mysqlnd_qc_set_storage_handler - Change current storage handler

SYNOPSIS

       bool mysqlnd_qc_set_storage_handler (string  $handler)

DESCRIPTION

	Sets  the  storage handler used by the query cache. A list of available storage handler can be obtained from mysqlnd_qc_get_available_han-
       dlers(3). Which storage are available depends on the compile time configuration of the query cache plugin. The default storage  handler	is
       always available. All other storage handler must be enabled explicitly when building the extension.

PARAMETERS

	      o $handler
		-  Handler  can  be  of  type  string  representing  the  name	of a built-in storage handler or an object of type mysqlnd_qc_han-
		dler_default. The names of the built-in storage handler are default, APC, MEMCACHE, sqlite.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

	If changing the storage handler fails a catchable fatal error will be thrown. The query cache cannot operate if the previous storage  han-
       dler has been shutdown but no new storage handler has been installed.

EXAMPLES

       Example #1

	      mysqlnd_qc_set_storage_handler(3) example

	       The example shows the output from the built-in default storage handler. Other storage handler may report different data.

	      <?php
	      var_dump(mysqlnd_qc_set_storage_handler("memcache"));

	      if (true === mysqlnd_qc_set_storage_handler("default"))
		printf("Default storage handler activated");

	      /* Catchable fatal error */
	      var_dump(mysqlnd_qc_set_storage_handler("unknown"));
	      ?>

	      The above examples will output:

	      bool(true)
	      Default storage handler activated
	      Catchable fatal error: mysqlnd_qc_set_storage_handler(): Unknown handler 'unknown' in (file) on line (line)

xml_set_external_entity_ref_handler - Set up external entity reference handler

SYNOPSIS

       bool xml_set_external_entity_ref_handler (resource  $parser, callable  $handler)

DESCRIPTION

	Sets the external entity reference handler function for the XML parser $parser.

PARAMETERS

	      o $parser
		- A reference to the XML parser to set up external entity reference handler function.

	      o $handler
		-$handler  is  a  string  containing the name of a function that must exist when xml_parse(3) is called for $parser.  The function
		named by $handler must accept five parameters, and should return an integer value.If the value returned from the handler is  FALSE
		(which	it  will  be  if  no  value  is  returned),  the  XML  parser  will  stop  parsing  and  xml_get_error_code(3) will return
		XML_ERROR_EXTERNAL_ENTITY_HANDLING.
		 handler (resource  $parser, string  $open_entity_names, string  $base, string	$system_id, string  $public_id)

		     o $parser
		       - The first parameter, parser, is a reference to the XML parser calling the handler.

		     o $open_entity_names
		       - The second parameter, $open_entity_names, is a space-separated list of the names of the entities that are  open  for  the
		       parse of this entity (including the name of the referenced entity).

		     o $base
		       -  This	is  the base for resolving the system identifier ($system_id) of the external entity.Currently this parameter will
		       always be set to an empty string.

		     o $system_id
		       - The fourth parameter, $system_id, is the system identifier as specified in the entity declaration.

		     o $public_id
		       - The fifth parameter, $public_id, is the public identifier as specified in the entity declaration, or an empty	string	if
		       none was specified; the whitespace in the public identifier will have been normalized as required by the XML spec.

	       If a handler function is set to an empty string, or FALSE, the handler in question is disabled.

	      Note

		     Instead of a function name, an array containing an object reference and a method name can also be supplied.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.
