我做了几个快速测试(没有时间和我喜欢的hiphop一样,不幸的是;-() ;这是我得到的结果:
首先test-2.php,这是包含解析错误的内容:
<?php
echo "what with a parse error ?
注意:字符串未完成
试着用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
试着用hiphop编译,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 $end
即具有解析错误的文件无法编译 - 这是有道理的.
错误消息有一些信息存在于PHP的错误消息中 - 但不完全一样精确...
这意味着您可能希望在尝试使用hiphop编译应用程序之前尝试使用PHP:PHP提供的错误消息更具描述性.
现在,让我们尝试一些运行时错误/警告; 这是以下内容test-1.php:
<?php
error_reporting(E_ALL);
ini_set('display_errors', 'On');
if ($_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";
试图从Apache + PHP运行该文件,你会得到三个错误:(
我将文件复制到我的文档根目录 - 这意味着Apache的错误路径不一样)
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,试着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,test-1.php使用hiphop 编译该文件并在Web服务器模式下运行它,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:

现在,让我们尝试访问这三个网址; 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因为http://localhost:8080/test-1.php?test=2,我得到:
plopDivision by zero最后http://localhost:8080/test-1.php?test=3,我得到:
plop在这里,错误的迹象也不如PHP那么好...至少在默认选项中......
从hiphop的Runtime选项wiki页面判断,您可以指定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

all servers started
我应该获得更多信息......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:
因为http://localhost:8080/test-1.php?test=2,我得到:
最后http://localhost:8080/test-1.php?test=3,我得到:
plopf_file_put_contents/316: Permission denied
我没有尝试更多,但玩配置文件和--config开关看起来像一个有趣的想法;-)
注意:我在Ubuntu 9.10 64位上进行了这些测试 - 这是一个官方支持的系统; 安装很简单.
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就不是一项不可能完成的任务.
