[What comes after PHP?]

Just learn by trying to build something.  It's much more practical to learn this way, as you'll go through the headaches of trying to do something and not know how. Through these experiences you'll figure some stuff out -- hopefully.

 

Thanks for the reply Mahngiel, but I have done a lot more than building something actually. As, I have made a fully-functional news publishing website, with comments, poll, user profiles, and so and so, plus, a classified-ads site that works similarly with other add sites, but the problem, is that, these sites are made with spaghetti code, your know, even if they can get the job done, I need them to be on just like professionally made, with debugging, micro-optimization... 

 

I just need to know more than creating CMS's and scripts. 

[What comes after PHP?]

Sorry, for the rather-misleading title, 

 

But, I am a noob, and have been in self-teaching for the past 8 months, and I already know the basics, used mysql_ then changed to PDO, and I am learning OOP now. But, the problem is... there seems to be many things to learn in PHP, aside from PDO, OOP and the basics. Can anyone list them here, according to their difficulty level.

 

Because, I want to learn more, but I don't know where to start. PHP unit, MVC, framworks, .... 

 

 

Hope, someone got the idea

[How Can Site Get Hacked If You Protect All Get And Post Inputs ?]

@PFMaBiSmAd

 

Thanks, Since it is very hard for me to learn PDO now, can you give me an example how to verify a value?

Which means, if I need to get only string or only integer in $_GET[] function, how do I achieve that? I tried is_string, but it only checks the first letter so basically

"abc12 " is also the same as "abcde" so is there any way to check for complete string or integer?

[How Can Site Get Hacked If You Protect All Get And Post Inputs ?]

I just don't get it. If you protect the above two, other than server hacking, or if you have file uploads,

what other ways are there for a user to hack your site. Even if the user knows the directory structure of the site?

 

I built my site, and I'm about to upload it, My hosting company is one of the best, and I don't have file any uploads in the site, So, what more would you watch out for, if you were in my solution?

 

 

btw, I am using mysql so, by inputs I mean all (GET & POST ) are protected with regex, htmlentities, mysql_real_escape_string()

 

functions.

 

 

 

 

 

 

 

thanks in advance

[Do I Need To Learn Oop To Implement Pdo]

Thank for the answer, I had found that site the least difficult, but difficult still. Thanks anyway!

[Do I Need To Learn Oop To Implement Pdo]

I am trying to change from using mysql to PDO, I heard it is very secure, but I think in-order to implement PDO, one needs to learn Object Oriented Programming for PHP. Is this true? And, if so Where can I find, the simplest and easiest to understand tutorials on the web for pdo, or oop.

use the mysql built-in COUNT function, it is very easy. check out tzag.com

Yea, it is possible. But, how in the hell can we help you, if we do not even know what is in the database, that you want to output, and what is your file structure?

[Simple, Url Re-Writing Problem]

ref.php is a dispacher, file, it has included files inside it, for example, if ref.php?user is the case, the the GET function, gets user id and outputts data from mysql

[Simple, Url Re-Writing Problem]

I have a page something like: www.site.com/ref.php/index.php?user=John

 

 

I need the above to be changed, to www.site.com/ref.php/john

 

I have .htaccess file in the root directory and inside it, there is this code:

 

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f

RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule ^(.*)$ /url/index.php?username=$1

 

 

But when I browse the page: www.site.com/ref.php/john it is giving me a 404 error

 

it must be a simple mistake, because I totally know nothing about url re-writing.

 

thanks for the help

[How Do You Structure Your Functions In A File? How Many Lines Of Are Too Much ?]

In my site, I have a functions.php file and I store all functions for the site ( A news site, with memberships, profiles )

So, I am still making the site, and 80% is finished, but the I feel like the file is going to slow my site down, I just checked it and I have reached 500th line on notepad++.

 

So, I just want to know how much is too much really. What is the effect, or the best practices when putting all your functions in one file.

 

Suppose, this for instance. There are functions that are used 10 or 20 times more than other functions. In my case, every time user browses the index page, there will be atleast 1 function that will be started. ex: ( out putting an article. ) And, there are others functions that rarely get called, like user registration, login....

 

So, is it ok to separate functions in different files according to their time of use? or not?

