Difference between PHP5 and PHP7
PHP5: PHP5 came four years after the release of PHP4 and it had a lot of improvements and new features, but the release of PHP7 has outdated its features. In PHP5 there was an option to pass the object by reference and not just by the value. The framework of MySQL was also reworked in this one, there were a lot of changes that were made to support the latest extension of MySQL.
The performance of PHP5 is comparatively low than PHP7 and there is no provision for the return type in it. In PHP5 handling fatal error was a tough job for the developers. There was a need for individual declaration for the common spaces in this one, and it didn’t support 64-bit integers. The concept of anonymous class was missing in this one and for comparison, the developer had to use a lot of operators. If there is no value available to return then to return null values the developer had to write explicit code.
