Re: [PHP] Addin a column of numbers not using MySQL
Do you mean something like:
?
$i = 0;
$sql = SELECT a,b,c FROM foo;
$res = mysql_query($sql);
while($myrow = mysql_fetch_array($res))
{
$i++;
echo $i.br /;
echo $myrow['a'] .br /;
echo $myrow['b'] .br /;
echo $myrow['c'] .br /;
}
?

Everything that you have been shown so far will do that. Is it possible

wrong. Try it with single quotes;

Re: Re: [PHP] Addin a column of numbers not using MySQL
Give an example db layout and/or array layout that you plan on using.
Would I be correct in assuming that the array would look something like
this?
$values['val_1'] = 100.00;
$values['val_2'] = 150.00;
$values['val_3'] = 200.00;
$values['val_4'] = 250.00;
$values['val_5'] = 100.00;
if this is correct you could do something like this.
$t=0;
foreach($values AS $amnt)
$t += $amnt;
echo $t; // this should return 800
if you wanted the formatted return to be something like xxx.xx you'll want
to use something like number_format()
if for some reason you are getting it from mysql then it could look like the
following.
$sql = SELECT title, val FROM tbl;
$results = mysql_query($sql);
$t=0;
while($row = mysql_fetch_assoc($results)) {
$t += $row['val'];
}
echo $t;
Maybe you have a different style sql statement.
$sql = SELECT SUM(val) FROM tbl;
$results = mysql_query($sql);
list($t) = mysql_fetch_row($results)) {
echo $t;
Notice the difference in mysql_fetch_* functions
if you want the second sql statement used but want to refer to it by a name.
do this
$sql = SELECT SUM(val) AS total FROM tbl;
$results = mysql_query($sql);
$arr = mysql_fetch_assoc($results);
echo $arr['total'];
If i confused you with all the different ways to do this, don't worry, I
confused myself also.
If need be, I will explain more.
