I create a png dynamically - store the path in mysql.
And want to be able to offer the user a zipped version to download
Unfortunately haven't been able to get it to work up until now !
I'm sure it's something obvious but...
Open the png
$data = fopen('kunden/'.$name.'.png', rb);
I'm new to the PHP and Mysql world and I hope I have an problem that can be
answered quickly. It seems simple but who knows.
Whenever I try to use cookies or start a session I get the following error:
Warning: open(/Temp\sess_ba759cb3d78fadb70745ca480f1d8661, O_RDWR)

Yes, it is.
the return value of fopen is a resource of type file.
var_dump($data); will show that
if you want to read the data use : fread($data,$buf);
but I think its better with file() function. The example from the docs show a better
method:
?php
$data = implode(, bigfile.txt);
$gzdata =
and if i use
$filename = 'kunden/'.$name.'.png';
$data = fopen($filename, r);
$contents = fread($data, filesize($filename));
fclose($data);
$gzdata = gzencode($data);
$fp = fopen('kunden/zip/'.$name.'.gz', w);
fwrite($fp, $gzdata);
fclose($fp);
it writes in the gz file this

Hello.
I have a unix box which doesn't have anything related to Oracle installed on
it.
Now I have another remote machine: NT w/ Oracle Server 8.
What software/Libraries do i need to install on my linux box in order to
access Oracle database on that NT machine?
Thanks.

Of course it will
$filename = 'kunden/'.$name.'.png';
$data = fopen($filename, r);
$contents = fread($data, filesize($filename));
fclose($data);
// ok so far so good
$gzdata = gzencode($data);
// here is the error, instead of $data use $contents
$fp = fopen('kunden/zip/'.$name.'.gz', w);
ha it works !
thanks !
now just one last question :-))
how can i name my png in the gz file so that it ends with .png ?
i thought this would work
fwrite($fp, $gzdata.'.png');
but it doesn't ! :-(
Of course it will
$filename = 'kunden/'.$name.'.png';
$data = fopen($filename, r);
$contents =
When you use the parser scans the string for variables. When ' is used it is not
parsed. So you know what $variable to put,
concatenate the strings with the variable(s). I think it's a faster method. IMO, yes
it seems ugly, but I want to be faster not so
readable as a novel.

I use the former method when concatenating say a complex SQL query thru a loop or
loops, and me
being the person I am like to keep things standard and consistant so I use the same
method when I
wish to concatenate simpler strings.

I took the variable $db_num and replaced it with a value of 1 as follows:

This writes 'png' at the end of file so the file will be corrupted for every
compressor. If you want to name is foo.bar.gz.png
then:
$fp = fopen('kunden/zip/'.substr($name,0,-4).'.gz'.'.png', w+);
not sure but the substr() have to remove .png from the filename.

Hi Ashley,
Insert records into a table with a primary key that you define,
not an autoincrement field. When 2 people try to insert a record
with the same primary key, one will fail, the other will succeed.
The one that fails will poll the database until the other record
successfully completes

There must be more than one column called datestamp, this is why mysql is
telling you it's ambiguous.
So you need to tell it which table's datestamp column you wish to use.

The different machine has nothing to do with the config, and everything
