Batch string replace

I have a variable like this

"Folder With Spaces/filename.ext"

When I pass it to my program via PHP's system command, arguments are separated by spaces

system("batch.bat Folder With Spaces/filename.ext");

So I have it like this

system("batch.bat Folder_With_Spaces/filename.ex开发者_JAVA百科t");

Is there a way now that it is back in the batch program to replace the _'s with 's

try this in your batch file:

set str=hello_world_try_this
set str=%str:_= %
echo.%str%

---

Just enclose the parameter that has spaces with quotes.

system("batch.bat \"Folder With Spaces/filename.ext\"");

You may want to try escapeshellcmd(), like this:

$path = escapeshellcmd("Folder With Spaces/filename.ext");  
system("batch.bat \"$path\"");
