This marks the third consecutive Release Candidate iteration of PHP 5.6.0, encompassing all bug corrections reported by the expansive global PHP community.
The latest rendition introduces a multitude of enhancements and novel features designed to elevate the security and usability of PHP.
Here is an overview of the key additions featured in this update:
Integration of support for constant scalar expressions, permitting numeric and string literals or constants within static-value contexts like constant and property declarations or default function arguments.
Implementation of variadic functions using the '...' operator, rendering func_get_args() obsolete.
Introduction of argument unpacking via '...' operator, enabling arrays and traversable objects to be unpacked into argument lists when invoking functions.
Inclusion of exponentiation functionality via '**' operator, encompassing a right-associative ** operator and a **= shorthand assignment operator.
Expansion of the use operator's capabilities to import functions (via use function construct) and constants (via use const construct), in addition to classes.
Incorporation of phpdbg, an interactive debugger, as a SAPI module.
Adoption of default_charset as the default character set for encoding-specific functions such as htmlspecialchars(). Default value is UTF-8.
Enhancement of large file upload support, now accommodating files exceeding 2 gigabytes in size.
SSL/TLS improvements encompass enabling peer verification by default, incorporating support for certificate fingerprint matching, activating safeguards against TLS renegotiation attacks, and introducing numerous SSL context options for finer control over encryption protocol and verification settings.
