In this blog, we will cover the first three topics. The next two processes will be covered on the next blog.

So let us begin this tutorial with reverting to an old version.

Reverting To An Old Version

If you encounter any problem after having your version upgraded, you can always go back to the previous version. You can do this using the PHP version tool in cPanel.

After upgrading your website to a higher PHP version, you may encounter some depreciation errors. This is because some functions or features used by your site have been removed. You have the option to either edit your website’s code to make it compliant to the new version or go back to the previous version.

Copying An Updated Php.ini Version

If you are using a custom php.ini file, ensure that you are using the correct file for your version:

  1. For PHP 5.3, copy the /usr/local/lib/php.ini. This is the default php.ini file.
  2. For version 5.2.17, copy the php.ini file located at /opt/php/php-5.2.17/lib/php.ini.
  3. Other versions can be found in the /opt/php directory

To copy the updated php.ini file to your public_html directory, log in to your SSH account and then use the cp command. To apply it to all subdirectories, add the following to your .htaccess file.

Replace USERNAME with your own account username:
SuPHP_ConfigPath /home/USERNAME/public_html/

If you are using custom configurations, you must reconfigure them after copying the updated php,ini file.

Correcting “500 Internal Server Error” After Upgrade

If you get a “500 Internal Server Error” after upgrading to a higher PHP version, check the .htaccess file in your public_html directory. At the end of the file, you could see text similar to the following:

# Start A2 Switcher Block
# Do not remove or modify this block! Added by PHP Switcher from cPanel to use an alternate PHP version. Contact Support for details.

<IfModulemod_suphp.c>
AddHandler application/x-httpd-php-5.4.13 .php
</IfModule>

# End A2 Switcher Block

Adding AddHandler value will help determine the PHP version for your site. Check if the correct version is indicated and the line formatting is correct. Depending on the previous configuration of your .htaccess file, you may find that the lines of text have been merged which could pose some problems.

Wrap Up

New PHP versions allow more functionality for your website. However, they are also prone to bugs that need to be fixed. You can hire dedicated PHP developers to fix the problem for you.

Developer optimizes your site with regard to everything that requires pulling you among the top search results and drawing the appropriate traffic to you. Page loading time is a chief factor in them.

Following are several ways to optimize your website in a way to reduce the page load time.

    1. You can efficiently begin by limiting yourself or your site. There aren’t only words on a web page but different components such as images, links, videos, style sheets, and much more. Whenever a website is requested, an HTTP request sent like a call, to all mentioned components. So, numerous the components, longer the page load time was taken.Try to systematize all the compulsory elements in a way that uses slighter data. Images also require a good extent of this data and require being optimized. Making use of CSS is a viable alternative but the page still loads the original size prior to converting it into the CSS type.
    2. There is patience needed when you open a webpage for the foremost time but if you do not wish to experience that lag again, ensure to use your cache memory prudently. When a webpage reloads, you don’t have to experience the full call process that takes place in the background. The browser cache which calls that Web Pages from the stored browsed history, for relatively lesser time.
    3. Moreover, you can accomplish this optimization through compression. Compression lessens the response time you receive from HTTP since it bounds the bandwidth of your webpage. Utilize links like they do not weigh on the website or its load time. The compression is much effortless because it is an element of server settings and can be simply dealt with.Images, rather than choosing CSS, can pick to be compressed to match the page size. Zip files are a best example of that compressed data. Such files have low data usage as well as can store a lot of large files like PDFs, gif, docx and .exe files.
    4. One more way to save time on page loading is through arranging your code in the finest possible way. Ensure to exclude any files, class, call actions or links that will decelerate the loading speed, and can be survived without. Organize the CSS optimally to eliminate wastage coding. Try adding the JavaScript code at the end, rather than the beginning.Certain portions of the page containing background work can be put in the end in order that they can continue loading while the site is already visible to the visitor. The user has nothing to do with the background work, so completely utilize it.
    5. There are a lot of ways to gauge loading speed of your page. Developer runs tests for you as a kind of service among numerous such services. Having knowledge of your page loading time is a best advantage. When making use of plug-ins, the tasks look to get easier at the price of loading time as well as losing traffic.

To cut that time, attempt using only a little amount of plug-ins. Try employing follow-up links if feasible or utilize plugs that perform multiple tasks. The plug-in give big load on your page and raises the site loading time and therefore must be put on a minimum use.

Set mentioned parameters for your webpage and develop a perfect place for visitors to be swiftly accessible to. It is not only your ranking or traffic which will be a boon, but also a satisfied and happy conversion rate and user feedback.

Boost Your Stock As A PHP Developer With Zend Certification

In order to become one of the most in demand PHP developers, you need to improve your skills and boost your reputation in the industry. Professionalism is one of the major criteria customers look for when they hire dedicated PHP developers. And one of the way you can do so is through certification, As a PHP developer, one of the ways you can be certified is through Zend.

