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 

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:

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.

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 

This works for me (reference):
