Re: How to take output from an include, and embed it into a variable?

Output buffering will do it.
Also I am not sure but did you try retrieving content with fopen() ?
Something like
$file = 'invoicetable_bottom.php';
fopen(http://yoursite.com/folder/$file,r;);
http://tr.php.net/function.fopen
worth trying. Easier than output buffering

Hi,
The simplest way (actually the single way I know :) ) would be to
capture the output using output buffering functions, something like this:
// start output buffering
ob_start();
// include the file that generates the HTML (or whatever content)
include ;
// get output buffer content
Morning!
Just a quick question.
Say I have a column in my database that could contain NULLS, empty spaces,
or an actual value.
If I do:
$my_query = SELECT my_column FROM my_database WHERE 1 = 1;
$my_result = ifx_query($my_query, $connect_id);
while($row = ifx_fetch_row($my_result)) {
Use var_dump before processing your result.

using empty() is ´the right way to check a var for NULL or
however, it also depends what MySQL has got as setuo definition for empty
fields. on textfields u can define an epmty string as default.

Empty will also match a string containing 0. And, to me, that doesn't at
all seem empty :)

if it can take only numeric values u can use is_numeric()
also i suggest that you not to use nulls in dbs. instead, use not null and
default value property. Its more simple and more effective for both managing
your database and coding your program.

This might help some people struggling with memory leak problems in
DOMPDF. I haven't fixed it but it seems to have reduced the memory leak
considerably.

I'm have trouble with a simple HTML Checkbox list. I keep getting *Parse

simple and basic wrong I just cannot seem to see what it is, any assistance
is appreciated.

If this is correct, why not do it in the SELECT statement to begin

$my_query = SELECT my_column

Easier in what sense? It would end up requiring more code than
output-buffering because you'd have to read from the file after
calling

Hello,
I just spent way, way to much time trying to debug code due to a misnamed
element. Here is a simplified example of the problem I dealt with.
$test = SELECT * FROM `Materials` WHERE `Part_Number` = '125664';
$result = mysql_query($test,$handle);
if(!$result)
Hi,
There is, see here (or it can also be set through php.ini):

You are looking for E_STRICT.

I think he meant that he is using 'Number' instead of 'Part_Number'
when accessing the array and not in the SQL, his SQL was correct, this
was wrong:
echo $row['Number'];
E_STRICT catches that kind of error.

I think the problem is that he didn't check that the key he used
actually existed before using the value it pointed to. So he got an
empty string for $row['Number']; because the key should have been
'Part_Number'. I don't know that even E_STRICT would catch that one.

there's a need for long timeouts in this app but could perhaps be reduced
from 6 to 3 hours.
the sessions are cookie based using php's 'file' handler and
session.cookie_lifetime=0. the server appears to have plenty of free memory
and appears not to have swapped in nearly a year of uptime. load
finaly we went with a custom cooky handling, however the customers
requirements where two days.
if u are shure that the server is still the same hardware like it has been 6
years ago then it might be some client stuff, however if there are other
applications, pages running (virtual servers) then

Better use mysqli rather mysql. It supports all new features of MySQL.
I solved the problem in following manner.
1. Detect the return value of mysqli-query function.
2. If it is FALSE get the error no, error msg etc and store in a Mysql table
for further review. You can also write it in a error
