正式宣布个人主页工具(PHP 工具)1.0 版本
此工具是一组用 C 语言写的轻量的 cgi 二进制文件。他们能运行许多功能,包括:
- 在你的私有日志文件记录页面访问情况
- 实时查看日志信息
- 提供查看日志信息的友好接口
- 在你的页面展示最近一次的访问信息
- 完整的每天及总体访问统计
- 依据用户的域名限制其访问
- 依据用户的域名为页面提供密码保护
- 依据用户的电子邮箱地址追踪其访问情况
- 支持追踪引荐 URL 的 HTTP_REFERER
- 无需服务器支持即可运行 SSI (server-side includes)
- 支持不记录特定域名(比如,你自己的)的访问信息
- 轻易地创建并展示表格
- 支持在后续的文档中使用表格信息
使用该工具,你不需要:
- 你不需要访问根目录——工具安装在 ~/public_html 目录
- 你不需要在服务器启用 SSI (server-side includes)
- 你不需要使用 Perl 或 Tcl 或其他任何脚本解释器
- 你不需要访问 httpd 日志文件
使用该工具的唯一条件是你能够运行自己的 cgi 程序。如果你不知道这是什么意思,可以询问系统管理员。
借助该工具,你还可以在两分钟内实现留言板,或其他任何用于写入信息并向访客展示的表格。
该工具不受版权限制,遵循 GNU 公共许可证。是的!该工具完全免费!
查看该工具的完整演示,请访问:http://www.io.org/~rasmus。

用于 Web 应用的 C APIvoid Cos(void) {
Stack *s;
char temp[64];
s = Pop();
if(!s) {
Error("Stack error in cos");
return;
}
sprintf(temp,"%f",cos(s->douval));
Push(temp,DNUMBER);
}
于是乎,你可以这样使用它:<html><head><title>Cos Example</title></head>
<body><h1>Cos Example</h1>
<?echo Cos($input)>
</body></html>
PHP7✔ 引擎提升- 现实世界中的大多数应用程序都能获得 100% 以上的性能提升
- 内存使用量更低
原生线程本地储存 ✔ 持久的以文件为基础的二级缓存 OPCache ; --enable-opcache-file
; php.ini
opcache.file_cache=/var/tmp
; php-cli.ini
opcache.enable_cli=1
opcache.file_cache=/var/tmp
opcache.file_cache_only=1
``` $ time composer >/dev/null real 0m0.040s user 0m0.032s sys 0m0.004s $ time composer >/dev/null real 0m0.019s user 0m0.016s sys 0m0.000s $ time php -d opcache.enable=0 /usr/local/bin/composer >/dev/null real 0m0.033s user 0m0.032s sys 0m0.000s

32 级目录, 87 个文件
✔ 抽象语法树!! echo substr("abc", [1,2]);
% phan -a test.php
AST_STMT_LIST @ 1
0: AST_STMT_LIST @ 2
0: AST_ECHO @ 2
0: AST_CALL @ 2
0: AST_NAME @ 2
flags: NAME_NOT_FQ (1)
0: "substr"
1: AST_ARG_LIST @ 2
0: "abc"

% phan -a test.php
test.php:2 TypeError arg#2(start) is int[] but substr() takes int
✔ 返回类型function get_config(): array {
return 42;
}
get_config();
✔ 强制标量类型function logmsg(string $msg, int $level, float $severity) {
var_dump($msg);
var_dump($level);
var_dump($severity);
}
logmsg(1, "2.5", 3);
✔ 严格标量类型declare(strict_types=1)
logmsg(1, "2.5", 3)
致命错误:传给 logmsg() 的首个参数必须是字符串类型,此处是整型。
✔ 匿名类return new class($controller) implements Page {
public function __construct($controller) {
}
};
class MyObject extends MyStuff {
public function getInterface() {
return new class implements MyInterface {
};
}
}
✔ Null 合并操作符$a = NULL;
$b = 1;
$c = 2;
echo $a ?? $b;
echo $c ?? $b;
echo $a ?? $b ?? $c;
echo $a ?? $x ?? $c;
✔ 飞船操作符 (Spaceship Operator)|=| Tie Fighter
k=k Tie Interceptor
<==> Tie Bomber
<=> Tie Advanced X1 ✔
function cmp_php5($a, $b) {
return ($a < $b) ? -1 : (($a >$b) ? 1 : 0);
}
function cmp_php7($a, $b) {
return $a <=> $b;
}
✔ 致命错误中的特例function call_method($obj) {
$obj->method();
}
call_method(null);
try {
call_method(null);
} catch (EngineException $e) {
echo "Exception: {$e->getMessage()}\n";
}
✔ 零成本断言function test($arg) {
assert($arg > 20 && $arg < 110, "$arg is invalid");
}
ini_set('zend.assertions',0); test(16);
ini_set('zend.assertions',1); test(17);
ini_set('assert.exception',1); test(18);
Warning: assert(): 17 is invalid failed in /home/rasmus/assert.php on line 3
Fatal error: Uncaught AssertionError: 18 is invalid in /home/rasmus/assert.php:3
Stack trace:
#0 /home/rasmus/assert.php(3): assert(false, '18 is invalid')
#1 /home/rasmus/assert.php(13): test(18)
#2 {main}
thrown in /home/rasmus/assert.php on line 3
; Completely skip compiling assert() calls
; (can only be set in php.ini)
zend.assertions = -1
✔ 新增 Closure::call()$f = function () {
return $this->n;
};
class MyClass {
private $n = 42;
}
$myC = new MyClass;
$c = $f->bindTo($myC, "MyClass");
$c();
$f = function () {
return $this->n;
};
class MyClass {
private $n = 42;
}
$myC = new MyClass;
$f->call($myC);
✔ 移除诸多弃用功能 (PHP 4 代码将会崩溃!)
- 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)
- $is_dst parameter of the mktime() and gmmktime() functions
- # style comments in ini files (use ; style comments instead)
- String category names in setlocale() (use LC_* constants instead)
- Unsafe curl file uploads (use CurlFile instead)
- PDO::PGSQL_ATTR_DISABLE_NATIVE_PREPARED_STATEMENT driver option
(use PDO::ATTR_EMULATE_PREPARES instead)
- CN_match and SNI_server_name stream context option (use peer_name instead)
✔ 新的保留字:- bool
- int
- float
- string
- null
- false
- true
- resource
- object
- mixed
- numeric
✔ Windows 系统下支持64位整数✔ 清除边缘情况下整型溢出/下溢、✔ 在64位版本中支持长度大于 2^31 字节的字符串✔ 无效数值型解析错误$mask = 0855;
✔ 统一变量语法
$this->$belongs_to['column']
$this->{$belongs_to['column']}
$foo()['bar']()
[$obj1, $obj2][0]->prop
getStr(){0}
$foo['bar']::$baz
$foo::
