How can I get MAMP to tell me what went wrong with php code?
提问by Ulmer
Whenever I have an error in my php code, MAMP just returns a 500 error. Is there anyway I can get MAMP to tell me what went wrong like parsing errors and stuff?
每当我的 php 代码出错时，MAMP 只会返回 500 错误。无论如何，我可以让 MAMP 告诉我解析错误之类的错误吗？

Just as you reported, you must have display_errorsset to on. This can be done either by changing the conf file or by using .htaccess like so:
正如您报告的那样，您必须display_errors设置为on。这可以通过更改 conf 文件或使用 .htaccess 来完成，如下所示：
<IfModule mod_php5.c>
php_flag display_errors on
</IfModule>
Additionally, you can do this with ini_set()like so:
此外，您可以ini_set()像这样执行此操作：
ini_set('display_errors', 1);
One last thing, you can also check /Applications/MAMP/logswhich has three different error log files.
最后一件事，您还可以检查/Applications/MAMP/logs哪个具有三个不同的错误日志文件。
Try opening terminal and run this command:
尝试打开终端并运行以下命令：
tail -f /Applications/MAMP/logs/php_error.log
When you want to stop "following" (the -fswitch) the log file, just type control+C.
当您想停止“跟踪”（-f开关）日志文件时，只需键入control+C。

You can also access MAMPerrors using the Mac "Console" appto read the php_error.logfile.
您还可以使用 Mac “控制台”应用程序访问MAMP错误以读取文件。php_error.log
I find this easiest to access by using spotlight and typing in "error.log".
我发现通过使用聚光灯并输入“error.log”最容易访问。
( it won't find it if you type "php_error.log", you must type "error.log" )
（如果你输入“php_error.log”它不会找到它，你必须输入“error.log”）
It looks like this :
