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.

EXAMPLES

       Example #1

	      ini_get_all(3) examples

	      <?php
	      print_r(ini_get_all("pcre"));
	      print_r(ini_get_all());
	      ?>

	      The above example will output something similar to:

	      Array
	      (
		  [pcre.backtrack_limit] => Array
		      (
			  [global_value] => 100000
			  [local_value] => 100000
			  [access] => 7
		      )

		  [pcre.recursion_limit] => Array
		      (
			  [global_value] => 100000
			  [local_value] => 100000
			  [access] => 7
		      )

	      )
	      Array
	      (
		  [allow_call_time_pass_reference] => Array
		      (
			  [global_value] => 0
			  [local_value] => 0
			  [access] => 6
		      )

		  [allow_url_fopen] => Array
		      (
			  [global_value] => 1
			  [local_value] => 1
			  [access] => 4
		      )

		  ...

	      )

       Example #2

	      Disabling $details

	      <?php
	      print_r(ini_get_all("pcre", false)); // Added in PHP 5.3.0
	      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
	      )
	      Array
	      (
		  [allow_call_time_pass_reference] => 0
		  [allow_url_fopen] => 1
		  ...
	      )

PRINT_R(3)								 1								PRINT_R(3)

print_r - Prints human-readable information about a variable

SYNOPSIS

       mixed print_r (mixed  $expression, [bool  $return = false])

DESCRIPTION

       print_r(3) displays information about a variable in a way that's readable by humans.

       print_r(3),  var_dump(3) and var_export(3) will also show protected and private properties of objects with PHP 5. Static class members will
       not be shown.

PARAMETERS

	      o $expression
		- The expression to be printed.

	      o $return
		- If you would like to capture the output of print_r(3), use the $return parameter. When this parameter is set to TRUE, print_r(3)
		will return the information rather than print it.

RETURN VALUES

	If  given a string, integer or float, the value itself will be printed. If given an array, values will be presented in a format that shows
       keys and elements. Similar notation is used for objects.

	When the $return parameter is TRUE, this function will return a string. Otherwise, the return value is TRUE.

NOTES

       Note

	      When the $return parameter is used, this function uses internal output buffering so it cannot be used inside an ob_start(3) callback
	      function.

EXAMPLES

       Example #1

	      print_r(3) example

	      <pre>
	      <?php
	      $a = array ('a' => 'apple', 'b' => 'banana', 'c' => array ('x', 'y', 'z'));
	      print_r ($a);
	      ?>
	      </pre>

	      The above example will output:

	      <pre>
	      Array
	      (
		  [a] => apple
		  [b] => banana
		  [c] => Array
		      (
			  [0] => x
			  [1] => y
			  [2] => z
		      )
	      )
	      </pre>

       Example #2

	      $return parameter example

	      <?php
	      $b = array ('m' => 'monkey', 'foo' => 'bar', 'x' => array ('x', 'y', 'z'));
	      $results = print_r($b, true); // $results now contains output from print_r
	      ?>
