Dear All,

Thanks in advance.

I am compiling an .as file with mxmlc on the fly using PHP.

CODE:

exec(“mxmlc example.as”,$retval,$success);  
print\_r($retval);

The output of above is just:  
Array ( [0] =\> Loading configuration file /site/fsdk/frameworks/flex-config.xml )

Whereas actually, when I execute “mxmlc example.as” (From command line linux) I get many errors as:

public class My\_273860 extends Sprite asdfasfasf  
^

I want to catch all the errors:

Please help,  
Thanks.