What is Zend Certification?

The Zend Certified PHP Engineer is offered by the Zend company. It covers a wide range of development applications in PHP 5.5. Among the topics covered in the program include PHP Basics, Object Oriented Programming, and Security or Arrays. You can a preparatory course for the exam but it is not mandatory. You can take the exams from one of several Pearson VUE Testing Centers from across the globe.

Why Become Zend Certified?

There are several benefits of becoming a Zend certified PHP developer. Here are some of them:

  • It can confirm your skills

    For advanced PHP programmers, being Zend certified is one of the ways you can boost your professional experience. Once you pass the Zend certification exam, your name will be included in the list of other passers. Aside from that, being Zend certified can help you distinguish yourself from beginners.

  • It helps expand your knowledge

    The Zend certification program requires some preparation and studying on your part. As it covers all the basic functions of PHP, reviewing for the exam may also be a good way of learning different aspects of PHP and reviewing your knowledge.

    When you are applying for Zend certification, you will cover a lot of ground from the basic knowledge such as syntax, operators, or language constructs to the other features of PHP such as working with files, manipulating arrays and strings, and others. As a result, you may also gain a wider view of PHP itself.

What are the disadvantages of Zend certification?

  • The manner of construction

    The exam consists of around 70 questions. The Zend website provides some questions to give you a perspective of how they are really built. Some of the questions will only ask you What will the following code produce? Likewise, there are some sample codes that you need to examine.

    The sample questions can be a good gauge in checking your PHP skills since you will be exposed to real codes and be made to analyze the various commands being executed.

    However, some of the other parts of the test that do not make real sense at all. For instance, there is no point in memorizing hundreds of string array or functions when you can find properly written ones from the PHP documentation. These functions have proven inconsistent in their naming and parameter order or return values.

  • It does not prove your competence as a developer

    Yes, being Zend certified does improve your skills and experience. But that’s just about it. Your Zend certificate is not a sufficient proof of your competency and efficiency as a PHP developer. The truth of the matter is that even if you do not take the exam, you can still use your knowledge in real cases. On the aspect of being able to create programs or following best practices, your certificate may prove meaningless.

Conclusion

People hire dedicated PHP developers not because they are Zend certified but because they are able to accomplish projects. But I am not discouraging you from taking the Zend certification program, what I am saying is that you can still prove your competence without it.

PHP Coding Guidelines & Best Practices: Be a Better PHP Developer

When it comes to coding standards, every PHP development company have their own standards based on their best practices. Coding rules are necessary because if developers will use different modules and start inventing their own standards, it will become difficult to maintain the source code in the future.

Here are the reasons for using coding specifications:

  • Your co-programmers must have an understanding of the code you are producing. The coding standard serves as a blueprint for all the teams to understand the code.
  • Simplicity and clarity gained from constant coding saves you from the most common mistakes
  • Future revisions of the code will make it easier to understand
  • It is industry standard to comply to a particular standard to being more quality in software

Here are some guidelines to follow when coding in PHP:

 

  1. For indentions, limit it to 4 spaces without tabs because different computers have different tab settings. For the line length, it is best to keep the lines at approximately 75 – 85 characters long for better code readability.
  2. Control structures such as it, for, while, switch, and others should have one space between the keyword and the opening parenthesis to separate them from function calls. Always use the curly braces even when situations call for making them technically optional.
  3. When making function calls, there should be no space between the function name, the opening parenthesis, and the first parameter. There should be spaces between commas and each parameter and no space between the last parameter, closing parenthesis and semi-colon.
  4. For comments, C style and the standard C++ comments are both acceptable. However, using Perl/shell style comments are discouraged.
  5. For PHP code tags, always use <?php> as delimiter not the <? ?> shorthand. This is a requirement for PHP compliance and is the easiest way to add PHP codes on a wide range of operating systems and setups.
  6. Here are the rules for naming variables:

    • Use all lower case letters
    • Use ‘_’ to separate words
    • Global variables should be prepended with a ‘g’
    • Global constants should be in all caps with ‘_’ separators
    • Static variables may be prepended with an ‘s’.
    • Functions should not prevent static variables from being reentrant
    • Sets of declarations should be aligned
    • Statements per line should be limited to just one unless the statements are interrelated
    • Methods should be limited to just one page of code

Conclusion

These are just some of the coding rules that a PHP development company should remember. When creating your program, you should show consistency throughout the programming code. This will only be possible if you will adopt coding standards. You can come up with your own standards if you want something unique. Having a uniform coding standard ensures consistency in writing programs.

Developers will write their codes based on the rules and will not make their own style. As a result, the code will not only be easier to understand but also the developer will have an understanding of what to expect throughout the program.
