[PHP] How to disable cache, image headers?
Hi, I'm creating images on the fly. They are called as follows: Where mypicture.php creates a png file, modified each time. Everything was fine with IE, but then I tested it with Netscape and it didn't work anymore. An old version of the picture was shown on the screen. I understand NS is using a homemade cache system, so I tried the usual "Pragma: no-cache" header, but it didn't seem to work either... Any idea how I can force NS to update the image? Thanks, Arnaud PS: I don't want to use a trick like adding a random number at the end of the picture's url, it's for a professional application... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] GD : Black background with imagecreatetruecolor
Hi everyone, I'd like to use "imagecreatetruecolor" function in order to "cut and paste" JPG files on a white background. It seems not to work correctly. Here is my test scripts : This one works perfectly : I obtain a white image but using GD 2.x, the "imagecopy" function fails. This other script doesn't work : I'm getting a black image. My configuration is PHP 4.2.3 with gd2 running on Windows XP (I've also tested it on my web provider machine - Linux with PHP 4.2.2) Any help would be great. Thanks in advance Arnaud -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

It could take a while. Depends how fast your server's disk sub-system is.
Going to disk to stat and open an image and then parse through the initial
headers to get the sizing data can take some time. I'd suggest caching
this data somewhere if you are going to need it on every request.

[PHP] getimagesize or loop pblm
Hi all,
Does anybody can tell me why i have this error :"Fatal error: Maximum
execution time of 5 seconds exceeded in photos2.php on line 28"
whith this
$tab_img = array();
$tab_img_size = array();
for($i=0;$i=56;$i++){
$tab_img[$i] =
"images/tof/real_size/techp02_".$i.".jpg";
$tab_img_size = array(
/* line 28 */ $i => getimagesize($tab_img[$i]));
}
Is the getimagesize function too long for making it 56 times??
What do u think ?
In fact i want to get all the image size to make a popup link on the
thumnail at the real size of the image.Because images don't have the same
size and i want to have a clean window whith the popup.
I've ever tried this before :
$tab_img = array();
$tab_img_size = array();
for($i=0;$i=56;$i++){
$tab_img[$i] =
"images/tof/real_size/techp02_".$i.".jpg";
$tab_img_size[$i] = getimagesize($tab_img[$i]);
}
Hope you understand.
TIA.

[PHP] copy after upload pblm (?path?)
Hi all,
I' m trying to copy an uploaded file:
if(!empty($fichier)) {
$nom = $HTTP_POST_FILES["fichier"]["name"];
$type = $HTTP_POST_FILES["fichier"]["type"];
$taille = $HTTP_POST_FILES["fichier"]["size"];
$nom_tmp = $HTTP_POST_FILES["fichier"]["tmp_name"];
echo "nom : $nom type : $type taille : $taille nom
temporaire : $nom_tmp;
if(!strpos($nom, .gif") === FALSE || !(strpos($nom, ".jpg") ===
FALSE)){
--->$res = copy($fichier,$nom);
if ($res != 0) {
$msg = " File save ";
}else{
$msg = " saving Error ";
}
}else{
$msg = " wrong type ";
}
?>
and i get the error "Warning: open_basedir restriction in effect. File is in
wrong directory in d:\tsunami\zeg\9\exo4upload.php on line 5"
so is there any wrong path for $res = copy($fichier,$nom);

[PHP] php fgets()
Hi,
I'm newbie in php and i would like to clearly understand how can i use:
LENGTH in string fgets ( int fp [, int length])
"Returns a string of up to length - 1 bytes read from the file pointed to by
fp. Reading ends when length - 1 bytes have been read, on a newline (which
is included in the return value), or on EOF (whichever comes first). If no
length is specified, the length defaults to 1k, or 1024 bytes."
-Can i have an example of the differents way for reading file with fgets
according to thedifferentes values of "length "?
-why '4096' is used as length for reading a file line by line ?
$fd = fopen ("/tmp/inputfile.txt", "r");
while (!feof ($fd)) {
$buffer = fgets($fd, 4096);
echo $buffer;
}
fclose ($fd);
Is this any max for one line??
TIA.
