PHP 7 Is Now Released – Biggest Release In Years With 100% Performance Speedup

With the evolving websites, internet services, servers and providers, it would seem to be stupid to stick to the same old development techniques.

PHP Developers seemed to be acutely aware of the fact and it seems like PHP has decided to embrace some changes. Since the last major update of 2004, the release of PHP 7 is the new biggest release in years, and the wait has been worthwhile. Everyone has been talking about this latest update and what it entails, so let’s just see the list of acclaimed improvements, shall we?

Fun Fact: PHP supports about 81.7% of the public websites.

  • Improved Performance: PHP 7 is twice as fast as PHP 5.6. And that is The developers have completely refactored the PHP codebase and that has given increased efficiency in the speed department.
  • Significantly Reduced Memory Usage: Not only is the latest update fast, but it takes lesser memory space. The new codebase has a remarkably lower degree of memory consumption.
  • Zend Engine: One of the most exciting new features is the Zend engine which promises a world of benefits to websites. The latest association between Zend and PHP is something that was anticipated for long. As quoted, “With this release, we essentially started from scratch. We knew we had to do something big with PHP,” said Zeev Suraski, co-founder of Zend and CTO of Rogue Wave.
  • Abstract Syntax Tree: This update makes the data type independent of any particular structure or coding – this marks a great improvement in the latest update by giving uniform variability in the syntax.
  • Consistent 64-bit Support: This is not a drill. Yes, the new update provides continuous 64-bit support.
  • Improved Exception Hierarchy: The new hierarchy functions under the Throwable class, it catches i.e. blocks all exceptions and errors. These errors are specific in nature, and thus, it is no longer required to deal with each error separately as an aggregate of errors and exceptions can be dealt with in one go
  • Errors Converted Into Exceptions: Most of the fatal errors, that could make the complete code bogus, can now be converted into exceptions under the Throwable Interface and can be dealt as cumulative specifics.
  • Secure Random Number Generator: PHP contained random number generators in the past, but now they have created a comprehensive generator and have applied it into the operating system, making it a secure way of generating random data.
  • Removed Old SAPIs and Extensions: The new PHP has discarded the old Speech Application Programming Interfaces and other extensions which were majorly unsupported.
  • Null Coalescing Operator: This is a revolutionary hack to check whether the value is set or is null within the inline comparison. Instead of using isset, the updated form of the language now uses “??” where the feedback will tell whether the value is set or null.
  • Return and Scalar Type Declarations: The new Type declarations make it easier to read and helps maintaining the data as it was intended to be. Scalar type provides the developers with better input consistency of function/method interface, while the return type ensures a better output consistency.
  • Anonymous Classes: Anonymous classes are immensely useful to define a class and provide an instance of the object inline.
  • Zero Cost Asserts: The assertions within development are optimized in such a way that they do not add to the product costs, and can thus be aptly described as zero cost.

These are only a few of the improvements that have been seen with the latest version of PHP.

The founder is quite confident about the latest update and has been quoted as saying, “Theoretically, you could turn off half the servers in your data center (after the upgrade) and still have the same performance as was experienced prior to moving to version 7.0.0.”

That sort of self-confidence seems really promising. But of course, it will take time for all of the developers to start using PHP’s latest version. It would seem to be a perfect step to indulge in right now, because the latest update of PHP marks the onset of a new revolution to give optimum speed with the use of minimum memories.
