The functions listed here enable you to change the settings of locale parameters for your PHP scripts.

bcscale(scale) | clearstatcache() | magic_quotes_runtime(on/off) | setlocale(category, locale) | sleep(seconds) | usleep(microseconds)

bcscale(scale)
Sets the default scale parameter for all arbitrary precision mathematics functions that do not explicitly receive a scale parameter when called up. The number passed as the argument defines the number of digits after the decimal point.
Example	<?  bcscale(5);  ?>

clearstatcache()
PHP keeps in its cache the results of a call to the stat function, so that a subsequent call to this function will use the data in cache to avoid another expensive run. However, if you make use of a frequently updated file, this behaviour could be a source of errors. To force a rerun of stat, call up clearstatcache to first delete the old results in cache.
Example	<?  clearstatcache();  ?>
Top

magic_quotes_runtime(on/off)
Defines the setting of the magic_quotes_runtime configuration parameter. When this parameter is activated, most of the functions returning external data will have their quotes escaped with a backslash.
Example	<?  magic_quotes_runtime(on);  ?>
Top

register_shutdown_function (function)
Registers the function passed as the argument to be executed after complete processing of the script.
Example	<?   function shutdown()   {       print("<!--End of script -->\n");   }   register_shutdown_function("shutdown"); ?>
Top

setlocale(category, locale)
Sets the local information used by your PHP scripts. The category argument defines the functions affected by the locale setting. Here are the category codes available:
Category	Description
LC_ALL	Affects all the function categories listed below.
LC_COLLATE	Affects the string comparisons.
LC_CTYPE	Affects the character conversion and classification operations.
LC_MONETARY	Affects the currency formatting information.
LC_NUMERIC	Affects the decimal separator.
LC_TIME	Affects the time and date formatting information.
You can also use zero to obtain all the current parameters. If no value is specified for the category argument, the corresponding values will be set using the environment variables.
Example :	<?   print("German: ");   print(setlocale(LC_TIME, "de")); ?>
Top

sleep(seconds)
Delays the script execution for the number of seconds passed as the argument.
Example	<?   sleep(5); ?>
Top

usleep(microseconds)
Delays the script execution for the number of microseconds passed as the argument.
Example	<?   usleep(80); ?>
