HipHop 在 C 可执行文件中编译 PHP。PHP 错误会发生什么?
是不是更难调试?
编辑:我浏览了文档,但没有找到任何东西
我做了几个快速测试(不幸的是,没有时间玩嘻哈音乐,不幸的是;-();这是我得到的结果:
首先,这是 的内容test-2.php
,其中包含一个解析错误:
<?php
echo "what with a parse error ?
注意:字符串未完成
尝试用 PHP 运行它,我得到:
$ php test-2.php
PHP Parse error: syntax error, unexpected $end, expecting T_VARIABLE or T_DOLLAR_OPEN_CURLY_BRACES or T_CURLY_OPEN in /home/squale/temp/hiphop-php/tests/test-2.php on line 5
Parse error: syntax error, unexpected $end, expecting T_VARIABLE or T_DOLLAR_OPEN_CURLY_BRACES or T_CURLY_OPEN in /home/squale/temp/hiphop-php/tests/test-2.php on line 5
尝试用 hiphop 编译它,我得到:
$ /home/squale/temp/hiphop-php/hiphop-php/src/hphp/hphp test-2.php --keep-tempdir=1 --log=3
running hphp...
creating temporary directory /tmp/hphp_JdsWcU ...
parsing inputs...
parsing ./test-2.php...
parsing inputs took 0'00" (0 ms) wall time
running hphp took 0'00" (154 ms) wall time
Exception: Unable to parse file: ./test-2.php
(Line: 5, Char: 0): syntax error, unexpected $end
即带有解析错误的文件无法编译——这是有道理的。
错误消息包含 PHP 错误消息中存在的一些信息——但并不完全准确......
这意味着您可能想在尝试使用 hiphop 编译您的应用程序之前尝试使用 PHP:PHP 给出的错误消息更具描述性。
现在,让我们尝试一些运行时错误/警告;这是内容test-1.php
:
<?php
error_reporting(E_ALL);
ini_set('display_errors', 'On');
if ($_GET['test'] == '1') {
$data = (object)array(10);
echo $data[0];
} else if ($_GET['test'] == '2') {
echo 10/0;
} else if ($_GET['test'] == '3') {
file_put_contents('/bin/non-allowed', 'hello !');
}
echo "plop\n";
尝试从 Apache+PHP 运行该文件,您会得到三个可能的错误:(
我将文件复制到我的文档根目录——这意味着对于 Apache 的错误,路径将不同)
首先,打电话给http://localhost/temp/test-1.php?test=1
我:
Fatal error: Cannot use object of type stdClass as array in /home/squale/developpement/tests/temp/test-1.php on line 8
而且,尝试http://localhost/temp/test-1.php?test=2
我得到:
Warning: Division by zero in /home/squale/developpement/tests/temp/test-1.php on line 10
plop
最后,http://localhost/temp/test-1.php?test=3
我得到:
Warning: file_put_contents(/bin/non-allowed) [function.file-put-contents]: failed to open stream: Permission denied in /home/squale/developpement/tests/temp/test-1.php on line 12
plop
现在,用 hiphop 编译该test-1.php
文件并在 web-server 模式下运行它,我在编译阶段得到了这个,这意味着它没问题:
$ /home/squale/temp/hiphop-php/hiphop-php/src/hphp/hphp test-1.php --keep-tempdir=1 --log=3
running hphp...

然后,启动服务器:
$ /tmp/hphp_xXZ8US/program -m server -p 8080
Could not mlockall
loading static content...
loading static content took 0'00" (0 ms) wall time

现在,让我们尝试访问这三个 URL;首先,打电话给http://localhost:8080/test-1.php?test=1
我:
Unhandled error: Invalid operand type was used: not ArrayAccess objects.
在我启动服务器的控制台中对于http://localhost:8080/test-1.php?test=2
,我得到:
plop
Division by zero
最后,对于http://localhost:8080/test-1.php?test=3
,我得到:
plop
在这里,错误指示也不如 PHP 好……至少在默认选项下……
从 hiphop 的Runtime options wiki page来看,您可以指定一个包含一些选项的配置文件。
这是config.txt
我使用的内容:
Log {
Level = Verbose
NoSilencer = true
AlwaysLogUnhandledExceptions = true
RuntimeErrorReportingLevel = 6143
Header = false
InjectedStackTrace = true
NativeStackTrace = true
MaxMessagesPerRequest = -1
}
ErrorHandling {
CallUserHandlerOnFatals = true
NoInfiniteLoopDetection = false
NoInfiniteRecursionDetection = false
MaxStackDepth = 1000
ThrowBadTypeExceptions = true
ThrowNotices = true
NoticeFrequency = 1 # 1 out of these many notices to log
WarningFrequency = 1 # 1 out of these many warnings to log
AssertActive = false
AssertWarning = false
}
重新启动服务器,使用--config
开关指向该文件:
$ /tmp/hphp_xXZ8US/program -m server -p 8080 --config=config.txt
Could not mlockall
loading static content...
loading static content took 0'00" (0 ms) wall time
page server started
admin server started
all servers started
我应该得到更多信息......让我们再次尝试我们的三个请求。
首先,打电话给http://localhost:8080/test-1.php?test=1
我:
对于http://localhost:8080/test-1.php?test=2
,我得到:
最后,对于http://localhost:8080/test-1.php?test=3
,我得到:
plop
f_file_put_contents/316: Permission denied
我没有尝试更多,但是使用该配置文件和--config
开关看起来是一个有趣的想法;-)
注意:我在 Ubuntu 9.10 64bits 上进行了这些测试——这是一个官方支持的系统;安装非常简单。
这意味着您可以尝试这些,在虚拟机中进行安装,例如:只要您对 Linux 和编译软件有所了解,安装 hiphop 并非不可能完成的任务。
