PHP - Opinion: Multiple Websites Same Data: Individual Db's Or Single Db?
Hello!
I have five websites on a single server, and each website uses the same geographic data, for instance US zip codes and city/state latitudes and longitudes. Each website uses it's own copy of these "large" tables.
I would like to avoid having to maintain the same data in 5 databases, but I am more concerned with database performance, e.g., the speed at which the data is retrieved for each website.
Question: Should I set up a new separate database that contains the shared tables for all websites and allow each website to connect to this new database for shared data? Or is it better for each website have it's own copy of the duplicate tables?
Thanks for any info!
Cheers
Similar TutorialsHi.
I have a product database w/ tables each for product series, model, sub-model and optionals. One item in each of these makes up one product. So Series K, Model 7, sub-model 2, optional 3 will be a product called K 7/2-3 .The permutations and combinations of these are all possible products.
In the same db, I have a quotations table. Each quotation has a unique id / record. A quotation can include any number of products : it can have K 7/2-3, KA 561/1-2 , FPN 311/2-1 or it can only have KA 561/1-2 etc.
Now I am stuck. Don't know how to
a. structure the quotations table
b. create a MySQL select so that one statement can make multiple selections . I thought of using a checkbox but that doesn't work either since the series/model/sub model/optionals must chosen sequentially.
Any ideas I can follow thru ?
Many thanks

I have stored supplier information in a table and same form user will select multiple products for that supplier and that will be stored in a seperate table against that supplier id. Now when i would like to display all supplier information with muliple products in a single line. Now all the information will be displayed as many time as the products are. How to display all the products in a same line.
Now my display is like this
if(isset($_POST['submit']) && ($_POST['vendor']!='') && ($_POST['item']!='')) { $sql="SELECT supplier.id AS sid, supplier.name AS SNAME, supplier.category, supplier.website, supplier.email, supplier.phone, supplier.vat, supplier.pan, supplier_location.id, supplier_location.supplier_id, supplier_location.location, supplier_products.id, supplier_products.supplier_id, supplier_products.product_id, location.loc_id, location.name AS locname, products.product_id, products.name AS pname FROM supplier INNER JOIN supplier_location ON supplier.id = supplier_location.supplier_id INNER JOIN supplier_products ON supplier.id=supplier_products.supplier_id INNER JOIN location ON supplier_location.location = location.loc_id INNER JOIN products ON supplier_products.product_id=products.product_id WHERE supplier.id=".$sup." AND supplier_products.product_id=".$product; $sql1 = mysql_query($sql) or die(mysql_error()); <table> <thead><tr> <th>Vendor ID</th> <th>Vendor</th> <th>Category</th> <th>Website</th> <th>Email</th> <th>Phone</th> <th>Products</th> <th>Locations</th> <th>VAT</th> <th>PAN</th> </tr> </thead> <tbody> <tr> <?php while($row = mysql_fetch_array($sql1)) { ?> <td><?php echo $row['sid'] ?></td> <td><?php echo $row['SNAME'] ?></td> <td><?php echo $row['category'] ?></td> <td><?php echo $row['website'] ?></td> <td><?php echo $row['email'] ?></td> <td><?php echo $row['phone'] ?></td> <td><?php echo $row['iname']; ?></td> <td><?php echo $row['locname']; ?></td> <td><?php echo $row['vat'] ?></td> <td><?php echo $row['pan'] ?></td> </tr> <?php } ?> </tbody></table> } For instance if i set the following 2x variables; "$varOne = $_GET[first_name]" "$varTwo = $_GET[last_name]" "$varThree = $_GET[userid]" how do i insert them both together into a DB field for example: $full = $varOne,$varTwo,$varThree (without the , ) this would then be echo as : joebloggs66985 i have the INSERT in there atm but i wanted to insert first name and last name together with there userid to generate a sort of username possibility. sorry if i didnt explain correcly I am having problems displaying individual data I am using $filename[0] to display the first data, any ideas where i am going wrong. <?php $active_keys = array(); foreach($_POST['img'] as $key => $filename) { if(!empty($filename)) { $active_keys[] = $key; } echo "". $filename[1]; } ?> Hi guys,
What I'm trying to accomplish sounds like fairly easy task but due to my poor knowledge of php this turned to be quite a challenge.
What I'm trying to do is to make a php script that will search the keywords on the multiple websites.
Websites that I will search are all web shops, selling spare part for home appliances and keywords used are usually original spare part codes.
When searching, script is searching these websites using their own search functions and not Google or other search engines.
Input for this script should be a CSV file containing list of keywords and URLs of the web shops that needs to be search for all these keywords. Here is the example: http://prntscr.com/4ebhxh Script should perform like this: It picks up the 1st keyword, browse to the URL1, uses its search, searches for the product, if it finds it, copy its price and write it back to original input CSV. If it doesn't find match (search results appear empty) it should write "no match found" and continue to URL2, URL3 and so on... When all URLs from the list are checked for the 1st keyword, scripts picks up 2nd keyword and continues on through all these keywords are not checked. This would be a resulting CSV file after the 1st keyword is checked: http://prntscr.com/4ebj52 After all data from the input CSV file are processed, script should prompt a msg and create a download link for that CSV file to be downloaded. If there are multiple matches, in other words if for one keyword some of the website searches find 2 or more products, something like "More then one match" should be written in the file. Example: http://prntscr.com/4ebkcx Please note that non of the website is using SSL and non of them requires login in order to display the prizes. This fact should make this script easier to build. Its not important for this script to run fast (its better I think to run it with some timeouts because of the server glitches and bottlenecks). What is more important is to make it automatic so one can start it over the night, over the weekends. Number of the URLs would be around 10, and list of keywords from few tens, to a few hundred. If I can provide some additional clarification and info I'm available. Of course I would be willing to pay someone to help me accomplish this task.

