Why does the value of short_open_tag in the nginx config need to be specified through php_value, and not through php_flag?

Question

Nginx

Help clarify the situation with the php_value and php_flag parameters.

php_value name value
Sets the value of the designated directive. Can only be used with directives like PHP_INI_ALL and PHP_INI_PERDIR To clear previous values ​​set, use none.

php_flag name on|off
Used to set boolean values ​​to directives. Can only be used with directives like PHP_INI_ALL and PHP_INI_PERDIR.

I want to set the value of the short_open_tag on/off parameter from the nginx config. I write fastcgi_param PHP_FLAG "short_open_tag=on"; nothing changes, and if I write fastcgi_param PHP_VALUE "short_open_tag=on";, then everything starts working. Help me figure out why this is happening?

Answer 1

Vsb life through php_value in nginx was done, but I didn’t even know about the flag.
