尝试phpinfo()并检查“error_log”

无论你想要它在哪里，如果你在函数调用中设置它:

error_log($errorMessageforLog . "\n", 4, 'somePath/SomeFileName.som');

尝试phpinfo()并检查“error_log”

因为某种原因，我把它存储在:

/ var / log / php-errors日志。

我使用的是Ubuntu Server 16.04 (Xenial Xerus)和PHP 7.1.28。

你可以在下面看到一个帐户的php错误:

/home/username/logs/domain_tld.php.error.log

可以在全局和本地设置php错误日志。

WordPress

当WP_DEBUG_LOG设置为true时，WordPress会将error_log()消息直接指向/wp-content/debug.log。
