PHP is one of the few server-side scripting languages that have evolved quickly because of being the favored platform for web development. Unlike previous versions,  It currently contains all the components for being a completely robust language be it adaptability or dynamic design. interestingly the latest PHP version fully supports the OOP concept.

A bunch of best practices for the development of modern PHP applications will truly help you utilizing this well known for web application development. On behalf of my experience, I would recommend the following practices to be included in your PHP development.

Password Hashing
 Unfortunately, a majority of users are neither serious nor aware of the significance of solid passwords. In case the database is compromised then user privacy will be at risk but using password hashing you can resolve the security concern. With the recent leap in technical advances md5() is more a thing of past as hackers are now capable of millions of combinations per second to crack the password on a single GPU. hashing algorithm will make it almost impossible for hackers to crack user password and, you will still be able to match the generated hash with the original password in the future. This makes PHPass a good choice for implementing password hashing. Let see how to do about it.
Step 1- Install PHPass. Get PHPass here.
Step 2- Include the file(PHPass)
Step 3- Initiate the class
Step 4- Set Password Length
Step 5- Set the Password
Step 6- Hash the password
Step 7- Take the hash from the browser (to store in the database)
Step 8- Use the CheckPassword method (to ensure hash matches an unhashed password)

Email Validation
The validation of email holds utter significance as far as user contact records are concerned. It is quite a simple task that sometimes is considered difficult. Consider the below code snippet for this.  It is a perfect and quicker approach to ensure email validation.

Use Namespace
PHP script doesn’t allow two or more classes with precisely the same name.  If you are developing a big project where you require connectivity between two databases in a single project and there are numerous classes with the same name at that point utilizing namespace you can limit rather eliminate any ambiguity completely hence, avoiding any unwanted class name collision while calling them.  It shows the smart programming skills that the program has shown that there is a good command over OOPs concepts.

Class Autoloading
Defining each PHP class inside a separate file is prescribed the coding practice. A class characterized in a different class is first required before it can be used for object creation. When there are various separate classes it will end up in the huge number of a class requiring in each script thereby, messing up the code maintenance. It can be safely avoided by configuring PHP with the addition of the auto lodge function to load class files on demand automatically.
Use PHP to look forward to answering your questions and comments about the right approach towards modern web development.
If any information you need to get included I will update this article with it. In the meanwhile, I would also suggest you not sticking to the usage of short tags and leave an impression of unprofessional outlook. Keep in mind that the PHP interpreter treats all unquoted strings in an array index as constants and may be incorrectly auto-define them. This has no sudden impact, but it can delay execution.
