :-)

Re: [PHP] strtotime bad logic or strtotime bug?

Bad logic. But it took me a while to figure it out. I'm glad I did;

: $start = date('Y-m-d', strtotime($start) + 86400);
: }
: ?
: END CODE--
It's a logic bug due to the wonderful world of Daylight Saving Time.
When the clock strikes 2003-10-26, adding 86400 seconds to calculate the
next day's timestamp is normally correct. However, that date is also
the last Sunday of Octobor when the U.S. officially reverts from
Daylight Saving Time back to normal time. Your next day's timestamp
loses one hour, i.e. 3600 seconds; your timestamp for 2003-10-27 12am
is now 2003-10-26 11pm. Because your date() call extracts only the date,
your truncation error is causing you to get stuck on 2003-10-26. This is
the cause of your infinite loop.
There are several ways to avoid this problem. The easiest way to change
date() to gmdate(). This gets you on UTC time, which is independent of
Daylight Saving Time or your timezone.
Hope this helps!

The last part of your pattern needs to be changed because it allows for

Also, the 2nd part of your pattern allows for a 2nd-level domain to
start and end with a hyphen, which is also disallowed.

That's due to PHP's automatic type conversion. In other words, certain
string values can get evaluated to either a boolean TRUE or FALSE. So
you have to do explicit tests.
For example, what does this code snippet do?
if ($_POST['test'])
{
do_right();
}
else
{
do_wrong();
}
If $_POST['test'] has an empty string, it calls do_wrong().
If $_POST['test'] has the string 0, it still calls do_wrong().
http://www.php.net/manual/en/language.types.boolean.php#language.types.boolean.casting
Your move to change your if-statement is a good start to doing the right
thing. The next step is to scrub your $_POST data and make sure that it
is valid.

Make a wrapper function instead that does the proper tests:
function print_field($field)
{
if (!empty($field))
{
echo $field . br\n;
}
}
Then change your code a bit:
td valign=top
?php echo $row_rsVandyDivAddresses['First_Name']; ?
?php echo $row_rsVandyDivAddresses['Last_Name']; ?,
?php print_field $row_rsVandyDivAddresses['Degree']; ?
?php print_field $row_rsVandyDivAddresses['Address']; ?
?php echo $row_rsVandyDivAddresses['City']; ?,
?php echo $row_rsVandyDivAddresses['State']; ?
?php echo $row_rsVandyDivAddresses['Zip']; ?
br
Phone: ?php print_field $row_rsVandyDivAddresses['Phone']; ?
Email: ?php print_field $row_rsVandyDivAddresses['Email']; ?
/td
You get the idea.
