parse_ini_string - Parse a configuration string

SYNOPSIS

       array parse_ini_string (string  $ini, [bool  $process_sections = false], [int  $scanner_mode = INI_SCANNER_NORMAL])

DESCRIPTION

       parse_ini_string(3) returns the settings in string $ini in an associative array.

	The structure of the ini string is the same as the php.ini's.

PARAMETERS

	      o $ini
		- The contents of the ini file being parsed.

	      o $process_sections
		-  By  setting	the  $process_sections	parameter  to  TRUE, you get a multidimensional array, with the section names and settings
		included. The default for $process_sections is FALSE

	      o $scanner_mode
		- Can either be INI_SCANNER_NORMAL (default) or INI_SCANNER_RAW. If INI_SCANNER_RAW is supplied, then option values  will  not	be
		parsed.   As  of  PHP 5.6.1 can also be specified as INI_SCANNER_TYPED. In this mode boolean, null and integer types are preserved
		when possible. String values "true", "on" and "yes" are converted to TRUE.  "false", "off", "no" and "none" are considered  FALSE.
		"null" is converted to NULL in typed mode. Also, all numeric strings are converted to integer type if it is possible.

RETURN VALUES

	The settings are returned as an associative array on success, and FALSE on failure.

NOTES

       Note

	       There  are  reserved  words which must not be used as keys for ini files. These include: null, yes, no, true, false, on, off, none.
	      Values null, off, no and false result in "", and values on, yes and true result in "1", unless INI_SCANNER_TYPED mode is used. Char-
	      acters ?{}|&~![()^" must not be used anywhere in the key and have a special meaning in the value.

ini_get - Gets the value of a configuration option

SYNOPSIS

       string ini_get (string  $varname)

DESCRIPTION

	Returns the value of the configuration option on success.

PARAMETERS

	      o $varname
		- The configuration option name.

RETURN VALUES

	Returns  the value of the configuration option as a string on success, or an empty string for null values. Returns FALSE if the configura-
       tion option doesn't exist.

EXAMPLES

       Example #1

	      A few ini_get(3) examples

	      <?php
	      /*
	      Our php.ini contains the following settings:

	      display_errors = On
	      register_globals = Off
	      post_max_size = 8M
	      */

	      echo 'display_errors = ' . ini_get('display_errors') . "
";
	      echo 'register_globals = ' . ini_get('register_globals') . "
";
	      echo 'post_max_size = ' . ini_get('post_max_size') . "
";
	      echo 'post_max_size+1 = ' . (ini_get('post_max_size')+1) . "
";
	      echo 'post_max_size in bytes = ' . return_bytes(ini_get('post_max_size'));

	      function return_bytes($val) {
		  $val = trim($val);
		  $last = strtolower($val[strlen($val)-1]);
		  switch($last) {
		      // The 'G' modifier is available since PHP 5.1.0
		      case 'g':
			  $val *= 1024;
		      case 'm':
			  $val *= 1024;
		      case 'k':
			  $val *= 1024;
		  }

		  return $val;
	      }

	      ?>

	      The above example will output something similar to:

	      display_errors = 1
	      register_globals = 0
	      post_max_size = 8M
	      post_max_size+1 = 9
	      post_max_size in bytes = 8388608

NOTES

       Note

	      When querying boolean values

	       A boolean ini value of off will be returned as an empty string or "0" while a boolean ini value of on will be returned as "1".  The
	      function can also return the literal string of INI value.

       Note

	      When querying memory size values

	       Many  ini  memory  size	values, such as upload_max_filesize, are stored in the php.ini file in shorthand notation. ini_get(3) will
	      return the exact string stored in the php.ini file and NOT its integer equivalent. Attempting normal arithmetic functions  on  these
	      values will not have otherwise expected results. The example above shows one way to convert shorthand notation into bytes, much like
	      how the PHP source does it.
