Should one learn object oriented programming first, before getting to learn a framework?   I have been interested in CakePHP.

Per line 79 of the latest php.ini file (http://git.php.net/?...duction;hb=HEAD), the production php.ini file is recommended for both production and development.  Agree?   I would like to know the “typical” recommended changes to this file for both production and development.  My requirements should be assumed typical with the following qualifications: Installed using yum on Centos Apache/2.2.15 MySQL (PDO) Either a physical machine or VPS (not a shared host) Primary US market Hopefully, this provides enough description, and if you still feel it totally depends on each individual’s unique needs, please let that remain unsaid.   Below is my initial assessment: Line 445: Change error_reporting to E_ALL for development only. Line 462: Change display_error to On for development only. Line 473: Change display_startup_error to On for development only. Line 568: Leave error_log blank so they go to the SAPI Error Logger (what does this mean?) Line 656: Change post_max_size if specifically needed for the application.  Ideally, this would be changes in a particular script, however, I don’t think this is possible. Line 676: Should default_charset remain at “UTF-8”? Line 799: Change upload_max_filesize if specifically needed for the application.  Ideally, this would be changes in a particular script, however, I don’t think this is possible. Any other recommended changes?   Thank you

Hey,

I have always wondered if there is a correct way of displaying variables inside html. Typically I would echo each variable inside php tags when displaying outside of a loop but what would you recommend for a while loop while more than say 5 variables to display?

Code: [Select]
echo "<tr><td>".$var1."</td></tr>";
OR
Code: [Select]
<tr><td><?php echo $var1; ?></td></tr>

I typically structure my applications something like the following.  I lump general functionality into a given component.  For instance, I might have com_users component which deals with user administration, and implements the ability to view a list of users, view a given user, delete a user, edit a user, etc.  This structure was borrowed long ago from my learning PHP Joomla days which I no longer use.  index.php figures out which component is being accessed, evokes the controller which gets data from the model and sends the data to the view.  The view defined in each component only deals with the central content, and mainTemplate.php deals with the peripheral.

First question.  Is there anything inherently wrong with this approach?

Second question.  I am looking to start using Twig.  Would this same structure work?  I would replace /var/www/html/lib/templates/mainTemplate.php with a Twig file, and replace var/www/components/component1/views/view-1-1.php, etc with Twig files which extends the main Twig template.
 

/var/www/components/component1/controllers/controller-1-1.php
/var/www/components/component1/controllers/controller-1-2.php
/var/www/components/component1/models/model-1-1.php
/var/www/components/component1/views/view-1-1.php
/var/www/components/component2/etc/etc
/var/www/html/lib/templates/mainTemplate.php
/var/www/html/lib/templates/mainCSS.css
/var/www/html/lib/js/someJSforAllComponents.js
/var/www/html/lib/components/component1/js/someJSForComponent1.js
/var/www/html/index.php

For PHP 7.4, what is the recommended session length that I should be using to have the best security?

In DEV< in my php.ini file, session.sid_length = 26

According to the comments above that, it sounds like you can go up to 256.

Is it fair to assume that larger is more secure?

Also, if I set it to a larger size like 256, is tehre any risk of breaking things on my (VPS) web server running WHM/cPanel?

I look at my phpinfo() output, and it has ISO-8859-1 and ISO-8859-15 all over it.  UTF is not listed once.   Furthermore, mb_internal_encoding() displays it as ISO-8859-1.   For the most part, I stick to the default settings unless I have a specific reason to change.   Should I be changing php.ini to use UTF-8?  If so, any specific advice how to do so?  This whole encoding issue has been causing me major grief today

http://php.net/manua...ssword-hash.php shows a simple example to hash a password using BCRYPT.  I've read different posts recommending CHAR(60), BINARY(60), BINARY, and even BINARY(40).   What are the pros and cons of using one datatype over another?

<?php
/**
 * In this case, we want to increase the default cost for BCRYPT to 12.
 * Note that we also switched to BCRYPT, which will always be 60 characters.
 */
$options = [
    'cost' => 12,
];
echo password_hash("rasmuslerdorf", PASSWORD_BCRYPT, $options)."\n";
?>  

 

Hey PHPFreaks!

I'm designing an online application using OOP. This is by no means my first application, but it is using Object Oriented techniques, so I come to you helpful folks with a question.Essentially, I would like to be able to find out about recommended ways to approach page templates in a class design, as well as other general good class design practices specific to  server-side languages.

So, without further ado, what is considered a good/recommended method of approaching template design using OOP? For example, a base template class which can be extended for multiple themes, so additional themes don't have to recreate the core functionality if they decide not to change it. It seems that there are a lot of methods to approach it, which is why I'm here!

Any help you can provide would be greatly appreciated!

I've been following http://nvie.com/post...branching-model, which recommends master, release, and develop branches, in addition to hotfix and feature branches. Since I work with another developer only, we did not use release branches as staging area but used everything else.   Well, to ease on merges, the new idea is as such:  use only master branch, and get rid of all others.  Feature and hotfix branches can branch off of master and be merged back into master.  So in short, only have one main branch called master, and remove the develop branch.   Since we have {local, develop, production} servers, this will not impact actual development and testing. Removing 'develop' branch will however remove that "extra" intermediate step between the master branch and feature branches   Do you see any problems with this?  Or it's "to each his own, however you want to use git, use it" type thing?

I need to configure my SMTP mail port so I can use mail() function to send out e-mails.  However, I am confused as to which php.ini to configure.  I see four files when I do a search under C:\WAMP\
php.ini (C:\wamp\bin\apache\Apache2.2.11\bin)
php.ini (C:\wamp\bin\php\php5.3.0)
php.ini-development (C:\wamp\bin\php\php5.3.0)
php.ini-production (C:\wamp\bin\php\php5.3.0)

Thanks

Hello,

I have a database with the following tables:

students       groups          exams           examDay      relation         master             detail
=======     =====          =====         =======     ======        ======          =====
idStudent    idGroup           idExam         idExDay        idRelation      idMaster          idDetail
idGroup       groupName     examName   exDate         idGroup          idGroup           idMaster
studName                                                                   idExDay          idRelation        idExam
                                                                                   idExam           idStudent
                                                                                   coursesAtt      idExDay

I am trying to make a report from the Master and Detail tables that will have the table header like this:

Group | Examination Date | Student Name | Exam1 | Exam2| .... | Exam n

in which Exam1, Exam2,... are the exams names and they had to take the values from coursesAtt column.

Is this possible? I could make a view (doing joins and group by) by the results will be displayed on row. That's why I ask for your help.

Thanks

My application has 3 user types. Admin , User and Super Admin. Users can register as either Admin or User. Each user type has different UI and functionality.
The problem:
If a particular type of user reports a problem/bug in his/her login, it is difficult to pin point to the exact problem. So if I could able to login as that user, then it will be very easy to point out the bug/problem.

So I'm looking for some kind of master password. Using any username and the master password I should be able to login AS that user.

Any suggestions..?

I want to create a master-detail page using PHP. Rather than getting data from a MYSQL database, I want to get the data from an associative array. Is this possible? Please someone show me the way forward. Please help.
