Does anybody know?

$champs = array (titre_art = h3 ,nom = bleu, prenom = green,
resume = bold);

foreach($champs as $key = $value) {


echo td class='$value'$row($key))/td;
 }

TIA.

[PHP] getimagesize or loop pblm

[arnaud gonzales]

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.

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] copy after upload pblm (?path?)

[arnaud gonzales]

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 br type : $type br taille : $taille p nom
temporaire : $nom_tmp/p;
if(!strpos($nom, .gif) === FALSE || !(strpos($nom, .jpg) === 
FALSE)){
---$res = copy($fichier,$nom);
if ($res != 0) {
$msg = p File save /p;
}else{
$msg = p saving Error /p;
}
}else{
  $msg = p wrong type /p;
}
?

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

[PHP] php fgets()

[arnaud gonzales]

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.

arnaud G.
