Re: [PHP] Generating thumbnails of JPEG/GIF images
I wrote a small function like the following to create my won thumbnails.
function make_tumb_nail($url){
$size=GetImageSize("image/$url");
$ht=$size[1];
$wd=$size[0];
if($ht>$wd){
$h=$ht;
for($i=1.01;;){
if($h<121){
break;
}
$h=$ht/$i;
$w=$wd/$i;
$i=$i+0.01;
}
} else {
$w=$wd;
for($i=1.01;;){
if($w<91){
break;
}
$h=$ht/$i;
$w=$wd/$i;
$i=$i+0.01;
}
}
$wd=floor(round($w));
$ht=floor(round($h));
$returnstring="width=$wd height=$ht border=0";
return $returnstring;
}
This function returns the thumbnail width and height as string and use
it along with the original string.

Hope this helps.

[PHP] very basic question, needs direction!
Hello, I am using PHP as my main language in my websites. I am planning to set up my own server to host all my domains. Is there a place, where I can see, how do I set up a server with PHP as the main language and what are the hardware/software requirements for this? All I need is just a url or if anybody already did this, please let me know.

If you declare the fields as NOT NULL in mysql table, during insert, if you are nor insertint the field, it will default to 0 (for numbers) and 'blank' (for text fields).

Re: [PHP] Qoute problem
My approach towards this problem was to parse the data before inserting and before displaying. Before inserting the data entered by user, do something like str_replace($comments, "'","~") and do the same thing for " do a different character like | and then insert it into database. Do the reverse before displaying the data, it should fix your problem.. Tanya Brethour wrote: > Hi! I was hoping that someone could help me out.

Re: [PHP] @ Scope
My understanding is, it simple supress the any messages generated from

Re: [PHP] mysql +php+ array
Hi Ramiro,
Your code looks ok, why don't you try the following and tell me is
working or not
$arr_aantal = explode (",", $aantal);
$arr_str_men = explode (",", $str_men);
$arr_recht = explode (",", $recht);
$arr_rechtverstek = explode (",", $rechtverstek);
$arr_verstekgelijk = explode (",", $verstekgelijk);
$arr_verstekongelijk = explode (",", $verstekongelijk);
rows = count($arr_aantal);
for($b=0; $b<$rows; $b++):
$sql = "INSERT INTO $table_name SET aantal='". trim($arr_aantal[$b]) ."',str_men='"
. trim($arr_str_men[$b]) ."',recht ='"
.. trim($arr_recht[$b]) ."',rechtverstek='" . trim($arr_rechtverstek[$b])
.."',verstekgelijk='" . trim($arr_verstekgelijk[$b]) ."',verstekongelijk='" .
trim($arr_verstekongelijk [$b]) . "', soorten=
'$bewaar'";
mysql_query ($sql)
or die ("cannot execute update query");
}
only change I made was to use the count from explode.

Re: [PHP] Time in php problem....
I think you can do all of these using the session. In your log on script, after validating his uid and pwd, insert a row with current timestamp and his id. Either during log off or session close insert another row with uid and current time stamp. (This part I never done) Rest is to manipulate the values the log table information. (may be develop a admin screen, which manipulates the log table) Hope this helps.

$id_link = @mysql_connect('localhost',$uid,$pwd);
$result=@mysql_db_query($db,$id_link,"show tables");