 

 

I generally want to know, ( Since I am newbie ) how you deal with functions, and the best methods.

 

 

Thanks.

[How To Check A ' $_Get ' Value Is 100% String Or Integer?]

Thank you Jessica, I just realized that. Since, I've seen regex is used to manipulate string data. Somehow, every time I see it, it scares me.

[How To Check A ' $_Get ' Value Is 100% String Or Integer?]

Suppose there is a url ex:

 

site.com/page.php?id=*ANTHING*

 

 

How do you check if *ANYTHING* is only string ( not composed of strings and integers ) or integer only.

 

 

Because, I used is_string() function to check it, but it only checks if the first letter is a string so

 

id=?cat435 and id=?catdasd will return the same result.

 

 

How can I make sure, if a value is then only a string or integer and not a combination of both

 

 

thanks

[Xampp Does Not Display Header Errors]

thanks lily, but none of the thing you said work. Because, I can't find them all.

[How To Transfer A User To Another Page After Log-In?]

I tried that. But the css does not work. The site got defaced.

[Xampp Does Not Display Header Errors]

Just searched phpinfo() file in xampp, and there exists no option called output buffering

[How To Transfer A User To Another Page After Log-In?]

This is the structure of the file.

 

<?php include database file ?>

<link style shit or css here >

<?php php file inside there are login queries and login checkers or the script above mentioned ?>

<?php include an html file containing the html form only for login site users ?>

<div simple html for footer of the site. ?

 

Now the problem is happening at the line three, with is called login.php and contains nothing except

 

- check if user is log-in and die

- if user is not logged in, then autheniticate his/her input with database

- If user exits then, perform:

- header("location: loged-in.php")

 

 

 

I keep asking about this problem, and always the same answers. I can't understand it. This thing is driving me crazy. I've never struggle to know about PHP as much as I am doing about header errors.

[Xampp Does Not Display Header Errors]

I don't know anything about output buffering (I am a newbie). So, do you think that is the problem? Should I turn it off?

[Xampp Does Not Display Header Errors]

Hi. I am designing a CMS site, And in localhost, there are no errors even though error reporting is on and I can see many errors. But, " header already sent " are not visible, and when I uploaded my site online, I am starting to see all these errors. Is there something I am doing wrong with XAMPP?

[How To Transfer A User To Another Page After Log-In?]

The above code you see is a log-in file. It is all php inside. But in another file called login.php I have included it and other file called login_form.html which is all html

[How To Transfer A User To Another Page After Log-In?]

else if(mysql_num_rows($result)==1)  // <-- If ONE row is returned

   {

   $my_session = mysql_result ($result, 0, 'u_id'); // <-- then user is Authentic & Start session
   $_SESSION['clans'] = $my_session;

   header('location:../FINAL/index.php');  

   }

 

As you can see the above, it is a script for a log-in page, basically saying that if row is returned from my MySQL then take user to index page.

Unfortunately, I am having a header already sent error.

 

For two days, I have tried to figure out this problem but no hope.

[Counting variables and storing them in session??]

Hi everyone. I am new to PHP and this form.

 

 

I am trying to create 10 questions in my website with PHP, in which a user will only answer just by using radio buttons, after submitting all,  he will be able to see how many answers he/she got right/wrong.

 

Now, what I need to know is that, how do you make PHP count all the right/wrong passwords and display message like: You've got 4/10 or 9/10....

 

How do you make an array ( If I am correct ) to count right/wrong of all submitted values in PHP??

 

 

I would like a simple example on this one.

Thanks for the help in advance.

[get the result of a html text box before the submit is clicked]

Geez take it easy there, you sound like [DELETED]. I was just trying to help him better understand the differences in a simpler manner. You on the other hard, are confusing the asker. Plus, it is much more convenient to get the user name match from database, with separate submit button if the user is only using PHP and not Ajax.

[get the result of a html text box before the submit is clicked]

Yes, like the posted above has told you, you need AJAX it is another scripting language more complex that HTML. It is very similar to javascript

 

This is a grate place to begin learning

 

http://www.tizag.com/ajaxTutorial/

 

Good luck.

 

And, I would suggest instead of your idea, you should make a little submit button named NOT "submit" ( <input type="submit" name="check_username" )

to search for existing usernames.
