The file:// scheme or the c:\... means that the browser is reading the file directly from the hard disk. The page is not being served by your web server (which I assume you have setup on your local machine). When the browser reads a file from the hard drive, it will display the contents (if it can), parsing out and rendering HTML as it goes. For example, create a file with a php extension with the following contents:- ?php phpinfo(); ? H1This bit is html/H1 Save this in your webroot. Here we have a page that has both html and php in it. If you view this using the file:// or c:\ methods (as used by dreamweaver's preview by default) you will see the H1 rendered and none of the php code, but the php code will not have executed. Compare that with browsing via http://localhost/mytest.php. You'll find that the php has executed and you have the html rendered out below. When testing pages locally the best way to do it is to have a browser open and explicitly browse to http://localhost/dirname/pagename.php /snip Alright, it sounds like a go. Thanks for all the tips. snip I think you'll find that having every page in a separate folder will create an internal link nightmare. I would be inclined to structure your site in a more standard way and use Apache's rewrite module to create the http://site.com/dirname/ style urls you are talking about. You could also use the rewrite module to allow people to request a page with an htm extension, which is translated into, eg: a page with a php extension, a query string passed to a specfic php page, etc. That way you keep search engines and bookmarkers happy but retain your development freedom. It effectively inserts a configurable layer between the browser and the server where you can manage the type and appearance of urls that apply to the site. ISAPI url rewrite filters are available for IIS if that's your server flavour. Hope this helps.

Re: [PHP-DB] Select statement drops 10th digit during table lookup?
Here's how I did it when playing with this...
Table definition:-
CREATE TABLE ip_list (
ip_from double default NULL,
ip_to double default NULL,
country_code char(2) default NULL,
country_name varchar(100) default NULL,
KEY ip_from (ip_from,ip_to,country_code,country_name)
) TYPE=MyISAM;
Basic code to query it (takes a parameter 'ip' as GET paramter):-
?php
/*
IP Lookup script
* prints a country code and name for an ip in the $_GET array
*/
//Vars Constants
define(HOST,myhost);
define(USER,myuser);
define(PASS,mypassword);
define(DB,ips);
define(IP,$_GET[ip]);
// Functions
function dbconnect() {
if (($conn=mysql_pconnect(HOST,USER,PASS))===false) {
die(Couldn't connect to server);
}
if (!mysql_select_db(DB,$conn)) {
die(Couldn't select database);
}
return $conn;
}
function dbclose($conn) {
if (!mysql_close($conn)) {
die(Couldn't close database connection);
}
return true;
}
function dosql($SQL) {
if (($result=mysql_query($SQL))===false) {
die(Couldn't do sql : $SQL);
}
return $result;
}
//Core
$SQL = SELECT COUNTRY_NAME AS cn, COUNTRY_CODE AS cc FROM ips.ip_list WHERE
IP_NUM BETWEEN ip_from AND ip_to;
$conn = dbconnect();
$ip = 127.0.0.1;
$QSQL = str_replace(IP_NUM,sprintf(%u,ip2long(IP)),$SQL);
$result = dosql($QSQL);
$data = mysql_fetch_array($result);
echo ip:.IP.BR;
echo cn:.$data[cn].BR;
echo cc:.$data[cc];
dbclose($conn);
?

Hi buttoz
Here's how I did it ...
function get_script($dbname) {
$cmd = /usr/bin/mysqldump -u._DBUSER. -p._DBPASS. ._MDFLAGS. .$dbname;
$script = `$cmd`;
return $script;
}
_MDFLAGS is a constant which holds the flags you want to pass to mysqldump ... I
commonly use -c and -add-drop-table. _DBUSER and _DBPASS are also constants
containing the username and password mysqldump needs to connect to mysql with (funnily
enough!!). Note there is NO space between the -p flag and the password.

That will give you an indented directory tree listing from the START directory, using
BRK to create the indents. This has no directory limit and will simply work through
the entire tree.

You could build in your search logic pretty easily I think, with an

If you felt that you should point out the register_globals issue, then a simple 'Don't forget register_globals needs to be turned on here and it probably isn't' would suffice. While I am not a php guru (as you seem to be) I have been working with it for a long time commercially and do have some experience, so I am occasionally able to offer pointers on people's questions and offer such advice freely, in the hope that it will help. Lets all be adults, shall we ? You don't get any points for flaming.

