PHP - How To Know When Websites Generate Hidden Variables

does anyone have an example of new code that is used this day in age for combining js and PHP to produce dynamic content on a webpage?  I have looked at this from w3schools:

https://www.w3schools.com/php/php_ajax_database.asp

but I believe that XMLHttpRequest is really old.  If I rememeber my reading right, it was replaced by fetch() a long time ago.  I think i understand everything that is on that tutorial page, but I would love to see a video tutorial on this subject.  can anyone here point me to such a resource?

i have an array of website links i want to loop through each and get a certain html id foreach

whats wrong with what i did here?
Code: [Select]
foreach($links as $page) {
   $phtml = file_get_html($page);

// find all td tags with attribite align=center
foreach($phtml->find('span[id=name]') as $name)
    echo $name->plaintext.'<br><br>';
}

How is it possible for a website to know my physical location?
Some websites I've seen will have ads such as; meet singles in "HOMETOWNGOESHERE"
I'm guessing this kind of info is found from my Ip address?
Has anyone ever done anything like this in php, I'm interested to know how this works.
 

HI guys
Im developing  Health site using PHP and mysql. I want to create graphs from using data in the database on weekly basis. so please tell me what is the best method of creating graphs and charts in php
thank in advance

I'm new in php and I don't have knowledge of php.   I just want to know, whenever we download file from server to Desktop through FTP, there are whitespaces occuring in files. Like html websites, we always remove whitespaces whenever we upload the file to server after editing it. Is this step necessary for php websites also? If necessary then how to do it?

Code: [Select]
if($login_count == 1) {

while ($row = mysql_fetch_array($login_sql, MYSQL_ASSOC)) {

$_SESSION['MembersID'] = $row['members_id'];

session_register('MembersID');

}}
this works fine and logs me in on my website with the script and displays the correct id with:
                              
Code: [Select]
if(isset($_SESSION['MembersID'])){

$session_id = $_SESSION['MembersID'];

echo'<li><a href="https://members.selmgec.co.uk/">Welcome, '.$session_id.'</a></li>';

}

but how can i pass it onto another website i own, using the same database connection.

I got a good one for you guys,

I run 20 or so websites on my server all that have very similar coding structures. On all sites, I have a php script for a mysql table that logs visitors and I filter out bots(google, yahoo, etc, as many as I know of), but since many new ones are discovered weekly/monthly, I hate manually going through all sites and adding the new bot to the array of existing bots for detection. I know there are a few ways to do this, but I'd like to know the most efficient way of basically doing one function/task/opertation and it automatically updating all website's to know the new bots without manually modifying all 20 php files every time. The sites are all on the same server, but at different domains.

a few ideas, which are prob not the best
1) have a universal text file that I could update that would be located in some file on one of my sites that just has a list of all bots and then each site would read from that text file to know what bots to filter.
2) have a huge php file to execute that has all connection info/passwords for every site and runs a php script to update the corresponding website's mysql table that would hold each bot as a row in the table. the script would just add a new row with the new bot info. so then ultimately when logging visitors, it would have to read the database each time
3) try to "include" a universal .php file that's located on one of my sites that has the array of all bots. But I've tried to include a file from another domain and I know that's a security error and won't include the file as a .php, but rather the file after it's been processed.

There's gotta be a better solution. any ideas?

I have developed a form for my website that directs the user to a different site and per-populates the form on the other site with information I want.  I would like to take it one step further and make the below script fill out the form on the other site and then submit the form.  Currently it just fills out the form on the other site but does not submit it.  Is there any way to do this?

Code: [Select]
<form action="http://www.privatedutyhomecare.org/sections/consumers/locator.php" method="POST">
<input name="state" size="25" type="hidden" value="MI" />
<input name="company" size="25" type="hidden" value="Affordable HomeCare" />
<button type="submit" class="imgpx">
<img src="assets/images/logos/npda.png" alt="submit" width="51" class="nothing" height="40" />
</button>
</form>

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.

Hello,

I had made a website (PHP) for a music company  few years back. They basically sell songs from their site. Now they've faced a problem. Their site has been crawled by abmp3.com and they not only let user download songs from our site but also give a full path of a song to download.

I wonder how this happened and how to stop them from crawling our site. And its likely some other site doing same too. So please anybody help me how to overcome this problem, may be some PHP code can do this??.

Thanks

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.

Cheers
Dean

I need to know if this is even possible.  I have found conflicting information on this online. 

Anyway, here is what I want to do.  I have two websites that reside on the same dedicated server.  Both have different IP's.  www.mywebsite1.com and www.mywebsite2.com. 

I need a user that logs in at www.mywebsite1.com to be able to pass the $_SESSION from www.mywebsite1.com to www.mywebsite2.com.  Any help on this would be cool.  Thanks in advance.

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.   NOTE: I checked

mysql federated storage engine

but no idea? Is it the way where do I need to go?   Thank you.
