how to redirect STDOUT to a file in PHP?

Question

The code below almost works, but it\'s not what I really meant:

ob_start();
echo \'xxx\';
$contents = ob_get_contents();
ob_end_clean();
file_put_contents($f

You can install Eio extension

pecl install eio

and duplicate a file descriptor

$temp=fopen('/tmp/my_stdout','a');
$my_data='my something';
$foo=eio_dup2($temp,STDOUT,EIO_PRI_MAX,function($data,$esult,$request){
    var_dump($data,$esult,$request);
    var_dump(eio_get_last_error($request));
},$my_data);
eio_event_loop();
echo "something to stdout\n";
fclose($temp);

this creates new file descriptor and rewrites target stream of STDOUT

this can be done with STDERR as well

and constants STD[OUT|ERR] are still usable
