The FROM ISP doesn't allow it. What about the TO ISP? If you can get them to allow access from the old server: $Con1 = mysql_connect( 'oldhost', 'olduser', 'oldpassword' ); mysql_select_db( 'olddbname', $Con1 ); $Con2 = mysql_connect( 'newhost', 'newuser', 'newpassword' ); mysql_select_db( 'newdbname', $Con2 ); $R1 = mysql_query( SELECT * FROM tablename, $Con1 ); while( $Data = mysql_fetch_array( $R1 ); mysql_query( INSERT INTO tablename ~data~, $Con2 ); } Of course you will need to translate '~data~' into a valid SET or VALUES() block for each table, but this may allow you to get your data out of the old ISP's server without their help.

I'm using PHP applications and MySQL Database, WindowsNT4 IIS You've got several options and it all depends on how synchronised you need/want them to be. If you need up-to-the-minute sync then the mysql replication feature is the only way to go. Other methods are: Using mysqldump: 1) Dump from local mysql straight to remote mysql: mysqldump --opt name_of_database | mysql --compress -h remote.mysql.host name_of_database 2) Dump from local mysql and compress to file: mysqldump --opt name_of_db | gzip name_of_db.gz Then ftp to remote, decompress and import. 3) Install phpMyAdmin on both machines. -- Jason Wong - Gremlins Associates - www.gremlins.com.hk Open Source Software Systems Integrators * Web Design Hosting * Internet Intranet Applications Development * /* BARBARA STANWYCK makes me nervous!! */ -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DB] Advice to PHP beginners
Just some advice... You should use a consistent programming style,
especially with PHP. You can read some guys advice here.
http://www.phpbuilder.com/columns/tim20010101.php3?page=1
Some of the advantages of having a consistent style, is when you are
looking for bugs. If you look over your code and see something unusual,
then you can target that area to see if it is the culprit. If you don't
have a consistent style, then sometimes that can cause serious
heartache, as everything will look unusual.
A few issues that trip up most people when beginning to use PHP, is the
syntax errors. Usually these arise from quote issues, to semi-colon and
brace issues. A lot of this trouble can be avoided (or easily debugged)
by simply using tabs to your advantage. Consider the following:
?php if ($condition){ echo correct;} else {
echo 'what';
if (!$condition2){
include 'thing.php';
while (!$dead)
{ if ($jam!= $yes){ $dead = true;
} else{
for ($i=0;$i100;$i++)
{ $thing = processSomething('something', something2);
$string = 'something'.$here.too;
}
?
Technically I *think* this would be syntactically correct, but if I was
looking for a bug, I would be shot in the foot. A better way to write
this would be the following:
?php
if ($condition){
echo correct;
} else {
echo what;
if (!$condition2){
include ('thing.php');
while (!$dead){
if ($jam != $yes){
$dead = true;
} else {
for ($i=0;$i100;$i++){
$thing = processSomething(something,
something2);
$string = something $here too;
}
}
}
}
}
?
So its a couple more lines, but if I came back to that script a month or
two months later trying to fix something, or add a new feature, it would
be easy. Couple that style with comments and you're on fire!!!
Hope this helps for someone out there...

[PHP-DB] Re: OT - [PHP-DB] Advice to PHP beginners
did the tabs get stripped in your mail, or is there a reason the code
couldn't be written like the following?
i'm curious, since this is the way i do 90% of my code - makes it easy to
see what's going on... but i dunno about performance or parsing impact
(never gave it much thought until now)...?
newbily yours...
?php
if ($condition){
echo correct;
} else {
echo what;
if (!$condition2){
include ('thing.php');
while (!$dead){
if ($jam != $yes){
$dead = true;
} else {
for ($i=0;$i100;$i++){
$thing = processSomething(something, something2);
$string = something $here too;
}
}
}
}
}

RE: [PHP-DB] Advice On Building Dynamic MySQL Queries
I actually created an array of different conditions like:
$ConditionsArray = array("Var1 500","Var2 1800","ID=43");
and then:
$Conditions = join(" AND ", $ConditionsArray);
This constructs:
$Conditions = "Var1 500 AND Var2 1800 AND ID=43";
shrug Worked well for me.

