str_word_count - Return information about words used in a string

SYNOPSIS

       mixed str_word_count (string  $string, [int  $format], [string  $charlist])

DESCRIPTION

	Counts the number of words inside $string. If the optional $format is not specified, then the return value will be an integer representing
       the number of words found. In the event the $format is specified, the return value will be an array, content of which is dependent  on  the
       $format. The possible value for the $format and the resultant outputs are listed below.

	For the purpose of this function, 'word' is defined as a locale dependent string containing alphabetic characters, which also may contain,
       but not start with "'" and "-" characters.

PARAMETERS

	      o $string
		- The string

	      o $format
		- Specify the return value of this function. The current supported values are:

		     o 0 - returns the number of words found

		     o 1 - returns an array containing all the words found inside the $string

		     o 2 - returns an associative array, where the key is the numeric position of the word inside the $string and the value is the
		     actual word itself

	      o $charlist
		- A list of additional characters which will be considered as 'word'

RETURN VALUES

	Returns an array or an integer, depending on the $format chosen.

EXAMPLES

       Example #1

	      A str_word_count(3) example

	      <?php

	      $str = "Hello fri3nd, you're
		     looking	      good today!";

	      print_r(str_word_count($str, 1));
	      print_r(str_word_count($str, 2));
	      print_r(str_word_count($str, 1, 'aaac3'));

	      echo str_word_count($str);

	      ?>

	      The above example will output:

	      Array
	      (

ini_get_all - Gets all configuration options

SYNOPSIS

       array ini_get_all ([string  $extension], [bool  $details = true])

DESCRIPTION

	Returns all the registered configuration options.

PARAMETERS

	      o $extension
		- An optional extension name. If set, the function return only options specific for that extension.

	      o $details
		- Retrieve details settings or only the current value for each setting. Default is TRUE (retrieve details).

RETURN VALUES

	Returns an associative array with directive name as the array key.

	When  $details	is TRUE (default) the array will contain global_value (set in php.ini), local_value (perhaps set with ini_set(3) or .htac-
       cess), and access (the access level).

	When $details is FALSE the value will be the current value of the option.

	See the manual section for information on what access levels mean.

       Note

	       It's possible for a directive to have multiple access levels, which is why access shows the appropriate bitmask values.

       Example #2

	      Disabling $details

	      print_r(ini_get_all(null, false)); // Added in PHP 5.3.0
	      ?>

	      The above example will output something similar to:

	      Array
	      (
		  [pcre.backtrack_limit] => 100000
		  [pcre.recursion_limit] => 100000
	      )
