v5.1.2

Built-in PHP library included in Swoole v5.1.2.

Removed:

• Dropped support for PHP 7 (from PHP 7.2 to 7.4). PHP 7 is not supported in Swoole v5.0.0 and later; there is no need to support PHP 7 in Swoole Library anymore.

Fixed:

• Fix return type of method \Swoole\FastCGI\HttpRequest::withBody(). (commit)
• Fix return value of method \Swoole\Server\Admin::start(). (commit)
• Fix method \Swoole\MultibyteStringObject::ipos(). (commit)
• Fix incorrect operator precedence used in method \Swoole\Coroutine\Admin::start(). (commit)
• Fix issue #164 : set_charset() should be called only if DB connection succeeds. (thanks @timaelliott)

Changed:

• MR #160: Allow to pass array key/index to the callback function of function \Swoole\Coroutine::map(). (by @maxiaozhi)
• MR #166: Support configurable options for Redis. (by @sy-records)
• Add option write_func to class \Swoole\Constant. (commit)
• Improved type declarations and return types.
