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.

       the system settings or the $TZ environment variable. See also date_default_timezone_set(3)

EXAMPLES

       Example #1

	      date_sunset(3) example

	      <?php

	      /* calculate the sunset time for Lisbon, Portugal

	      Longitude: 9 West
	      Zenith ~= 90

	      echo date("D M d Y"). ', sunset time : ' .date_sunset(time(), SUNFUNCS_RET_STRING, 38.4, -9, 90, 1);

	      ?>

	      The above example will output something similar to:

	      Mon Dec 20 2004, sunset time : 18:13
