Wait until after the for loop has completed.
for ($i=0; $i $num_results; $i++) {
$variable[$i];
}
global $variable;
That's not going to work. The only thing that is doing is
making an already global instance of $variable global
within the function.
What you want is this instead:
$today = date(Ymd, mktime(0,0,0, date(m),date(d),date(Y)));
$last_week = date(Ymd, mktime(0,0,0, date(m),date(d)-7,date(Y)));
echo ($today - $last_week);
The result is a number like 8876 (20020107-20011231 = 8876)
But in date thinking it should be 7!
No, that's the difference in time
Consider the following:
$number = 102.52;
echo $number % 50;
echo bcmod( $number, 50 );
in both cases, it's spitting out 2. Why is it not spitting
out 2.52? Is there a way I can get that information?
w/o having to parse the string, breaking it up, getting
the modulus and then adding it back
I think it is $HTTP_SERVER_VARS['HTTP_REFERER']
Except that the value for this variable isn't always set and can
be spoofed. This value should not be relied upon.

you should know that $HTTP_REFERER can't be trusted. You

and so on. I'm trying to come up with a regex that will

This is untested, but something like...
$str = [hi] there, this is me [HI] there, this is me;
$newstring = ereg_replace((\[[A-Z]*]), br\\1, $str);
should do it.

$PHP_SELF?#FOO in the script, it all
It depends on where value is coming from. If it's coming from the

the client side, there may be other problems...
$value is defined in the server-side

Take a look at file(); and just loop through the resulting array
and removing all the blank elements.
what are you trying to do?
why do you want to diffirentiate between 99 as a string or
as a number?
Because if it is a string, more than likely it means that the key
was user defined and is not PHP defined as an element number.
Again, consider the differences between these two arrays:
Sample code:
script language=php
$array = array( one, two, three );
while( list( $key, $val ) = each( $array )) {
if( is_string( $key )) {
echo Key is a string\n;
}
echo Key: $key = $val :Val\n;
}
echo \n\n;
$array = array( SS = one, 15 = two, 19 = three
Then you can use:
if (mysql_num_rows($result) == 0) {
stuff here
}
This will check the number of rows returned from your query. If zero,
then do somethingmodify as you need.
What I generally do is this:
if(( !$result ) || ( mysql_errno() 0 )) {
// error code here
}
OR
if((

Or, so you don't have to specify all the variables you are using

One of the downside of PHP IMHO is, that you do not have to define
