折腾：
【未解决】WordPress的php的log文件php-fpm.log太大
期间，去看php的错误日志：
/usr/local/php/var/log/php-fpm.log
PHP message: PHP Warning: Use of undefined constant PRC - assumed 'PRC' (this will throw an Error in a future version of PHP) in /data/wwwroot/www.crifan.com/wp-content/themes/daqianduan-d8-jquiss/comments.php on line 17" PHP message: PHP Warning: Use of undefined constant PRC - assumed 'PRC' (this will throw an Error in a future version of PHP) in /data/wwwroot/www.crifan.com/wp-content/themes/daqianduan-d8-jquiss/comments.php on line 17" PHP message: PHP Warning: Use of undefined constant PRC - assumed 'PRC' (this will throw an Error in a future version of PHP) in /data/wwwroot/www.crifan.com/wp-content/themes/daqianduan-d8-jquiss/comments.php on line 17" PHP message: PHP Warning: Use of undefined constant PRC - assumed 'PRC' (this will throw an Error in a future version of PHP) in /data/wwwroot/www.crifan.com/wp-content/themes/daqianduan-d8-jquiss/comments.php on line 17" PHP message: PHP Warning: Use of undefined constant PRC - assumed 'PRC' (this will throw an Error in a future version of PHP) in /data/wwwroot/www.crifan.com/wp-content/themes/daqianduan-d8-jquiss/comments.php on line 17" PHP message: PHP Warning: Use of undefined constant DESC - assumed 'DESC' (this will throw an Error in a future version of PHP) in /data/wwwroot/www.crifan.com/wp-content/themes/daqianduan-d8-jquiss/404.php on line 10" PHP message: PHP Warning: Use of undefined constant PRC - assumed 'PRC' (this will throw an Error in a future version of PHP) in /data/wwwroot/www.crifan.com/wp-content/themes/daqianduan-d8-jquiss/comments.php on line 17" PHP message: PHP Warning: Use of undefined constant PRC - assumed 'PRC' (this will throw an Error in a future version of PHP) in /data/wwwroot/www.crifan.com/wp-content/themes/daqianduan-d8-jquiss/comments.php on line 17" PHP message: PHP Warning: Use of undefined constant XML - assumed 'XML' (this will throw an Error in a future version of PHP) in /data/wwwroot/www.crifan.com/wp-content/plugins/wp-syntaxhighlighter/wp-syntaxhighlighter.php on line 1048" PHP message: PHP Warning: Use of undefined constant PRC - assumed 'PRC' (this will throw an Error in a future version of PHP) in /data/wwwroot/www.crifan.com/wp-content/themes/daqianduan-d8-jquiss/comments.php on line 17" PHP message: PHP Warning: Use of undefined constant PRC - assumed 'PRC' (this will throw an Error in a future version of PHP) in /data/wwwroot/www.crifan.com/wp-content/themes/daqianduan-d8-jquiss/comments.php on line 17" PHP message: PHP Warning: Use of undefined constant PRC - assumed 'PRC' (this will throw an Error in a future version of PHP) in /data/wwwroot/www.crifan.com/wp-content/themes/daqianduan-d8-jquiss/comments.php on line 17" PHP message: PHP Warning: Use of undefined constant XML - assumed 'XML' (this will throw an Error in a future version of PHP) in /data/wwwroot/www.crifan.com/wp-content/plugins/wp-syntaxhighlighter/wp-syntaxhighlighter.php on line 1048" ...
-》发现php的error的log
主要是
- themes/daqianduan-d8-jquiss/comments.php
- themes/daqianduan-d8-jquiss/404.php
- plugins/wp-syntaxhighlighter/wp-syntaxhighlighter.php
这几个地方的错误
PHP message PHP Warning Use of undefined constant PRC assumed PRC this will throw an Error in a future version of PHP themes daqianduan-d8-jquiss comments.php on line 17
$name = "Aniket"; echo name; // forgot to add $ before name -> $name
使用变量必须加上$前缀
以及：
echo $_POST[email]; -》 * echo $_POST["email"];
去改代码
下去找第一个
wp-content/themes/daqianduan-d8-jquiss/comments.php on line 17
date_default_timezone_set(PRC);
好像是要给PRC加上$？
不过
此处说是：
之后发现提示Notice: Use of undefined constant PRC – assumed ‘PRC’，原来PHP5.1.0以后date_default_timezone_set被重写,PRC无效了.改成
date_default_timezone_set("Asia/Shanghai");PHP message PHP Warning Use of undefined constant “PRC” assumed
解决Yusi1.0主题使用中存在的问题_zhouzying的博客-CSDN博客
解决方法：修改文件./yusi1.0/comments.php 将date_default_timezone_set(PRC)改为date_default_timezone_set(‘PRC’),参数类型应该为：string
参考：
bool date_default_timezone_set ( string $timezone_identifier )；
php date_default_timezone_set
