Send http-404 response BUT dont send custom error page setted in IIS server | PHP -

lets understand scenario:

:- using php web application on iis 8.5

:- custom error page set 404 following web-config snippt:

<httperrors errormode="custom" existingresponse="replace">     <remove statuscode="404" substatuscode="-1" />     <error statuscode="404" path="/path/404.php" responsemode="executeurl" /> </httperrors> 

:- working non-existing page and iis also return 404.php if set header 404 (via header('http/1.0 404 not found', true, 404); die;) in php page.

question:

now, wan send 404 http response code in php-file on specific condition, lets if database returns 0 rows. can setting header above return custom error page also. is there way send 404 code , tell iis send response is, without sending custom error page along it?

issues:

:- if remove custom error page , put content between header() , die() meet requirement iis fail serve custom error on pages doesn't exist.

:- using url rewrite cannot use multiple custom error pages based on location tag , don't want redirect suggested different urls.

as have 1 tricky solution/idea, want share also. if have better solution, welcome , them.

trick/solution/idea:

step 1:- existing php-page set session variable before header('http/1.0 404 not found', true, 404); , put specific message in variable(i suggest use different integer code session variable's value different php-pages) set header , call die(); or exit;.

step 2:- after iis or other server execute custom error page. so, in custom error page check session variable , echo content follows....

........2a - if session variable not set display "normal error content main menu" etc.

........2b - if session variable set check value , according value display different content want show user like: "data not found message , search panel"

note: in custom error page's coding again need set 404 header, , can send different error code according session variable's value in above trick.
