[PHP] syntax error in class

[Dasn]

Hello guys, I encountered a syntax error, and cannot figure out the  
reason, for example:

==  CODE  ==
1:'str1'.'str2');
3:?>
===
Works fine, but when I try to put it into a class, say:

==  CODE  ==
1:'str1'.'str2');
5:}
6:?>
== OUTPUT ==
Parse error: syntax error, unexpected '.', expecting ')' in C:\Documents  
and Settings\Administrator\Local Settings\Temp\VI42E5.tmp on line 4
PHP Parse error:  syntax error, unexpected '.', expecting ')' in  
C:\Documents and Settings\Administrator\Local Settings\Temp\VI42E5.tmp on  
line 4



I got the syntax error. Why?

My php version:

D:\>php -version
PHP 5.3.1 (cli) (built: Nov 19 2009 10:17:43)
Copyright (c) 1997-2009 The PHP Group

Thanks in advance.

[PHP] array conversion

[Dasn]

Hi guys. How to convert an array like:

Array
(
[0] => key1
[1] => value1
[2] => key2
[3] => value2
)

to


Array
(
[key1] => value1
[key2] => value2
)

Is there a built-in function to do this?
Please Cc me. :)
Thank you in advance.

[PHP] How to get the 'return type' of a function?

[Dasn]

Hello guys, I try to use 'ReflectionFunction' to retrieve the info of a  
function.

For example:

=== output ==

Function [  function strstr ] {

  - Parameters [3] {
Parameter #0 [  $haystack ]
Parameter #1 [  $needle ]
Parameter #2 [  $part ]
  }
}

The problem is there's no 'return type' (i.e. 'string' in this example)
info about the function.

Could you tell me how to retrieve the 'return type'?
Thanks.

As PHP is loosely typed, the only real way around this is to specify a
return type in a PHPDoc block, then parse that using reflection to get
the @return parameter.

another option is to use something like haXe which is an ECMA style
typed language that compiles to multiple targets, one of which is PHP.



Thanks Nathan for your comment. But I think the PHPDoc stuff is only for
user defined functions, right? The Reflection::getDocComment() has no idea
about the built-in functions.

[PHP] SimpleXML: convert xml to text

[Dasn]

Hello, I want to convert some xml stuff to simple string using php, say:

 left center1okcenter2right 
XML;

$xml = simplexml_load_string($string);
echo $xml;
?>
The code will output "left right" while all the central stuff was lost.
How should I print it as "left center1 ok center2 right" ?

Thanks in advance, and please Cc me. :)

Can't you just call strip_tags() on the string? As you don't need to
echo any attribute values, I would have thought it would be perfect. As
XML is meant to be well-formed anyway, strip_tags shouldn't cause any
problems with broken or missing closing tags.


Thanks Ashley for your reply.
Sorry that my description was not clear enough.
Actually I don't want to just strip the tags, sometimes I also wanna  
change some elements. For another example:  
"blastrip_tagsbla". When output, I also want  
to make some change to the data depending on the tags, say, trying to  
append a pair of "()" to the "" element, printing it as "bla  
strip_tags() bla".
The problem is when I processing the nodes with SimpleXML, I couldn't get  
the right order of the data. That is :
"echo $xml->a, (string) $xml->a->function . '()'" // prints "bla bla  
strip_tags()"


Thank you anyway. Cc please.
