runkit_function_redefine - Replace a function definition with a new implementation

SYNOPSIS

       bool runkit_function_redefine (string  $funcname, string  $arglist, string  $code)

DESCRIPTION

       Note

	      By  default, only userspace functions may be removed, renamed, or modified. In order to override internal functions, you must enable
	      the runkit.internal_override setting in php.ini.

PARAMETERS

	      o $funcname
		- Name of function to redefine

	      o $arglist
		- New list of arguments to be accepted by function

	      o $code
		- New code implementation

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      A runkit_function_redefine(3) example

	      <?php
	      function testme() {
		echo "Original Testme Implementation
";
	      }
	      testme();
	      runkit_function_redefine('testme','','echo "New Testme Implementation
";');
	      testme();
	      ?>

	      The above example will output:

	      Original Testme Implementation
	      New Testme Implementation

DESCRIPTION

       Warning

	      This  function is EXPERIMENTAL. The behaviour of this function, its name, and surrounding documentation may change without notice in
	      a future release of PHP. This function should be used at your own risk.

PARAMETERS

		- The class to which this method will be added

	      o $methodname
		- The name of the method to add

	      o $args
		- Comma-delimited list of arguments for the newly-created method

	      o $code
		- The code to be evaluated when $methodname is called

	      o $flags
		- The type of method to create, can be RUNKIT_ACC_PUBLIC, RUNKIT_ACC_PROTECTED or RUNKIT_ACC_PRIVATE

	      Note

		      This parameter is only used as of PHP 5, because, prior to this, all methods were public.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      runkit_method_add(3) example

	      <?php
	      class Example {
		  function foo() {
		      echo "foo!
";
		  }
	      }

	      // create an Example object
	      $e = new Example();

	      // Add a new public method
	      runkit_method_add(
		  'Example',
		  'add',
		  '$num1, $num2',
		  'return $num1 + $num2;',
		  RUNKIT_ACC_PUBLIC
	      );

	      // add 12 + 4

	      ?>

	      The above example will output:
