I am making a database and a corresponding website for the same. The website offers taking (scientific) queries from the user and searching the information (protein/nucleotide sequences, name of organism, accession id, etc.) against my database as an output.
I am done with the database and the website, even the script (HTML->PHP->Perl) fetches information asked by the user.
My Problem
Let's take for example, a database with Employee info like ID, name, age, sex, etc.
I have all the output information in an array. The problem is when I have to post it into a html output. The thing is, I can print these values like printing the complete html file with the respective tags and then opening the html file, but my web page has some buttons/options which will do something (here, print any info, drawing charts using the values like age, salary,etc.). It will also have a scroll function for displaying the information and the buttons on the bottom of the page.
So I need some basic guidance,
Should I go with dynamic pages or static?
If dynamic, is there any way I can parse the arrays from Perl to PHP?
If it's in a database, I'd go dynamic. But I don't understand why you're jumping between perl and PHP, either can do the job on it's own.
If your data is being queried into arrays in perl, parse it out into JSON or XML. Both perl and PHP have awesome parsing modules available.

I have a table with date/time, temperature and humidity data stored on a mysql database.
I have a ugly looking but working HTML one so I made a new CSS table using templates and wanted to use the looping in PHP (as in the HTML) to fetch data to the table using the table designers format. (Some datas are manually in as in the sample table photo)
I want to automate that but my PHP script has a problem and does not load the page. shows error.
Im very new to LAMP environment actually and unsure if I can use class variables inside the PHP script without changing anything.
My table looks like this without the python script: https://imgur.com/a/WmpHzMZ
The code is here: https://codeshare.io/amvPYw
(I cannot add code here, it says bad formatting everytime)
Html element tags are close like </tr>. See your end line in while loop.
I want to search on website pragmatically using PHP like as we search on website manually, enter query on search box press search and result came out.
Suppose I want to search on this website by products names or model number that are stored in my csv file.
if the products number or model number match with website data then result page should be displayed ..
I search on below question but not able to implement.
Creating a 'robot' to fill form with some pages in
Autofill a form of another website and send it
Please let me know how we can do this PHP ..
Thanks
You want to create a “crawler” for websites.
There are some things to consider first:
You code will never be generic. Each site has proper structure and you can not assume any thing (Example: craigslist “encode” emails with a simple method)
You need to select an objective (Emails ? Items information ? Links ?)
PHP is by far one of the worst languages to do that.
I’ll suggest using C# and the library called AgilityHtmlPack. It allows you to parse HTML pages as XML documents (So you can do XPath expressions and more to retrieve information).
It surely can be done in PHP, but I think it will take at least 10x time in php compared to c#.
I am trying to create multiple landing pages populated dynamically with data from a feed.
My initial thought was to create a generic php page as a template that can be used to create other pages dynamically and populate them with data from a feed. For instance, the generic page could be called landing.php; then populate that page and other pages created on the go with data from a feed depending on an id, keyword or certain string in the url. e.g http://www.example.com/landing.php?page=cars or http://www.example.com/landing.php?page=bikes will show contents that are either only about cars or bikes as the case may be.
My question is how feasible is this approach and is there a better way to create multiple dynamic pages populated with data from a feed depending on the url query string or some sort of id.
Many thanks for your help in advance.
I use this quite extensively. For example, where I work, we often have education oriented landing pages, but target each landing page to different types of visitors. A good example may be arts oriented schools looking for a diverse array of potential students who may be interested in a variety of programs for any number of reasons.
Well, who likes 3d Modelling? Creative types (Generic lander => ?type=generic) from all sorts of social circles. Also, probably gamers (Gamer centric lander => ?type=gamer). So on.
I apply that variable to the body's class, which can be used to completely reorganize the layout. Then, I select different images for key parts of the layout based on that variable as well. The entire site changes. Different fonts can be loaded, different layout, different content.
I keep this organized via extensive includes. This sounds ugly, but it's not if you stick to a convention. You have to know the limitations of your foundation html, and you can't make too many exceptions. Sure, you could output extra crap based on if the type was gamer or generic, but you're going down the road to a product that should probably be contained in its own landing page if it needs to be that different.
I have a few landing pages which can be switched between several contents and styles (5 or 6 'themes'), but the primary purpose of keeping them grouped within the same url is only to maintain focus on the fact that that's where a certain type of traffic goes to in order to convert for this specific thing. Overlapping the purpose of these landing pages is a terrible idea.
Anyway, dream up a great template, outline a rigid convention for development, keep each theme very separate, and go to town on it. I find doing it right saves a load of time, but be careful - Doing it wrong can cost a lot of time too.
