Dear All,  
Thanks in advance.

I have the following problem  
When i execute following line from my command prompt  
c:\flexsdk3\bin\mxmlc.exe c:\users\222131\Simple01\Simple01\_222131.as -output c:\out.swf

It works fine.,

But when I do the same with  
exec(“c:\flexsdk3\bin\mxmlc.exe c:\users\222131\Simple01\Simple01\_222131.as -output c:\out.swf”) in php it doesnt work.

Can any one help with this.?

Thanks