Subject: [PHP-DB] Advice On Building Dynamic MySQL Queries
I am building a query from a search form. This is the code I have now:
if (!empty($whereclause))
{
$whereclause=urldecode($whereclause);
$whereclause=stripslashes($whereclause);
}
extract($HTTP_POST_VARS);
if (!empty($Price))
{
if(empty($whereclause))
{
$whereclause.="Price$Price";
}
else
{
$whereclause.=" AND 'Price $Price";
}
}
if (!empty($Area))
{
if(empty($whereclause))
{
$whereclause.="Area LIKE '$Area'";
}
else
{
$whereclause.=" AND Area LIKE '$Area'";
}
}
if (!empty($MLS_Number))
{
if(empty($whereclause))
{
$whereclause.="MLS_Number LIKE
'$MLS_Number'";
}
else
{
$whereclause.=" AND MLS_Number LIKE
'$MLS_Number'";
}
}
if (!empty($File_Number))
{
if(empty($whereclause))
{
$whereclause.="File_Number LIKE
'$File_Number'";
}
else
{
$whereclause.=" AND File_Number LIKE
'$File_Number'";
}
}
if (!empty($Description))
{
if(empty($whereclause))
{
$whereclause.="Description LIKE
'%$Description%'";
}
else
{
$whereclause.=" AND Description LIKE
'%$Description%'";
}
}
$query="SELECT
lid,Price,Address,Area,Description,File_Number,Realtor_First_name FROM
listings LEFT JOIN areas ON (listings.aid=areas.aid) LEFT JOIN realtors ON
(listings.rid1=realtors.rid) LEFT JOIN prop_types ON
(listings.ptid=prop_types.ptid) LEFT JOIN prop_styles ON

#echo "$querybr";
if(empty($whereclause))
{
echo"centerh2You Did Not Specify Anything To Search

a href=\"javascript:history.back()\"Back/a/center";
}
else
{
$results=$CONNECTION-Execute("$query") or
DIE($CONNECTION-ErrorMsg());
$results__numRows=0;
$results__totalRows=$results-RecordCount();
echo $results-Fields("aid");
echo "$querybrbr";
while ($results__numRows$results__totalRows)
{
#SNIP Display stuff
$results__numRows++;
$results-MoveNext();
}
$results-Close();
}
It Just became apparent that I am going to need to add a whole bunch more
search criteria.. Does anyone have any advice/suggestions for getting rid of
all those if statements?

Re: [PHP-DB] Advice On Building Dynamic MySQL Queries
Thanks for the replies :)
Victor's suggestion put me on the right track. (I still have trouble with
language constructs)
Heres what I have now.. All I need to do is name my form fields with the
same name as the column names from the mysql table, and presto! now I can
just add/remove from the search form without changing the code. (I hope.. It
has worked so far).
while (list ($key, $val) = each ($HTTP_POST_VARS))
{
if (!is_int($key) $key!="Submit" $key!="submit"
$key!="offset")
{
if (!empty($val))
{
if (!empty($whereclause))
{
if($key=="Price")
{
$whereclause.=" AND Price$val";
}else{
$whereclause.=" AND $key='$val'";
}
}
else
{
if($key=="Price")
{
$whereclause.=" Price$val";
}else{
$whereclause.=" $key='$val'";
}
}
}
}
}

what about using a foreach statement and going through all the
variables you need like this ?
$myvars = array('Price', 'Stuff', 'Thing');
foreach ($myvars as $varname) {
if (!empty($$varname)) {
// do funky stuff here
}
}

Re: [PHP-DB] Advice On Building Dynamic MySQL Queries
My solution was almost as elegent...
$query="select * from customers";
$queryand=false;
if(!empty($f_Account)) {
$query.=" WHERE upper(P.Account) like upper('$f_Account')";
$queryand=true;
}
if(!empty($f_First_Name)) {
$query.=($queryand?" AND ":" WHERE ")."upper(p.First_Name) like
upper('$f_First_Name')";
$queryand=true;
}
...
For searchs, case doesn't matter (in my example), but you do need to index
your table accordingly for best results.
Also note upper() is the oracle uppercase function. I believe the uppercase
function varies from one RDBMS to another.

or something like this ;-)
