error_reporting - Sets which PHP errors are reported

SYNOPSIS

       int error_reporting ([int  $level])

DESCRIPTION

	The  error_reporting(3)  function  sets  the error_reporting directive at runtime. PHP has many levels of errors, using this function sets
       that level for the duration (runtime) of your script. If the optional $level is not set, error_reporting(3) will just  return  the  current
       error reporting level.

PARAMETERS

	      o $level
		- The new error_reporting level. It takes on either a bitmask, or named constants. Using named constants is strongly encouraged to
		ensure compatibility for future versions. As error levels are added, the range of integers increases, so older integer-based error
		levels	will not always behave as expected.  The available error level constants and the actual meanings of these error levels are
		described in the predefined constants.

RETURN VALUES

	Returns the old error_reporting level or the current level if no $level parameter is given.

EXAMPLES

       Example #1

	      error_reporting(3) examples

	      <?php

	      // Turn off all error reporting
	      error_reporting(0);

	      // Report simple running errors
	      error_reporting(E_ERROR | E_WARNING | E_PARSE);

	      // Reporting E_NOTICE can be good too (to report uninitialized
	      // variables or catch variable name misspellings ...)
	      error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE);

	      // Report all errors except E_NOTICE
	      error_reporting(E_ALL & ~E_NOTICE);

	      // Report all PHP errors (see changelog)
	      error_reporting(E_ALL);

	      // Report all PHP errors
	      error_reporting(-1);

	      // Same as error_reporting(E_ALL);
	      ini_set('error_reporting', E_ALL);

	      ?>

NOTES

       Warning

	       Most of E_STRICT errors are evaluated at the compile time thus such errors are not reported in the file	where  error_reporting	is
	      enhanced to include E_STRICT errors (and vice versa).

       Tip

	       Passing	in  the  value -1 will show every possible error, even when new levels and constants are added in future PHP versions. The
	      E_ALL constant also behaves this way as of PHP 5.4.