Have a look at htaccess URL Rewrite. Then your user (and google) can use a url like domanin.com/landing/cars but on your server the script will be executed as if someone entered domain.com/landing.php?page=cars;
If you use feed content to populate the pages you should use some kind of caching to ensure that you do NOT reload all feed on every requests/reloads the page.
Checking the feeds every 1 to 5 minutes should be enough and the very structure of feeds allows you to identify new items easily.

A nice template engine for generating pages from feets is phptal (http://phptal.org)
You can load the feet as xml and directly use it in your template.
test.xml:
<foo><bar>baz!!!</bar></foo>
template.html:
<html><head /><body> ${xml/foo/bar}</body></html>
sample.php:
$xml = simplexml_load_file('test.xml');
$tal = new PHPTAL('template.html');
$tal->xml = $xml;
echo $tal->execute();
And it does support loops and conditional elements.
If you are not needing real time data then you can do this in a few parts
A script which pulls data from your rss feeds and stores the data somewhere (sql db?), timed by something like cron. It could also tag the entries into categories.
A template in php taking the url arguments and then adding the requested data and displaying it for the user. Really quite easy to do with php, probably a good project to use to learn as well if you are that way inclined
I have a MySQL Database of more or less 100 teachers, their names, and their phone numbers, stored in tables based upon their department at the school. I'm creating an iPhone app, and I've found that UITableViews and all the work that comes with it is just too time consuming and too confusing. Instead, I've been trying to create a web page on my server that loads all the data from MySQL and displays it using HTML, PHP, jQuery, and jQTouch for formatting.
My concept is that the separators will be by department, and the staff will be sorted alphabetically under each department. On the main page, each person's name will be clickable so they can go to ANOTHER page listing their name, email address, and telephone number, all linked so that the user can tap on the email or number and immediately email or call that person, respectively.
HOWEVER, I am completely at a loss for how I should start. Can anyone point me in the right direction for displaying the data? Am I going about it wrong in using PHP? Should I opt for something COMPLETELY different?
PHP to manage the database interaction and generate HTML is fine. There are heaps of tutorials on how to do that (e.g. http://www.w3schools.com/PHP/php_mysql_intro.asp) How to make it look nice is beyond the scope of this answer, and I'd recommend you search for table/CSS examples to get some ideas of what looks good and how they're implemented. If you need interactivity such as expanding rows or changing colors, then jQuery would be an appropriate next step, though you certainly don't need more than HTML + CSS for a nice looking table representation.
What I don't know about is the auto email/call functionality you're after, and whether you can get that "for free" from whatever is rendering the HTML. That's iPhone specific, not PHP/jQuery/etc... And I'd second Alex's advice that if UITableView is the right tool for the job then you will definitely be better off in the long run just buckling down and learning it. (And going through that will probably make pickup up other parts of the API much easier to boot.)
Instead of loading my PHP in my <body>, I created a function that retrieved the data via mysql_fetch_assoc(), which added all the information and created each individual div of data AS WELL AS injecting a <script> to $.append() the list item content for each item retrieved via the mysql_fetch_assoc(). Thanks for the responses anyway!
I have an HTML table with contents, I would like to have an feature of Edit/Delete to that table. How do I do it with PHP?
I actually think that this sounds more like a job for JavaScript, which can edit/remove rows on-the-fly and with much less code. (Implement some AJAX too, and you can edit/remove rows in database too).
But if you insist on using PHP, you might just want to add some GET parameters to the Edit/Delete links that would delete or edit those rows.
Well, there is a pure PHP way to do it, and then there is a combination of Javascript and PHP. You must use PHP one way or another if you want your changes to the database to be permanent as that is your gateway to communicating with the database (as far as I know you cannot do that with Javascript as that is client-based and runs entirely in your web browser).
If using just PHP, you must generate HTML documents for each change. E.g., you click on one cell in the table and that gets you to a new HTML page where the field is editable through an input element; or you can list all fields at once for that row and edit them all at the same time. The fields are then posted in a form to a PHP page which will take the new values and update the database (or insert new values or however you wish it to behave). Here's a tutorial for how to do this:
http://www.freewebmasterhelp.com/tutorials/phpmysql/1
You can also mix in some Javascript which allows a more interactive interface to modifying the values in a cell. However, this obviously requires more code and may be overkill for what you're trying to do. Nonetheless, here is a link which demonstrates just that and also shows the code:
http://www.java2s.com/Code/JavaScript/GUI-Components/Editabletablecell.htm
Hope this is what you're looking for.
EDIT:
Forgot that you also wished to delete content in the table. That is also explained in the first link.
If you intend to work with databases, and it seems like you have little understanding of how they work, pick up a good book like: SQL - The Complete Reference. When you have enough knowledge of SQL, look at PHP's PDO extension: http://php.net/manual/en/book.pdo.php
