As I''m learning PHP, I''m making a fair number of mistakes in syntax.

In perl, you can turn on reading these errors from the browser by
adding this:

use CGI::Carp ''fatalsToBrowser'';

Is there something like this in PHP?

Or do I need to find the php.ini file and look to see where the error
log is?

I spent some time trying to figure out why my class constructor
crashed until I found that I was writing php5 on a php4 setup. What is
most of the established base, is it 4 or 5? I see in the php docs that
some examples use 5.3, considering that the latest stable release is 5.2
I can see how there might be a lot of hair lost!

Any recommendations on creating form elements? I''ve always used
CGI.pm which handles all the gotchas. Is there anything that comes with
the standard php install? All I really need is radio, select, checkbox
and text... I''m used to writing what I need, but I''m also used to not
reinventing a wheel that was written by someone far smarter!
Is there a standard include_path being used? Are there any standard
extensions for included libararies, generally I''d like them to be seen
*only* by the parent script.

在PHP中，默认情况下会将错误消息打印到浏览器（如果使用CLI版本，则打印到

控制台）。使用error_reporting指令

，您可以控制应显示哪些类型的错误。在开发

机器上，该指令应设置为php.ini中的E_ALL | E_STRICT。

还要确保display_errors已打开。

In PHP error messages are printed to the browser by default (or to the
console if you use the CLI version). With the error_reporting directive
you can control which types of errors should be shown. On a development
machine this directive should be set to E_ALL|E_STRICT in the php.ini.
Also make sure that display_errors is turned on.

或者我是否需要找到php.ini文件并查看错误
日志的位置？

Or do I need to find the php.ini file and look to see where the error
log is?

默认情况下没有错误日志，但你可以启用它。

By default there is no error log, but you can enable it.

PHP 4已经死了，最后一次支持将在几周内结束。

之后将没有更多的安全性修复已发布。因此，再次编写PHP 4脚本绝对没有意义。使用最近的5.2

。

PHP 4 is dead, the last support for it will finally end in a few weeks.
After that there will be no more security fixes released. So there''s
absolutely no point in writing PHP 4 scripts anymore. Use a recent 5.2
instead.

5.3将引入两个主要功能，即向后移植来自PHP 6，

但它还没有发布。这本手册已经包含了简短的注释，甚至包含有关即将发布的功能的完整文档，这并不罕见，因为很多人已经使用5.3甚至6进行测试。

5.3 will introduce two major features that were "backported" from PHP 6,
but it''s not released yet. It''s not unusual that the manual already
contains short notes or even full documentation about coming features,
because many people already use 5.3 or even 6 for testing.

有各种类和库用于创建和使用PHP维护表单。

。我不推荐一个，因为我使用自己的

代码。您可以尝试Google搜索。

There are various classes and libraries out there for creating and
maintaining forms with PHP. I can''t recommend one, since I use my own
code. You could try a Google search.

不确定你的意思。

在配置中设置：

display_errors = on

error_reporting = E_ALL | E_STRICT


您也可以在运行时使用ini_set（）设置这些，但语法错误将在代码运行时遇到
，所以它是'尝试通过在脚本本身设置它来捕获它们是没有用的。使用php.ini / httpd.conf /

..htaccess文件来设置该配置。


您也可以从命令行进行简单检查你有那个

可用：


php -l / / file / to / check


（其中是使用新的

（版本）编辑器时设置/创建的第一个工具之一。

Set these in the configuration:
display_errors = on
error_reporting = E_ALL | E_STRICT

You can also set these at runtime using ini_set(), but syntax errors will
be encountered _before_ the code is run, so it''s no use trying to capture
those by setting it in the script itself. Use php.ini / httpd.conf /
..htaccess files to set that configuration.

You can also do a simple check from the command line if you have that
available:

php -l /the/file/to/check

(which is one of the first tools I set/create whenever using a new
(version of) an editor).

PHP 4即将结束，甚至在

长之前都不会添加安全更新...

PHP 4 is end of life, not even security updates will be added before

我在php文档中看到一些例子使用5.3，考虑到

输了！

latest stable release is 5.2 I can see how there might be a lot of hair

是的，需要考虑的事项，没有''单独''的文件，所以

记住'' ''注释很重要:)

Yup, something to consider, there''s no ''seperate'' documentation, so
keeping in mind the ''since'' notes are important :)

无法帮助你。

Couldn''t help you there.

是否使用了标准的include_path？

Is there a standard include_path being used?

是的，它被欺骗性地命名为''include_path''，并且可以设置在你的代码或配置的任何地方，保持记住目前工作的是什么
目录。

Yes, it''s deceptively named ''include_path'', and can be set anywhere in
your code or configuration, keep in mind what the current working
directory is though.

是否有任何包含图书馆的标准扩展，通常我会

喜欢它们只能*由父脚本*看到。

Are there any standard extensions for included libararies, generally I''d
like them to be seen *only* by the parent script.

只要在PHP脚本中包含库/函数/类，

它们的定义将可以从代码中的任何位置使用（不是实例

对象当然是那些服从范围）。命名空间将以PHP6到达我相信。
相信。

.... spamrun完成

As soon as you include libraries/functions/classes in you PHP script,
their definitions will be usable from anywhere in the code (not instances
of objects of course, those obey scope). Namespaces will arrive in PHP6 I
believe.

好​​的，我会找到一个检查PHP.ini文件，因为我发现脚本

默默地失败了。

OK, I''ll find a check the PHP.ini file as I''m finding that the scripts
silently fail.

好​​的。我正在研究的那个盒子在今年被初始化了。我期待5

的东西。这必须只是我的网站主机（RackSpace）的偏好。

OK. The box I''m working on was initialized in this year. I expected 5
something. This must just be a preference with my web host (RackSpace).

many "functions"! I''m a bit overwhelmed!
