XSLT_SET_SCHEME_HANDLERS(3)						 1					       XSLT_SET_SCHEME_HANDLERS(3)

xslt_set_scheme_handlers - Set the scheme handlers for theXSLTprocessor

SYNOPSIS

       void xslt_set_scheme_handlers (resource	$xh, array  $handlers)

DESCRIPTION

	Registers the scheme handlers (XPath handlers) for the document.

PARAMETERS

	      o $
		xh -The XSLT processor link identifier, created with xslt_create(3).

	      o $handlers
		- An array with the following keys: "get_all", "open", "get", "put", and "close".  Every entry must be a function name or an array
		in the following format: array($obj, "method").  Note that the given array does not need to contain all of  the  different  scheme
		handler  elements  (although it can), but it only needs to conform to the "handler" => "function" format described above.  Each of
		the individual scheme handler functions called are in the formats below:

	      string   get_all(resource processor, string scheme, string rest)
	      resource open(resource processor, string scheme, string rest)
	      int      get(resource processor, resource fp, string &data)
	      int      put(resource processor, resource fp, string data)
	      void     close(resource processor, resource fp)

RETURN VALUES

	No value is returned.

EXAMPLES

       Example #1

	      xslt_set_scheme_handlers(3) example

	       For example, here is an implementation of the "file_exists()" PHP function.

	      <?php

	      // Definition of the handler
	      function mySchemeHandler($processor, $scheme, $rest)
	      {
		  $rest = substr($rest,1);    // to remove the first / automatically added by the engine
		  if ($scheme == 'file_exists') {
		      // result is embedded in a small xml string
		      return '<?xml version="1.0" encoding="UTF-8"?><root>' . (file_exists($rest) ? 'true' : 'false') . '</root>';
		  }
	      }

	      $SchemeHandlerArray = array('get_all' => 'mySchemeHandler');

	      // Start the engine
	      $params = array();
	      $xh = xslt_create();

	      xslt_set_scheme_handlers($xh, $SchemeHandlerArray);

	      $result = xslt_process($xh, "myFile.xml", "myFile.xsl", NULL, array(), $params);
	      xslt_free($xh);

	      echo $result;

	      ?>

	       Then, inside the stylesheet, you can test whether a certain file exists with:

	      <xsl:if test="document('file_exists:anotherXMLfile.xml')/root='true'">
	       <!-- The file exist -->
	      </xsl:if>

iterator_to_array - Copy the iterator into an array

SYNOPSIS

       array iterator_to_array (Traversable  $iterator, [bool  $use_keys = true])

DESCRIPTION

	Copy the elements of an iterator into an array.

PARAMETERS

	      o $iterator
		- The iterator being copied.

	      o $use_keys
		- Whether to use the iterator element keys as index.  In PHP 5.5 and later, if a key is an array or object, a warning will be gen-
		erated.  NULL keys will be converted to an empty string, double keys will be truncated to their integer counterpart, resource keys
		will generate a warning and be converted to their resource ID, and boolean keys will be converted to integers.

RETURN VALUES

	An array containing the elements of the $iterator.

EXAMPLES

       Example #1

	      iterator_to_array(3) example

	      <?php
	      $iterator = new ArrayIterator(array('recipe'=>'pancakes', 'egg', 'milk', 'flour'));
	      var_dump(iterator_to_array($iterator, true));

		[0]=>
		string(3) "egg"
		[1]=>
