The sockets extension in PHP 7.2 is able to lookup address information, and perform actions like connecting, binding, and explaining. Support for Extended Operations has been added to the LDAP extension. Extension of PDO’s string type to support the national character. Supports trailing comma in multi-line arrays. That means you can skip or override the type hinting without getting an error. It is mainly used for passwords, encryption, decryption, and signatures. Sodium Library included in core, which is a cross-platform library. #DIFFERENCES BETWEEN PHP 5.2 AND 7.3 PASSWORD#
Argon2 can be used as a password hash instead of the Bcrypt Algorithm.Until now only a class could be type hinted. Using classes can be made hidden from outside the class.
Visibility modifiers can be specified for class contacts. Multiple exceptions are separated using a single ‘pipe’ symbol. You can now handle multiple Exception Types in the single catch block. It helps in better error handling and improves performance. You can now create a closure from any callable function. A nullable type can be used as Type Declaration. list() previously only supported numerical values, now keys can be specified while destructuring. Arrays can now be destructured using syntax in place of the list() syntax. Cryptographically Secure Pseudo-Random Number Generator: CSPRNG is an API used to generate secure random numbers that can be used to create random passwords. Introduction of New Operators: Some of the newly introduced operators are Spaceship Operator and Null Coalesce Operator. Instead of throwing a fatal error and completely stopping the program, it now allows an exception.

Type Declaration: With the implementation of type declaration it becomes easier to read and offers better control on the overall program. #DIFFERENCES BETWEEN PHP 5.2 AND 7.3 CODE#
Better speed: PHP 7.0 code uses less memory and delivers better performance than 5.6, with almost half response time. Let’s take a closer look at what each of these versions offers individually. PHP 7.0 is twice as fast as PHP 5.6, and PHP 7.3 is 31% faster than version 7.0. Easily handles fatal and catchable fatal errors hence make the coding and debugging easier. PHP 7.0 and above execute your code faster and it also requires fewer servers to serve the same amount of users. #DIFFERENCES BETWEEN PHP 5.2 AND 7.3 HOW TO#
Find how to check PHP version by reading this article Advantages of PHP version 7.0 and above versions: It was first developed in 1994, but its new versions are coming with advanced features for better performance and speed. It is an open-source general scripting language which makes it appropriate for creating web applications. PHP is the most popular coding language which is widely used. HHVM is now no more in use with the rise of latest versions of PHP namely 7.1, 7.2 and 7.3 which are already providing better performance results, as HHVM was an unnecessary burden and intermediary process on the performance, which increases the overall load time.
In previous articles, we compared HHVM with PHP 7.0 and PHP 5 vs PHP 7, where HHVM was good in site speed performance. We keep updating this article with the new updates technology.
