RE: [PHP-DB] Shrinking gifs.
Thank you Martin
I install new gd, reconfigure php and now is running OK.
But, it was a mass to realize that shortening gifs results to loss
transparency(!).
So I turn them all to jpegs and use the ImageCreateFromJPG instead.
My code looks like this:
?
$ph='photos/'.$photo;
$imgReal = imagecreatefromjpeg($ph);
$x = ImagesX($imgReal);
$y = ImagesY($imgReal);
$newX=$x*0.50;
$newY=$y*0.50;
$img = ImageCreate($newX,$newY);
ImageCopyResized($img, $imgReal, 0, 0, 0, 0, $newX, $newY, $x,
$y);
ImageJPEG($img);
header(Content-Type: {$img_type});
echo $img;
?

Hello list
I'd like to make a thumbnaile list using some gifs.
I use the following code but I got error (Call to undefined function:
imagecreatefromgif() ).
Does anybody knows what's wrong?
[snip]
RH-9 Linux
Apache httpd-2.0.40-21.11
PHP Version 4.3.11
gd-1.8.4-11
gif support was removed from gd in 1.6*. It was re-added in 2.0.28.
This is all due to the Unisys patent on the LZW compression that gifs
use.
short answer - you just don't have support for making gifs, it was a
licensing issue at the time the software you're using was
released/packaged. Upgrade gd.
* funny, since gd stood for 'gif draw' originally.

[PHP-DB] Re: splitting CSV rows into multiple SQL inserts?
I wanted to clarify my question from yesterday, as re-reading it, it
sounds quite confusing.
I have a CVS file that has order header *and* line item info on each line,
like:
1110,6/20/2005,Jan Doe,123 Main St,,1,Book
1116,6/22/2005,Jim Smith,44 Here St,19191980,1,CD
1116,6/22/2005,Jim Smith,44 Here St,77736222,1,Tape
The above is actually two orders - one with one line item, and the 2nd
with two line items. I need to insert data from those lines into two
tables:
insert into order_header (o_num, date, name, addr)
values ('1110','6/20/2005','Jan Doe','123 Main St'),
('1116','6/22/2005','Jim Smith','44 Here St');
insert into line_items (o_num, item_num, quan, desc, line_order)
values ('1110','','1','Book','1'),
('1116','19191980','1','CD','1'),
('1116','77736222','1','Tape','2');
Note the line_order field - it needs to increment per order for each line
item added to the line_items table. To complicate matters a bit, I'm
actually massaging the data before inserting [eg: splitting the name field
from the CSV into two fields for the mysql db, formatting the date field
for mysql, etc].
I'm currently doing this process via a form where a user uploads the CVS
file [created with Excel, complete with the first row being made up the
Excel table's header].
I currently do something like this:
$fp = fopen(/tmp/.$txt_file, r);
while ($line = fgets($fp,1024))
{
$i++
if ($i 1) { // skip excel header row
list ($o_num, $date, $name, $addr, $item_num, $quan, $desc) =
csv_explode($line);
// i can now print the vars, but i get duplicate header records when
// there are multiple line items for a particular order. also, i
// need to generate the line_order field for insertion into the
// line_items table
}
}
If I try and do any processing up where my comments are, well, the
comments tell you what happen. I know I am reading this file line by line,
so I can't compare order numbers [o_num] to group multiple line item
orders together. So how do I go about doing that? Read the entire CSV into
an array? How can that help? Any tips would be most appreciated!
Thanks!

function csv_explode($str, $delim = ',', $qual = \)
{
$len = strlen($str);
$inside = false;

for ($i = 0; $i $len; ++$i) {

[PHP-DB] mysql_connect() with a multi-file format
I'm new to PHP, due to having been all hard-nosed and obtuse about using Perl/CGI. I've been looking for a good way to pick up php tricks and what-nots, so I joined the list. That said, I have an immediate question. I have a multi-file script: main.php requires_once config.php, and so on. I'd like to have a data.php file that handles function wrappers for database and also establishes a connection to the db. I read in the php.net manual that the connection closes automatically when the script exits. Does this mean I can't open a db connection in one file and pass the link around from function to function? ie: require_once 'data.php'; // data.php contains a mysql_connect() // after this line, is my link closed? require_once 'blah.php' ; OR: require_once 'data.php'; // with wrapper data_connection() $save_this_link = data_connection() ; // will this work? some_function( $save_this_link ) ; //etc. -- Douglas Hernandez (612) 229-9684 -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

No, the script you include becomes part of the main script calling the inclusion, therefore the connection stays open 'til you explicitly close it, or your main script exits. cheers -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
