maybe somebody else will be able to come up with a
much more graceful solution to this, but i think you
need to forget unset()-- all it does is destroy a var
within a script. your db data doesn't become a var
until you fetch it, but unset() isn't a mysql function
and doesn't interact with the db a

if you're just looking for the 1st occurrence of the
string, it's--
$check = "good";
$var = "This is a good...";
if (!strstr($var, $check)) {
print("$check not found");
}
also, i think strstr() is case-insensitive, so it
won't be able to differentiate between 'Good' and
'good', and will NOT ret
do you mean, as in,
if !is_integer($var) {
print("$var is not an integer");

problems--
1st, the function is mysql_query()
2nd, the query is built like this:
$connection = mysql_connect('host', 'user', 'pass');
$db = mysql_select_db('db', $connection);
$query = "SELECT * FROM tablename WHERE primary_key =
'$primary_key'
I am working on a form that needs to run INSERTS into
a table, but also has other connections and functions
going on, so $php_self isn't really an option (I'm a
newbie, and switch still scares me)...
Can I effectively use an include/require(insert.php)
on the main of the form, have the form actio
Hi,
How do I call on a switch from within an html-embedded
page?
Say I have a large php script that first verifies a
login, then allows templates for INSERTING, UPDATING,
& DELETING various records-- I need to have separate
templates load for each set of steps, but I only have
the vaguest of id

ugly form with a text input field that is focussed when the form loads,
