php exec function?

Question

PHP

OS: windows 10;
Apache, PHP7;
I need to run an OS function, namely run ogr2ogr to convert from geojson to postgis (PostgreSQL). Maybe I need to give apache permissions.

var_dump(exec('"C:\Program Files\GDAL\ogr2ogr.exe" -f "PostgreSQL" -a_srs "EPSG:2249" 
    PG:"dbname=postgis20 user=postgres password=1" "C:\Apache24\htdocs\temp_files\file.json" -nln ABC1 -append', $output, $return));

log

PS from cmd this conversion works!

var_dump will not output anything, everything is in output and return_var but add 2>&3 or 2>&1 at the end of the command and check what's in output
