RE: [PHP-DB] MySQL/PHP dropping characters
-Original Message- From: Micah Stevens [mailto:[EMAIL PROTECTED]] Sent: 23 September 2002 18:09 I've been running into a strange problem on my server with scripts that take form input and reformat it into SQL. It only happens with statements that insert or update data, the first four characters of the POST variables starting at the fourth variable passed are dropped. There are several bug reports at http://bugs.php.net for this -- basically, it seems to be related to transparent multi-byte string encoding (or something like that). If you don't need that support, you should turn it off -- search the bug database for the appropriate bugs, which will give you more information than my brain can! Cheers!

RE: [PHP-DB] getting mysql_fetch_row into array
-Original Message- From: LSC Exhibits Department [mailto:[EMAIL PROTECTED]] Sent: 23 September 2002 18:17 Going through brain-lock here. From this query Select count(deptid) from maintenance group by deptid ,I get 11 rows. What I need to do is get an array like $a=array(315,11,43,67,415,32,25,63,93,46,76) from this query, so that $a[0]=315 $a[1]=11 $a[2]=43 and so on. The best I can get is ; $a[0][0]=315 $a[0][1]=11 $a[0][2]=43 and so on. Does anyone have any ideas??? Won't that do? If you don't want to refer to it using the additional first subscript every time, just create a reference to it: $b = $a[0]; then $b[$x] is the same as $a[0][$x]. Cheers!

You can't carry a connection resource from one page to another -- you have to script an OCILogon (or OCIPLogon) in every page that needs to access your database. (This is true not just for Oracle -- all the databases supported in PHP that I've looked at work the same way.) Cheers!

Re: [PHP-DB] BLOB retrieval
Go to www.php.net and type in the name of your database (mysql, postgres, oracle, mssql) in the search box. That will give you a list of all the functions available. Getting a blob is generally the same as getting any other data type. Here's the paradigm: 1. connect to the database 2. execute SQL statement 3. parse/display results WIth MySQL, this is done with the following functions: // 1. connect to the database mysql_connect( host, user, pass ); mysql_select_db( db_name ); // 2. execute SQL statement $result = mysql_query( sql ); // 3. parse/display results $array = mysql_fetch_array( results of above query ); Here are a couple pretty decent tutorials on using PHP and MySQL that will probably get you started: http://uug.clubs.byu.edu/articles.php?show_article=11 and http://uug.clubs.byu.edu/articles.php?show_article=53 But, of course, PHP.net is the ultimate source of excellent documentation on php. You should rarely need to go anywhere else (including google) to get most php info. Good luck. Let us know how it goes! --Dave chekmate (remove) wrote: Hi everyone, I am new to php.

[PHP-DB] ODBC?
Hi there everyone, I have always used MySQL with PHP without any problems using the standard MySQL connection functionality. Is it possible to connect to a MySQL DB via ODBC? If so, what would the PHP Connection string be? I am curious as my email server allows you to use external databases for users accounts and I figure this way I could write a PHP script to control users email accounts.

You have to store the login information in a session var or in the database.

First make sure you have installed the MyODBC Driver Then make a odbc DSN to the MySQL database.

[PHP-DB] Re: password function
When using aggregate functions in sql, it is good to name that expression
using the AS keyword.
Try this:
$result = mysql_query(select password(.$_POST['password'].) AS pword);
while ($p = mysql_fetch_array($result, MYSQL_ASSOC)){
$pswrd=$p['pword'];
}
Also, like David said, you should also have exception handlers (need not be
advanced). If you're like me and hate having to type too much, chuck your db
stuff in a function. A very simple one would be doing this (this is not
tested, by the way):
function query($sql){
return mysql_query($sql) or die(Error: . mysql_error());
}
Then to call it, simply
$sql = select password(.$_POST['password'].) AS pword;
$result = query($sql);

[PHP-DB] Mysql vs postgresql
Hi peoples, The company I'm about to partner with for hosting my websites is using postgresql for their database server. I currently use mysql for all of mine. What I'm trying to find out is peoples experiences using postgresql, any plusses or minusses, is it worth using these guys or finding another company that will use mysql instead? Most of the sites are being rewritten at the moment anyway so changing the code isn't really a factor for me.

Unfortunately this concatates the numbers instead of summing them I need
it to sum them.even if I type cast it to int it still concatates them.
what I need is from the array:
array(0,23,2,15,1,14,1,43,22)
a new array having:
array(0,23,23,25,25,40,40,41,41,55,55,98,98,120)
think of angle and ) being the beginning 23 being the end then 23 being
the begging of an angle haveing 2 degress so I need it to go to 25 and
so forth. hope this explains it better.
Getting back to those that helped. I ende up splitting the arrays one
for start and one for end. I then added 0 to start and subtracted the
last from start. here is the code I ended up with:
$a=array();
while($d=mysql_fetch_array($start_angle_query))
{
$a[]=$d[0];
}
//copies mysql_fetch_array into an array
$b=array();
$b =$a; // make two arrays one for start of angle 2nd for end of angle
$degree_adjuster=360/array_sum($b); //constant for circle
array_unshift($a,0 ); // add 0 for start angle
$start_angle=array(); // new array to hold values for start vector
$end_angle=array(); //new array to hold values for end vector
array_pop($a); //trim one array for start so numbers don't end on 360
while($a) //iterate till array is empty
{
array_push($start_angle,(end($start_angle)+ $a[0]));
/*enter numbers in array $start_angle adding the last number in array
and adding the
first number from modified original array*/
array_shift($a);//delete first value of array
}
while($b)
{
array_push($end_angle,(end($end_angle)+$b[0]));
array_shift($b);
}
