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.

DATE_DEFAULT_TIMEZONE_GET(3)						 1					      DATE_DEFAULT_TIMEZONE_GET(3)

date_default_timezone_get - Gets the default timezone used by all date/time functions in a script

SYNOPSIS

       string date_default_timezone_get (void  )

DESCRIPTION

	In order of preference, this function returns the default timezone by:

	      o Reading the timezone set using the date_default_timezone_set(3) function (if any)

	      o Prior to PHP 5.4.0
		only: Reading the $TZ environment variable (if non empty)

	      o Reading the value of the date.timezone ini option (if set)

	      o Prior to PHP 5.4.0
		only:  Querying the host operating system (if supported and allowed by the OS). This uses an algorithm that has to guess the time-
		zone. This is by no means going to work correctly for every situation. A warning is shown when this stage is reached. Do not  rely
		on it to be guessed correctly, and set date.timezone to the correct timezone instead.

	If none of the above succeed, date_default_timezone_get will return a default timezone of UTC.

RETURN VALUES

	Returns a string.

EXAMPLES

       Example #1

	      Getting the default timezone

	      <?php
	      date_default_timezone_set('Europe/London');

	      if (date_default_timezone_get()) {
		  echo 'date_default_timezone_set: ' . date_default_timezone_get() . '<br />';
	      }

	      if (ini_get('date.timezone')) {
		  echo 'date.timezone: ' . ini_get('date.timezone');
	      }

	      ?>

	      The above example will output something similar to:

	      date_default_timezone_set: Europe/London
	      date.timezone: Europe/London

       Example #2

	      Getting the abbreviation of a timezone

	      <?php
	      date_default_timezone_set('America/Los_Angeles');
	      echo date_default_timezone_get() . ' => ' . date('e') . ' => ' . date('T');
	      ?>

	      The above example will output:

	      America/Los_Angeles => America/Los_Angeles => PST
