时间：2020-12-01 08:55:12

1.静态变量日期

define( 'MINUTE_IN_SECONDS', 60 );

define( 'HOUR_IN_SECONDS',   60 * MINUTE_IN_SECONDS );

define( 'DAY_IN_SECONDS',    24 * HOUR_IN_SECONDS   );

define( 'WEEK_IN_SECONDS',    7 * DAY_IN_SECONDS    );

define( 'YEAR_IN_SECONDS',  365 * DAY_IN_SECONDS    );

2.禁止开启magic quotes

@ini_set( 'magic_quotes_runtime', 0 );

@ini_set( 'magic_quotes_sybase',  0 );

3.设置时区

date_default_timezone_set('Asia/Hong_Kong');

4.检查是否在维护

function wp_maintenance() {

    if ( !file_exists( ABSPATH . '.maintenance' ) || defined( 'WP_INSTALLING' ) )

        return;

    global $upgrading;

    include( ABSPATH . '.maintenance' );

    // If the $upgrading timestamp is older than 10 minutes, don't die.

    if ( ( time() - $upgrading ) >= 600 )

        return;

    if ( file_exists( WP_CONTENT_DIR . '/maintenance.php' ) ) {

        require_once( WP_CONTENT_DIR . '/maintenance.php' );

        die();

    }

    wp_load_translations_early();

    $protocol = $_SERVER["SERVER_PROTOCOL"];

    if ( 'HTTP/1.1' != $protocol && 'HTTP/1.0' != $protocol )

        $protocol = 'HTTP/1.0';

    header( "$protocol 503 Service Unavailable", true, 503 );

    header( 'Content-Type: text/html; charset=utf-8' );

    header( 'Retry-After: 600' );

?>

    <!DOCTYPE html>

    <html xmlns="http://www.w3.org/1999/xhtml"<?php if ( is_rtl() ) echo ' dir="rtl"'; ?>>

    <head>

    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

        <title><?php _e( 'Maintenance' ); ?></title>

    </head>

    <body>

        <h1><?php _e( 'Briefly unavailable for scheduled maintenance. Check back in a minute.' ); ?></h1>

    </body>

    </html>

<?php

    die();

}

5.检查是否开启调试模式

function wp_debug_mode() {

    if ( WP_DEBUG ) {

        error_reporting( E_ALL );

        if ( WP_DEBUG_DISPLAY )

            ini_set( 'display_errors', 1 );

        elseif ( null !== WP_DEBUG_DISPLAY )

            ini_set( 'display_errors', 0 );

        if ( WP_DEBUG_LOG ) {

            ini_set( 'log_errors', 1 );

            ini_set( 'error_log', WP_CONTENT_DIR . '/debug.log' );

        }

    } else {

        error_reporting( E_CORE_ERROR | E_CORE_WARNING | E_COMPILE_ERROR | E_ERROR | E_WARNING | E_PARSE | E_USER_ERROR | E_USER_WARNING | E_RECOVERABLE_ERROR );

    }

    if ( defined( 'XMLRPC_REQUEST' ) )

        ini_set( 'display_errors', 0 );

}
