[PHP-DB] Tree structures...
What's the best way to deal with tree structures? Use the following setup in a database as an example: ID | Parent | Description 1 || Colours 2 |1 | Red 3 || Hello 4 |1 | Green 5 | 4 | Light 6 | 4 | Dark This should be represented as: 1. Colours 4. +--Green 6. +--Dark 5. +--Light 2. +--Red 3. Hello (ie, in tree structure and ordered alphabetically by 'descriptiu What's the best way to select the data and render it in HTML? I thought about going thru each element (of the whole table) at a time, and making an array, dynamically adding bits of the tree together until the whole tree has been grown ... but it seems a little bit complicated and slow ... is there anything that could be done [database]server-side which might help me? Or do other people have code snippets, ideas or anything which might help me??

[PHP-DB] file name extentions
Hi there, Currently my ISP has PHP 3 installed and to run php scripts I have to save the file as name.php3 I expect to install my own server and php4 in the foreseeable future - how can I save the files as .php so that they are upwardly compatible? I have tired using the filenmae file.php but the server will not execute the file. Any suggestions?

Re: [PHP-DB] How to sort numerically ?
Dear Sunil,
First of all make an array of you are reading from file.
Like that:
?
$sel = "Selcect fild1,fild2 from myfile";
$res= mysql_query($sel);
while ($row=mysql_fetch_row($res))
{
$my_array[$row[0]] = $row[1];
}
// tem:
asort($my_array);
for(reset($my_array); $ind=key($my_array); next($my_array))
{
print ("$ind : $my_array[$ind] br");
}
?

Re: [PHP-DB] Tree structures...
Joe Celko wrote a book called "SQL for Smarties" that has about 20 pages devoted to representation of trees in SQL. I believe he also has a website. His quick take on representing trees in SQL is that hierarchical databases do this far better and a RECURSIVE UNION funtion is needed to do this in SQL. Which we don't have -- maybe SLQ3? But, cribbing freely from his book, try this ... Lets call the table "things" select D1.Description, "Descrip", P2.parent from things as D1, things as P1, things as P2 where D1.Parent = P1.ID and P1.Parent = P2.ID I don't see how this handles the null values, but I hope it can get you started. I'll cheerfully hand this on to persons more expert in SQL than myself. HOw you display it, once you have the values fetched is another exercise. The book is worth getting.

[PHP-DB] mysql grant problem?
When we use grant as following: GRANT select(col_name_1) on db_name_1.tbl_name_1 to peter identified by "peter"; Then peter can only select the field of col_name_1 on the tbl_name_1 of db_name_1. However, when peter issue the query: DESC tbl_name_1; he can see all the structure of that table. This makes that peter does not know which column he can use. Does any body know how to make peter only can see the column which he has right to use it when he issue DESC tbl_name_1. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

[PHP-DB] uploading files.
K, I am using a script i found at hotscripts.com
I need it to upload an image to server.
I think that my issue is that i need to use the stripslashes(); somewhere, but i don't
know where
anyways here tis:
?
function do_upload($filename,$newname) {
$file = basename($filename);
$tmp_upload_path = "c:/program files/apache group/apache/htdocs";
$new_file_name = "c:/program files/apache group/apache/htdocs".$newname;
$file = stripslashes($file);
$tmp_upload_path = stripslashes($tmp_upload_path);
$new_file_name = stripslashes($new_file_name);
if (!copy($tmp_upload_path.$file, $new_file_name)) echo "failed to copy filebr\n";
return;
}
?
and later i calll the function:
? do_upload($userfile,$newname); ?
here the error i receive:
Warning: Unable to open 'c:/program files/apache group/apache/htdocsphp2' for reading:
No such file or directory in c:\program files\apache
group\apache\htdocs\uploads\2\upload_go.php on line 9
and script returns this
upload tmp file: \\php2
There is an article at phpbuilder called file uploading made easy
http://phpbuilder.com/columns/bealers2904.php3
i am having the same issues with this script and though i found an answer to the

script that there is an unset variable... It looks set to me :)

Re: [PHP-DB] connection id
Use persistent connections it's a matter of performance of your script. When you use persistent connections the next call to mysql_pconnect will catch a opened connection if available. The mysql_connect command always open a new connection which slower than get an opened one. Anyway you can't use the connection_id in other page. May be using PHP4 Sessions. HTH.

[PHP-DB] RE: [PHP] connection id
TIA, What you described is not possible. When you create that connection to the mysql server, that connection dies when the script ends... As far as persistent connections go, you will always call the code to create the connection, but that connection lives on in that apache child process until that child process dies. So for example, apache spawns a child process to handle a request and it executes your PHP script with the persistent connection code (mysql_pconnect) and then after you script exits, that child process keeps the conection to mysql open. Any PHP script afterwards that uses the same connection information (host, username, password) with the mysql_pconnect() call; apache checks for an existing persistent connection (that was created with the first PHP script execution) so it returns that connection id. If you use the standard mysql_connect call the apache child will drop the connection when the script ends.

[PHP-DB] SQL Select?

Is there any way of using a string in an SQL query instead of using the

$result=mysql_query("SELECT * FROM $tablename",$db);

Re: [PHP-DB] SQL Select?
Grant,
$link_id = mysql_connect($host, $usr, $pass) or die (mysql_error());
mysql_select_db($database, $link_id);
$sql="select fields from $table where criteria = $value";
$result = mysql_query($sql, $link_id) or die ("no results"); //return result
set to php
you still need to do something with $result.
also, if you use mysql_fetch_array instead of mysql_query, you get a
row-matched array.
Best regards,
Andrew

"SELECT * FROM $tablename" should be sufficient to permit PHP variable
expansion. MySQL will also require a string value to be quoted, so if
$tablename is a string, change the query to "SELECT * FROM '$tablename'".
AFAIK, the missing inner quotes would not cause a PHP parse error, only a
MySQL error. So you may want to look for something else in your code that
could be causing the parse error.