date_default_timezone_set (PHP 5 >= 5.1.0, PHP 7) date_default_timezone_set — 设定用于一个脚本中所有日期时间函数的默认时区 说明 ¶ date_default_timezone_set ( string $timezone_identifier ) : bool date_default_timezone_set() 设定用于所有日期时间函数的默认时区。 Note: 自 PHP 5.1.0 起（此版本日期时间函数被重写了），如果时区不合法则每个对日期时间函数的调用都会产生一条E_NOTICE 级别的错误信息，如果使用系统设定或 TZ 环境变量则还会产生 E_STRICT 级别的信息。
date_default_timezone_set("Asia/Shanghai");
timezone
必需。规定要使用的时区，比如 "UTC" 或 "Europe/Paris"。所以此处，和
“UTC”
类似的，应该写成：
“PRC”
php timezone PRC
无意中发现 lnmp 默认的 php.ini 配置中有一行 date.timezone = PRC。PRC，People’s Republic of China，中华人民共和国，也就是日期使用中国的时区。
搜索了一下 PHP 源码，在 ext/date/lib/timezonemap.h 中看到如下代码
{ "cst", 0, 28800, "Asia/Chongqing" },
{ "cst", 0, 28800, "Asia/Chungking" },
{ "cst", 0, 28800, "Asia/Harbin" },
{ "cst", 0, 28800, "Asia/Kashgar" },
{ "cst", 0, 28800, "Asia/Macao" },
{ "cst", 0, 28800, "Asia/Macau" },
{ "cst", 0, 28800, "Asia/Shanghai" },
{ "cst", 0, 28800, "Asia/Taipei" },
{ "cst", 0, 28800, "Asia/Urumqi" },
{ "cst", 0, 28800, "PRC" },
{ "cst", 0, 28800, "ROC" },->
所以此处：
"PRC" = People‘s Republic of China = 中华人民共和国 = 日期使用中国的时区
所以可以去改代码了：
date_default_timezone_set("PRC");结果：
之前错误就消失了。
还有其他的：
PHP message: PHP Warning: Use of undefined constant DESC - assumed 'DESC' (this will throw an Error in a future version of PHP) in /data/wwwroot/www.crifan.com/wp-content/themes/daqianduan-d8-jquiss/404.php on line 10"
和：
PHP message: PHP Warning: Use of undefined constant XML - assumed 'XML' (this will throw an Error in a future version of PHP) in /data/wwwroot/www.crifan.com/wp-content/plugins/wp-syntaxhighlighter/wp-syntaxhighlighter.php on line 1048"
分别去看看代码
wp-content/themes/daqianduan-d8-jquiss/404.php
'order' => DESC,
看看如何处理
PHP message PHP Warning Use of undefined constant “DESC”
PHP message PHP Warning Use of undefined constant DESC
PHP Warning Use of undefined constant ‘DESC’
PHP constant ‘DESC’
PHP 常量 DESC
PHP 常量 “DESC”
PHP order 常量 “DESC”
如果你想降序排序，请使用 DESC 关键字。
语法 SELECT column_name(s) FROM table_name ORDER BY column_name(s) ASC|DESC
感觉应该是：
DESC -> 'DESC'
就可以了？
改写为：
'order' => "DESC",
结果：
真的就没这个错误了。
还剩：
PHP message: PHP Warning: Use of undefined constant XML - assumed 'XML' (this will throw an Error in a future version of PHP) in /data/wwwroot/www.crifan.com/wp-content/plugins/wp-syntaxhighlighter/wp-syntaxhighlighter.php on line 1048"
去看看代码
if ($wp_sh_brush_files[XML][3] == "true" || is_admin()) {
先去找找
wp_sh_brush_files XML
PHP wp_sh_brush_files XML
没找到有用的。
那估计是，直接改为 XML：
if ($wp_sh_brush_files["XML"][3] == "true" || is_admin()) {结果：
突然发现，还有更多地方，都是同样语法：
if (is_admin() && $wp_sh_brush_files[XML][3] == "false") {
if (is_admin() && $wp_sh_brush_files[PHP][3] == "false") {
if (is_admin() && $wp_sh_brush_files[XML][3] == "false") {
结果：
不过另外还有：
PHP message: evernote_sync_time()"
然后更新后，只有：
PHP message: evernote_sync_timer()" PHP message: evernote_sync_schedule 1 step" PHP message: evernote_sync_time()"
这次，就很少error的log了。
其实可以暂时忽略的。
去看看代码
// 设置定时器
function evernote_sync_timer()
{
error_log("evernote_sync_timer()");
if (!wp_next_scheduled('evernote_sync_cron')) {
error_log("evernote_sync_schedule 1 step");
wp_schedule_event(time(), 'evernote_sync_time', 'evernote_sync_cron');
}
}很是奇怪：为何此处代码，看起来没有逻辑错误，为何非要调用error_log去报错？
那就暂时忽略了。
【总结】
此处php代码报错：
/usr/local/php/var/log/php-fpm.log
PHP message: PHP Warning: Use of undefined constant PRC - assumed 'PRC' (this will throw an Error in a future version of PHP) in /data/wwwroot/www.crifan.com/wp-content/themes/daqianduan-d8-jquiss/comments.php on line 17"
之类错误，原因是：
应该传入字符串，但是此处传入的都不是字符串，而是无效的宏定义
所以代码从：
www.crifan.com/wp-content/themes/daqianduan-d8-jquiss/comments.php
date_default_timezone_set(PRC);
改为：
date_default_timezone_set("PRC");即可。
以及后续其他类似错误，也是通用处理方式：
把：
www.crifan.com/wp-content/themes/daqianduan-d8-jquiss/404.php
'order' => DESC,
改为：
'order' => "DESC",
把：
www.crifan.com/wp-content/plugins/wp-syntaxhighlighter/wp-syntaxhighlighter.php
if ($wp_sh_brush_files[XML][3] == "true" || is_admin()) {
。。。
if (is_admin() && $wp_sh_brush_files[XML][3] == "false") {
。。。
if (is_admin() && $wp_sh_brush_files[PHP][3] == "false") {
。。。
if (is_admin() && $wp_sh_brush_files[XML][3] == "false") {改为：
if ($wp_sh_brush_files["XML"][3] == "true" || is_admin()) {
。。。
if (is_admin() && $wp_sh_brush_files["XML"][3] == "false") {
。。。
if (is_admin() && $wp_sh_brush_files["PHP"][3] == "false") {
。。。
if (is_admin() && $wp_sh_brush_files["XML"][3] == "false") {即可。
