Why MAMP doesn't display errors?
PhpError HandlingMampPhp Problem Overview
OK this is getting very frustrating. MAMP used to display errors but then stopped. I decided to do a fresh install of it as I couldn't figure it out. I check my PHP version, running 5.4.4 and go to that folder and change the php.ini to this:
error_reporting = E_ALL
display_errors = On
Still no errors showing. I go through all the folders and change all php.ini files, just in case. Nothing. I fix the forced error and dump out phpinfo(), check the error section and display_errors is Off. What the hell.
I place error_reporting(E_ALL); ini_set('display_errors', 'on'); at the start of the PHP file and phpinfo() again. Local value is now On, master is still Off. Force a PHP error, and still get Server Error not PHP error.
Anybody have any insight? I have a bug somewhere in some code and cannot find it, would love for PHP to just tell me.

MAMP sets up a few different php.ini files for the server, the client etc. Check in your phpinfo() which php.ini actually is read. Looks like you're editing the wrong one.
Solution 2 - Php
There are two php.ini files on MAMP. You should change both php.ini files.
Applications/MAMP/bin/php/'php version you are using(php5.5.10)'/conf/php.iniApplications/MAMP/conf/php/'php version you are using(php5.5.10)'/conf/php.ini
Then change:
display_errors = Off
to:
display_errors = On
Solution 3 - Php
If you're using MAMP PRO, you've to enable Error handling (PHP) in the UI interface which should contain at least two the main options: 'Display startup errors' and set output 'To: Display'.
Display startup errors option is equivalent to display_startup_errors (in PHP) and To: Display to display_errors.
See below:
Solution 4 - Php
Change the setting in your php.ini file. The file is located in MAMP > conf > php5 > php.ini
Look for display_errors = Off and change to display_errors = On
After that you need to restart your Apache and MySQL servers for the change to take effect.

MAMP PRO users can visit the PHP tab in UI and make sure Log Errors: to screen is checked: http://www.screencast.com/t/EhMpl3aU">screencast</a>

Here's a 2018 update to this problem. First, I'm having the same trouble and found this thread. I used phpinfo() and found yet another location of a php.ini file. Here are the paths (I work on a Mac):
/Applications/MAMP/bin/php/[php version]/conf/php.ini
/Applications/MAMP/conf/php/[php version]/php.ini
and ...
/Library/Application Support/appsolute/MAMP PRO/conf/php.ini
The phpinfo() page lists two sources for the php.ini:
- Configuration File (php.ini) Path
/Applications/MAMP/bin/php/[php version]/conf - Loaded Configuration File /Library/Application Support/appsolute/MAMP PRO/conf/php.ini
I ended up changing all three, adding error_reporting(E_ALL) to some pages, restarting the server (even rebooted the machine) and still cant get it to display any error messages.
I'm not sure where to go from here. Any ideas?
**** ---------------------------------------------- **** 2020 Edit **** ---------------------------------------------- **** The latest MAMP upgrade (v6) has changed the main web host directory. It's not in the Applications/MAMP/ directory. That's a good thing. But it required me to change where all my projects live. I had to reconfigure my IDE, Postman, Git, and some others. So, I figured this would be a perfect time to move to Docker containers.
Docker brings a whole new level of challenges but once I got familiar with it and deployed a few containers, it's been great. It feels faster when rendering in the browser and I am more confident that my projects will run as expected on the production server. Eventually our production servers will use containers, so it just makes sense for me.

If you are using MAMP version 3.2.2 then you only need to change one php.ini file:
Mac: Applications/MAMP/conf/'(php7.0.9)'/php.ini
Windows: C:\MAMP\conf\PHP Version you use'(php7.0.9)'\php.ini
I know this is an old post but MAMP keeps changing their configuration of the files so I hope this helps.
Solution 8 - Php
For newer versions of MAMP, the config file is stored in Appliations/MAMP/bin/php/[php version]/conf.
Andrew Nagy pointed me in the right direction with his answer, but it wasn't quite correct for my installation of MAMP. Why they're different, I can't tell, but here we are.
If anyone is stuck, the easiest thing to do is to just <?php echo phpinfo(); ?> in the index file of the application and look for the loaded php.ini directory.
Solution 9 - Php
Also there is a template saved in MAMP of the php.ini.
Go to File > Edit Template > PHP > Your Version.
Solution 10 - Php
On MAMP 3.2.0 and PHP 7 you'll need to target php.ini-production and change the value to Production Value = On