Re: [PHP-DB] Entering a Query

thanks for your reply,
What i was after is a way of representing the data, given that you dont know
what columns will be displayed and how many rows etc?
/snip
One way to do it is to load the data into arrays. I generally use mysql_fetch_array()
to access recordsets. This delivers both an Indexed and associative array of values.
You can modify this behaviour with the last argument. Assuming you want to preserve
the keys (which will be the column headings in the sql result), in mysql_fetch_array()
you would use the constant MYSQL_ASSOC. You could do something like this:-
?php
// Assume you have a db connection
if (($result = mysql_query($sql_from_textarea))===0) {
// Drop out gracefully
}
// Check we have some rows
if (mysql_num_rows($result)) {
// We have some rows so load up an array with your recordset
// Start a counter
$counter=0;
// Step thru the recordset
while($data = mysql_fetch_array($result,MYSQL_ASSOC)) {
// loop through the current row, listing keys and values
while (list($k,$v)=each($data)) {
// create a new array member of the form
// $myarray[index][key]=value
$myarray[$counter][$k]=$v;
}
// increment the index counter
$counter++;
}
// Now we have an array which looks like the data so we can // display it
(you could do the keys bit up above as well
// actually)
// get the keys from the first element - safe cos we know
// we have at least one row
$keys = array_keys($myarray[0]);
// Now a standard loop through to first display the keys
// as headings then the data
$html = tabletr;
// Create a row of headings
for ($i=0;$icount($keys);$i++) {
$html .= tdb.$keys[$i]./b/td;
}
// Now loop through the rest of the data
while (list(,$v)=each($myarray)) {
$html .= tr;
// Send keys array pointer back to the start
reset($keys);
while(list(,$b)=each($keys)) {
$html.= td.$v[$b]./td;
}
$html .= /tr;
}
$html .= /table;
echo $html;
} else {
// Drop out gracefully
}
?
Does that all make sense ? Basically, you grab the recordset into an array whose
dimensions you can loop through. Then you grab the keys from an array element to give
you the columns. Then you loop through, using the keys as your guide for when to
change to a new row.
There may well be a more elegant way to do it but this would be where I would start !!
snip
I would only be looking to do 'selects' so how can i ensure that this is the
only type of query run?
/snip
Make sure the user you run the script as, only has select permissions on the db you
are using.
Once again, hope this helps ;-)

Re: [PHP-DB] Sharing variable values among PHP files

// Check if session var is set

if (isset($HTTP_POST_VARS[frm_username])) {
// We have no session var and a form var
// waiting for us
$HTTP_SESSION_VARS[ses_username]=$HTTP_POST_VARS[frm_username];
}
}
// Now $HTTP_SESSION_VARS[ses_username] exists and contains
// the username
snip
session_register(ses_username);
}
// Are we getting a form var thru ? if so pop it into the session var
/snip
You can shorten $HTTP_SESSION_VARS to $_SESSION if PHP version 4.1.0.

You should try using one of mysql_fetch_array() / mysql_fetch_row() to step through
the recordset. Something along the lines of
?php
while ($data = mysql_fetch_array($req)) {
// handling code for each row here using references like this
$id = $data[id];
$titre = $data[titre];
echo trtd$id/tdtd$titre/td/tr\n;
// \n above to keep the html source reasonably tidy

I want that my script show the content of the rows corresponding to my

So the variable is moving well but when the scirpt is running and go to

It did !! I had tried a direct pipe, but had neglected the all important semi-colon

Is this reasonably efficient on your production server ? Do you have any problems
with it ?
Also, how are you dealing with growing table sizes ? Do you summarise out data to sub
tables ? Or do you limit the date range and periodically dump stuff that is out of
range ?
Part of the reason for using Perl / PHP, etc was to allow the log data to be filtered
and sorted prior to inserting to the db. This would then allow automatic summarising
so you could maintian host tables, request tables, etc and limit the size of the main
transfer log tables.
My approach to the queries thus far has been to keep different 'reports' (which
essentially narrow down to individual SQL queries) in a db. A user picks a report,
the SQL is selected and run and the data is then displayed (also playing with JPGraph
to produce some nice charts).
Works quite well and means that adding a new 'report' is simply a matter of adding a
row in the reports table.

On 27 Mar,2003 at 13:46 Dave Carrera wrote: Hi all Hi Dave I have a database holding file locations of images on my system. This works fine and shows them fine on a webpage. I was wondering if it is possible to generate and automatic thumbnail from the original image (all jpegs) so that I can click the thumbnail to see the larger image. I know I can make a small image and a large images and store and retrieve those but I was just wondering if it is possible to do auto thumbnails from the array of images. You could write yourself a little script to generate a thumbnail on the fly ... use an img tag like img src='thumbnailscript.php?image=thisimage.jpg' You could simply cycle through your array and let the thumbnail script create the image for you each time. Have to say, not very efficient ... you'd be far better off either doing an upload form that creates your thumbnails at upload or writing a little PHP daemon that sits on the server and chucks back the image data when queried... I would resize on upload...still automatic and only do it once rather than every page load...you'll bring your server to its knees if you have a large site with lots of hits (or even a small site with lots of hits).

[PHP-DB] PHP for apache logging to mysql
Hi folks
Ronan here. Just joined the list. I do PHP / MYSQL / GD / HTML / JavaScript / Flash
stuff, building db driven sites, content management systems, etc. I also use PHP as a
scripting langauge on my servers - its generally great.
However I have a little problem which someone might have come across or be able to
shed some light on. I want to pipe logs directly from apache into mysql. At the
moment I can do this using a perl script that does this sort of thing:-
script
#!/usr/bin/perl
[ DB CONNECTIONS etc ]
while (STDIN) {
[ DO DB INSERTS HERE ]
}
[ DB OBJ CLOSURE etc ]
/script
I'm doing this in PHP:-
script
#!/usr/bin/php -q
?php
$fp = fopen(/dev/stdin,r);
$inputfp = fopen(./input.txt,a);
function write_input($input, $inputfp) {
[ DB INSERTS HERE ]
}
$input = fread($fp,4096); // 4096 arbitrary value for testing
write_input($input,$inputfp);
fclose($inputfp);
fclose($fp);
?
/script
Works great if I manually pipe from ls or something
(ie: ls ~/ | phplog.php) but nothing happens when piping from apache. I reckon that
the problem lies in the file pointer reading - perl seems to keep the pointer (ie:
pipe) open while php seems to close the pipe after each fread().
Any clues ???
Cheers
