✔ engine improvements
- 100%+ performance gain on most real-world applications
- Lower memory usage, sometimes drastically lower
✔ Persistent secondary file-based cache for OPCache

$f->call($myC);✔ Removal of many deprecated features
(Your PHP4 code will break!)
- ext/ereg (use ext/pcre instead)
- preg_replace() eval modifier (use preg_replace_callback() instead)
- ext/mysql (use ext/mysqli or ext/pdo_mysql instead)
- Assignment of new by reference
- Scoped calls of non-static methods from incompatible $this context
- dl() in php-fpm
- set_magic_quotes_runtime() and magic_quotes_runtime()
- set_socket_blocking() (use stream_set_blocking() instead)
- mcrypt_generic_end() (use mcrypt_generic_deinit() instead)
- mcrypt_ecb, mcrypt_cbc, mcrypt_cfb and mcrypt_ofb
(use mcrypt_encrypt() and mcrypt_decrypt() instead)
- datefmt_set_timezone_id() and IntlDateFormatter::setTimeZoneID()
(use datefmt_set_timezone() or IntlDateFormatter::setTimeZone() instead)
- xsl.security_prefs (use XsltProcessor::setSecurityPrefs() instead)
- iconv.input_encoding, iconv.output_encoding, iconv.internal_encoding,
mbstring.http_input, mbstring.http_output and mbstring.internal_encoding
(use php.input_encoding, php.internal_encoding and php.output_encoding instead)
- $is_dst parameter of the mktime() and gmmktime() functions
- # style comments in ini files (use ; style comments instead)
- String category names in setlocale() (use LC_* constants instead)
- Unsafe curl file uploads (use CurlFile instead)
- PDO::PGSQL_ATTR_DISABLE_NATIVE_PREPARED_STATEMENT driver option
(use PDO::ATTR_EMULATE_PREPARES instead)
- CN_match and SNI_server_name stream context option (use peer_name instead)✔ New reserved words:
- bool
- int
- float
- string
- null
- false
- true
- resource
- object
- mixed
- numeric
✔ 64-bit integer support on Windows
✔ Cleanup edge-case integer overflow/underflow
✔ Support for strings with length >= 2^31 bytes in 64 bit builds.
✔ Parse error on invalid numeric literals
$mask = 0855; // Parse error: Invalid numeric literal✔ Uniform variable syntax
// left-to-right
$this->$belongs_to['column']
// vs.
$this->{$belongs_to['column']}
// support missing combinations of operations
$foo()['bar']()
[$obj1, $obj2][0]->prop
getStr(){0}
// support nested ::
$foo['bar']::$baz
$foo::$bar::$baz
$foo->bar()::baz()
// support nested ()
foo()()
$foo->bar()()
Foo::bar()()
$foo()()
// support operations on arbitrary (...) expressions
(...)['foo']
(...)->foo
(...)->foo()
(...)::$foo
(...)::foo()
(...)()
// two more practical examples for the last point
(function() { ... })()
($obj->closure)()
// support all operations on dereferencable scalars
// (not very useful)
"string"->toLower()
[$obj, 'method']()
'Foo'::$bar✔ Unicode Codepoint Escape Syntax
echo "\u{202E}Right-to-left text";
echo "\u{1F602}";Right-to-left text😂
✔ ICU IntlChar class added to intl extension
✔ CSPRNG

// PHP 7.0 42M no opcache
// PHP 7.0 6M with opcache enabled- Much more cpu cache friendly
- New memory allocator similar to jemalloc
- Faster hashtable iteration API
- Array duplication optimization
- PCRE JIT enabled by default
- Fast ZPP (ZendParseParameters) implementation
- Faster stack-allocated zvals (instead of heap)
- Optimized VM calling
- Global register variables with gcc 4.8+
- plus hundreds of micro-optimizations

Full Vagrant Debian Dev Environment
Or if you prefer Docker:
Install Vagrant and Virtualbox
Then:
$ git clone https://github.com/rlerdorf/php7dev.git
$ cd php7dev
$ vagrant up
... (takes a bit - it is downloading 1.5G)
$ vagrant sshIt will NAT, DHCP and also has a fixed address of 192.168.7.7
http://192.168.7.7/ will show you the PHP 7 phpinfo() page
Now you have a working Rasmus-approved dev box on your network
Switching PHP versions is trivial
