Function: convert the image format by using an external program. (no write method is supported. you can use shell. However, if PHP returns 1, the statement is incorrect)

exec("c:/Program Files/IrfanView/i_view32.exe c:/Program Files/IrfanView/03280009.sff /convert=c:/Program Files/IrfanView/4.tif", $result, $status); 
echo $status;

exec("c://Program Files//IrfanView//i_view32.exe c://Program Files//IrfanView//03280009.sff /convert=c://Program Files//IrfanView//4.tif", $result, $status); 
echo $status;

exec("c:\Program Files\IrfanView\i_view32.exe c:\Program Files\IrfanView\03280009.sff /convert=c:\Program Files\IrfanView\4.tif", $result, $status); 
echo $status;

exec("c:\\Program Files\\IrfanView\\i_view32.exe c:\\Program Files\\IrfanView\\03280009.sff /convert=c:\\Program Files\\IrfanView\\4.tif", $result, $status); 
echo $status;

PHP? Help? System commands

------ Solution --------------------
Grant the general user the execution permission to C: \ Program Files \ IrfanView> I _view32.exe
------ Solution --------------------
"C:/Program Files/IrfanView/I _view32.exe

In this case, the red part is used as the parameter (equivalent to an incorrect doscommand), and the path contains spaces to use quotation marks.
