RUNKIT_METHOD_REDEFINE(3)						 1						 RUNKIT_METHOD_REDEFINE(3)

runkit_method_redefine - Dynamically changes the code of the given method

SYNOPSIS

       bool runkit_method_redefine (string  $classname, string	$methodname, string  $args, string  $code, [int  $flags = RUNKIT_ACC_PUBLIC])

DESCRIPTION

       Note

	      This function cannot be used to manipulate the currently running (or chained) method.

       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

	      o $classname
		- The class in which to redefine the method

	      o $methodname
		- The name of the method to redefine

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

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

	      o $flags
		- The redefined method 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_redefine(3) example

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

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

	      // output Example::foo() (before redefine)
	      echo "Before: " . $e->foo();

	      // Redefine the 'foo' method
	      runkit_method_redefine(
		  'Example',
		  'foo',
		  '',
		  'return "bar!
";',
		  RUNKIT_ACC_PUBLIC
	      );

	      // output Example::foo() (after redefine)
	      echo "After: " . $e->foo();
	      ?>

	      The above example will output:

	      Before: foo!
	      After: bar!

PRINT(3)								 1								  PRINT(3)

print - Output a string

SYNOPSIS

       int print (string  $arg)

DESCRIPTION

	Outputs $arg.

       print is not actually a real function (it is a language construct) so you are not required to use parentheses with its argument list.

PARAMETERS

	      o $arg
		- The input data.

RETURN VALUES

	Returns 1, always.

EXAMPLES

       Example #1

	      print examples

	      <?php
	      print("Hello World");

	      print "print() also works without parentheses.";

	      print "This spans
	      multiple lines. The newlines will be
	      output as well";

	      print "This spans
multiple lines. The newlines will be
output as well.";

	      print "escaping characters is done "Like this".";

	      // You can use variables inside a print statement
	      $foo = "foobar";
	      $bar = "barbaz";

	      print "foo is $foo"; // foo is foobar

	      // You can also use arrays
	      $bar = array("value" => "foo");

	      print "this is {$bar['value']} !"; // this is foo !

	      // Using single quotes will print the variable name, not the value
	      print 'foo is $foo'; // foo is $foo

	      // If you are not using any other characters, you can just print variables
	      print $foo;	   // foobar

	      print <<<END
	      This uses the "here document" syntax to output
	      multiple lines with $variable interpolation. Note
	      that the here document terminator must appear on a
	      line with just a semicolon no extra whitespace!
	      END;
	      ?>

NOTES

       Note

	      Because this is a language construct and not a function, it cannot be called using variable functions.
