|

|
|
* Converts a PHP array into an XML string.
|
|
* The XML output is optimized for readability since associative keys are used as tag names.
|
|
* This also means that only alphanumeric characters are allowed in the tag names AND only keys NOT starting with numbers (so watch your usage of keys!). However there are options you can set to avoid this problem.
|
|
* Numeric keys are stored with the default tag name "numIndex" but can be overridden to other formats)
|
|
* The function handles input values from the PHP array in a binary-safe way; All characters below 32 (except 9,10,13) will trigger the content to be converted to a base64-string
|
|
* The PHP variable type of the data IS preserved as long as the types are strings, arrays, integers and booleans. Strings are the default type unless the "type" attribute is set.
|
|
* The output XML has been tested with the PHP XML-parser and parses OK under all tested circumstances with 4.x versions. However, with PHP5 there seems to be the need to add an XML prologue a la <?xml version="1.0" encoding="[charset]" standalone="yes" ?> - otherwise UTF-8 is assumed! Unfortunately, many times the output from this function is used without adding that prologue meaning that non-ASCII characters will break the parsing!! This suchs of course! Effectively it means that the prologue should always be prepended setting the right characterset, alternatively the system should always run as utf-8!
|
|
* However using MSIE to read the XML output didn't always go well: One reason could be that the character encoding is not observed in the PHP data. The other reason may be if the tag-names are invalid in the eyes of MSIE. Also using the namespace feature will make MSIE break parsing. There might be more reasons...

(Notice: NO username/password + NO fragment)

CLIENT____:
|
|
REMOTE_ADDR = (client IP)
|
|
REMOTE_HOST = (client host)
|
|
HTTP_USER_AGENT = (client user agent)
|
|
HTTP_ACCEPT_LANGUAGE = (client accept language)
|
|
|
|
SERVER____:
|
|
SCRIPT_FILENAME = Absolute filename of script (Differs between windows/unix). On windows 'C:\\blabla\\blabl\\' will be converted to 'C:/blabla/blabl/'
|
|
|
|
Special extras:
|
|
TYPO3_HOST_ONLY = [host] = 192.168.1.4
|
|
TYPO3_PORT = [port] = 8080 (blank if 80, taken from host value)
|
|
TYPO3_REQUEST_HOST = [scheme]://[host][:[port]]
|
|
TYPO3_REQUEST_URL = [scheme]://[host][:[port]][path]?[query] (scheme will by default be "http" until we can detect something different)
|
|
TYPO3_REQUEST_SCRIPT = [scheme]://[host][:[port]][path_script]
|
|
TYPO3_REQUEST_DIR = [scheme]://[host][:[port]][path_dir]
|
|
TYPO3_SITE_URL = [scheme]://[host][:[port]][path_dir] of the TYPO3 website frontend
|
|
TYPO3_SITE_PATH = [path_dir] of the TYPO3 website frontend
|
|
TYPO3_SITE_SCRIPT = [script / Speaking URL] of the TYPO3 website
|
|
TYPO3_DOCUMENT_ROOT = Absolute path of root of documents: TYPO3_DOCUMENT_ROOT.SCRIPT_NAME = SCRIPT_FILENAME (typically)
|
|
TYPO3_SSL = Returns TRUE if this session uses SSL/TLS (https)
|
|
TYPO3_PROXY = Returns TRUE if this session runs over a well known proxy
|
|
|
|
Notice: [fragment] is apparently NEVER available to the script!
|
|
|
|
Testing suggestions:
|
|
- Output all the values.
|
|
- In the script, make a link to the script it self, maybe add some parameters and click the link a few times so HTTP_REFERER is seen
|
|
- ALSO TRY the script from the ROOT of a site (like 'http://www.mytest.com/' and not 'http://www.mytest.com/test/' !!)
