This always works for me:
ini_set('display_errors', '1');
ini_set('display_startup_errors', '1');
error_reporting(E_ALL);
However, this doesn’t make PHP to show parse errors – the only way to show those errors is to modify your php.ini with this line:
display_errors = on
(if you don’t have access to php.ini
, then putting this line in .htaccess
might work too):
php_flag display_errors 1
