apc_inc - Increase a stored number

SYNOPSIS

       int apc_inc (string  $key, [int	$step = 1], [bool  &$success])

DESCRIPTION

	Increases a stored number.

PARAMETERS

	      o $key
		- The key of the value being increased.

	      o $step
		- The step, or value to increase.

	      o $success
		- Optionally pass the success or fail boolean value to this referenced variable.

RETURN VALUES

	Returns the current value of $key's value on success, or FALSE on failure

EXAMPLES

       Example #1

	      apc_inc(3) example

	      <?php
	      echo "Let's do something with success", PHP_EOL;

	      apc_store('anumber', 42);

	      echo apc_fetch('anumber'), PHP_EOL;

	      echo apc_inc('anumber'), PHP_EOL;
	      echo apc_inc('anumber', 10), PHP_EOL;
	      echo apc_inc('anumber', 10, $success), PHP_EOL;

	      var_dump($success);

	      echo "Now, let's fail", PHP_EOL, PHP_EOL;

	      apc_store('astring', 'foo');

	      $ret = apc_inc('astring', 1, $fail);

	      var_dump($ret);
	      var_dump($fail);
	      ?>

	      The above example will output something similar to:

	      42
