These functions enable you to access Apache internal
features—they form a high-level interface to some Apache API functions.
Consequently, these functions are available only if you have compiled PHP as an
Apache module. It's important to remember that these functions are
case-sensitive. Functions such as apache_note() make a distinction
between uppercase and lowercase variables, just like normal PHP variables.
apache_lookup_uri
class apache_lookup_uri(string URI)
Opens an Apache subrequest to look up
status information for a URI (Uniform Resource Identifier).
Returns:
Class containing a list of status information for a URI
Description:
If you have installed PHP as an Apache module, you can use this
function to get information about a URI. Just as with virtual() or an
SSI-include, the function opens an Apache subrequest; therefore, you can specify
only a local document URI as the parameter.
apache_note
mixed apache_note(string key, [string value])
Returns:
Value of the Apache note corresponding to the key specified as
the first argument; FALSE if no entry was found for the specified
key