"<br>"; // this prints out all the values perfectly } no I just dont know how to store them so i can use them later. I have 2 websites currentweb.com copyweb.com (say) Using php can I update 2 databases and upload files in both these 2 websites ( for both these web sites I have user id and password exmaple I am uploading a file (Image), in currentweb.com can I upload it to copyweb.com at the same ( I have database and ftp password for this ) If Yes Please help with code is it possible to collect data from another website and insert it into my db?, lets say for example: http://www.imdb.com/title/tt0285331/episodes#season-1 could i somehow get the Episode name eg: Quote Episode 1: 12:00 a.m.-1:00 a.m. and the description Quote Jack Bauer is called to his office because there's a threat on the life of a US Senator who's running for President; Jack also discovers that his daughter has skipped out her bedroom window. and place that into a table in my db? any help would be great. I have created 5 websites under 5 different domains. Contents of this websites' are similar and using a same template for each one. Now I need to create an admin panel to control these websites. PHP and MySql I will use for this backend.
My problem is how can I manage these five website with one backend? Reason is I will use different domain for my backend. My all 5 client will use this same backend system to manage their own website.
So can I know from the professionals here, is it possible to display mysql data on these 5 website. If it is possible then how?
Any links to article or tutorials would be welcome and appreciated.

mysql federated storage enginebut no idea? Is it the way where do I need to go? Thank you. I can use the first while loop, but there is no data in the second while loop. Is there a better way as I have never done this before...

