Enabling error display in PHP via htaccess only

I am testing a website online.

Right now, the errors are not being displayed (but I know they exist).

I have access to only the .htaccess file.

How do I make all errors to display using my .htaccess file?

I added these lines to my .htaccess file:

php_flag display_startup_errors on
php_flag display_errors on
php_flag html_errors on

And the pages now display:

Internal server error

.htaccess:

php_flag display_startup_errors on
php_flag display_errors on
php_flag html_errors on
php_flag log_errors on
php_value error_log /home/path/public_html/domain/PHP_errors.log

This works for me (reference):

# PHP error handling for production servers
# Disable display of startup errors
php_flag display_startup_errors off

# Disable display of all other errors
php_flag display_errors off

# Disable HTML markup of errors
php_flag html_errors off

# Enable logging of errors
php_flag log_errors on

# Disable ignoring of repeat errors
php_flag ignore_repeated_errors off

# Disable ignoring of unique source errors
php_flag ignore_repeated_source off

# Enable logging of PHP memory leaks
php_flag report_memleaks on

# Preserve most recent error via php_errormsg
php_flag track_errors on

# Disable formatting of error reference links
php_value docref_root 0

# Disable formatting of error reference links
php_value docref_ext 0

# Specify path to PHP error log
php_value error_log /home/path/public_html/domain/PHP_errors.log

# Specify recording of all PHP errors
# [see footnote 3] # php_value error_reporting 999999999
php_value error_reporting -1

# Disable max error string length
php_value log_errors_max_len 0

# Protect error log by preventing public access
<Files PHP_errors.log>
 Order allow,deny
 Deny from all
 Satisfy All
</Files>

I feel like adding more details to the existing answer:

# PHP error handling for development servers
php_flag display_startup_errors on
php_flag display_errors on
php_flag html_errors on
php_flag log_errors on
php_flag ignore_repeated_errors off
php_flag ignore_repeated_source off
php_flag report_memleaks on
php_flag track_errors on
php_value docref_root 0
php_value docref_ext 0
php_value error_log /full/path/to/file/php_errors.log
php_value error_reporting -1
php_value log_errors_max_len 0

Give 777 or 755 permission to the log file and then add the code

<Files php_errors.log>
     Order allow,deny
     Deny from all
     Satisfy All
</Files>

at the end of .htaccess. This will protect your log file.

These options are suited for a development server. For a production server you should not display any error to the end user. So change the display flags to off.

If you want to see only fatal runtime errors:

php_value display_errors on
php_value error_reporting 4

php_flag display_errors on

To turn the actual display of errors on.

To set the types of errors you are displaying, you will need to use:

php_value error_reporting <integer>

Combined with the integer values from this page: http://php.net/manual/en/errorfunc.constants.php

Note if you use -1 for your integer, it will show all errors, and be future proof when they add in new types of errors.
