Answer 1

在 PHP 5.4 中，使用 E_STRICT 和 E_ALL 有什么区别。

嗯:

5.4.0   E_STRICT became part of E_ALL.
5.3.0   E_DEPRECATED and E_USER_DEPRECATED introduced.
5.2.0   E_RECOVERABLE_ERROR introduced.
5.0.0   E_STRICT introduced (not part of E_ALL).

一个例子:

<?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);

?>