I have a website already in place that someone else coded and I just need to add something to. There's a form that posts to another page and then back to a sql database. What I want to do is have the form also email me the contents of the form when it is submitted. Is there a way to have a form do multiple actions? I'm not sure the best way to go about this, so if someone has some pointers, I'd really appreciate it. Thanks! Hi there im trying to set a single variable multiple rows of data that are echoed using a single variable. The trouble is i just cant seem to make it work by trying to add a while or do loop.. The variable is $alderaanfleetalt and consists of: Code: [Select] $fleetname = "FleetName"; $shipname = "Ship Name"; Which is just text stored in two other variables. The select query row of data is added the $alderaanfleetalt variable. Code: [Select] $alderaanfleetalt = $fleetname." ".$row_Alderaanfleet['FleetName']."</br>".$shipname." ".$row_Alderaanfleet['ShipName']; At the moment only a single row appears. ive tried to add a while/do loop so that multiple rows are outputted but its not working. Code: [Select] do{ $alderaanfleetalt = $fleetname." ".$row_Alderaanfleet['FleetName']."</br>".$shipname." ".$row_Alderaanfleet['ShipName']; } while ($row_Alderaanfleet = mysql_fetch_assoc($Alderaanfleet)); Im a bit lost here and not even sure it can be done this way... Any help would be ace. Thank you I have the form: Hi all, slightly confusing title! What I am trying to do is make a simple stores system whereby I can add and remove stores. It is purely php and no mySQL. My idea was to create a text file with the individual number and then include the file on the table on the page. I have worked out how to increment one value by one, but the others I am struggling with. Example I wish to have two links one which I click to increase and another to decrease the value by one. It's the multiple issue that is confusing me, I create a txt file and a php file using a variable from a submitted form (part number). The php file holds info and the text file holds the number which is default at '0' (Zero). My idea was to write some php to the file, perhaps when I click the plus it will open and write to the file + 1 .. Any guidance or points in the right direction would be greatly appreciated. Thanks. Shugs Hey Im always trying to remove code and cut corners to reduce work in the long run, soIim wondering how I could link my menu bar from say a template to ALL my php pages for my site so I don't have to write/change links on every page when I need to. Thanks Hi is it possible to update multiple records of the same table using a single hidden field with a while loop??? For example: Code: [Select] <?php if ((isset($_POST["MM_update"])) && ($_POST["MM_update"] == "form1")) { $updateSQL = sprintf("UPDATE ships SET HealthA=%s WHERE ShipID=%s", GetSQLValueString($_POST['healtha'], "int"), GetSQLValueString($_POST['shipid'], "text")); ?> <input name="healtha" type="hidden" id="healtha" value="<?php echo $row_Ships['HealthA'] + 1; ?>" /> <input name="shipid" type="hidden" id="shipid" value="<?php while($row = mysql_fetch_assoc($Ships)){ echo $row_Ships['ShipID']; }?>" /> If its not possible what else could i do to achieve this please? Thank you
Hi, I have a table of content in my page. For each row it has a check box. How do i achieve the function of when i click on submit button, those rows which are checked will be downloaded as a single pdf file. For example, for each checked row is a PDF file here. Suppose if i checked for 5 rows , 5 PDFs will be downloaded. Hi, I believe this is my first post on here. First off let me say thank you for silently helping out in the past while I keep on learning PHP. I have decided to build an image gallery, and I am having problems with the page numbering links and the breadcrumbs. Reson I decided to build my own is that I wanted a challange to learn more. I could not find anything that would intregrate with the site as I wanted it to (pulled as a function so offers some customising with options). The problem that I am having is that the <a href= tag is starting to give multipul "/"s when I only need one, so that the url at the top is coming up as http://localhost/mmv4/gallery/pics///Ax/Ax_Jo/ when I am wanting http://localhost/mmv4/gallery/pics/Ax/Ax_Jo/IMG_4244.JPG. I have used str_replace to catch //s and more, but this then adds odd slashes on the end so the page numbeing is getting odd results. some dirs have the / on the end and some do not, so the links are sometimes "visited" and others not. I beleve that the problem is generated in Code: [Select] <?php if(isset($_GET['album'])) { //load the available dirs into an array so that the sneeky users cannot get further back. $files = scandir($gal); $dirs = array(); foreach($files as $file){ if($file != '.' && $file != '..' && $file != 'thumbs') { if(is_dir($gal."/".$file)) { $dirs[] = $file; //echo $file ."<br />\n"; } } } //if(in_array($_GET['album'],$dirs)) { $album = "/".$_GET['album']."/"; $album = str_replace("..", "", $album); //} //else { // $output .= "<p>There is no album called \"$_GET[album]\", please select an album from below.</p>"; //} } or the breadcrumbs bit Code: [Select] <?php if($crumbs == 1) { //bread crums $path = $gal.$album; $path = explode("/", $path); $crumbs = array(); foreach($path as $key => $value) { if($value != ""){ $crumbs[] = $value; } } // create Breadcrumbs div $output .= "<div id=\"breadcrumbs\">"; $number = count($crumbs); $real = ""; foreach($crumbs as $num => $link) { if ($link == $gal) { $link = "Gallery Home"; } if ($num == $number -1) { $output .= $link; } else{ if ($num >= 1){ $real =""; for($x=1; $x<=$num; $x++) { $real .= "/".$crumbs[$x]; } $output .= "<a href=\"?album=".str_replace("/", "",$real)."\">".$link."</a>"." <- "; } else{ $output .= "<a href=\"?album=".str_replace("/", "",$real)."\">".$link."</a>"." <- "; } } $num +1; } //close breadcrumbs div $output .= "</div>"; } Can any one please help me shed some light on this one, I am confused.

Hi, I'm modifying the following PHP code from a Wordpress plugin: /* Byline. */ if ( $instance['byline'] ) echo do_shortcode( "<p class='byline'>{$instance['byline']}</p>" ); /* Entry title. */ if ( 'widget' !== $instance['entry_container'] && $instance['entry_title'] && $show_entry_title ) { the_title( "<{$instance['entry_title']} class='entry-title'><a href='" . get_permalink() .

Anyways basically I want to be able to "queue" functions from a class in a single call and am wondering if I am doing it correctly or if there is a better way to do it. Here is my code: <?php class test { private static $one; private static $two; private static $three; public function callOne($val){ $one .= $val; return $this; } public function callTwo($val){ $two .= $val; return $this; } public function callThree($val){ $three .= $val; return $this; } public function print(){ echo $this->one.' '.$this->two.' '.$this->three; } } ?> now when I want to call this I can do: $test = new test(); $test->callOne('one')->callTwo('two')->callThree('three'); $test->callOne('another one'); $test->print(); Is there a better way to do this or is there a different method of doing this? Just wanna make sure I am doing it right lol. |
