Bug description: feof() hangs
Description:
------------
The code below works fine with PHP 5.2.6 (and earlier), but not with the
unreleased PHP 5.2.7 and PHP 5.3.0:
892 $handle = @fopen($url, 'r');
893
894 if (!$handle) {
895 throw new RuntimeException(
896 'Could not connect to the Selenium RC server.'
897 );
898 }
899
900 stream_set_blocking($handle, 1);
901 stream_set_timeout($handle, 0, $this->timeout);
902
903 $info = stream_get_meta_data($handle);
904 $response = '';
905
906 while ((!feof($handle)) && (!$info['timed_out'])) {
907 $response .= fgets($handle, 4096);
908 $info = stream_get_meta_data($handle);
909 }
910
911 fclose($handle);
The code above hangs with PHP 5.2.7 and PHP 5.3.0 in line 906 as shown
using Xdebug's tracing:
fopen() Driver.php:892
stream_set_blocking() Driver.php:900
stream_set_timeout() Driver.php:901
stream_get_meta_data() Driver.php:903
feof() Driver.php:906
fgets() Driver.php:907
stream_get_meta_data() Driver.php:908
feof() Driver.php:906
The second feof() call above hangs.
More information can be found here:

Changing the loop to
while (!$info['eof'] && !$info['timed_out']) {
$response .= fgets($handle, 4096);
$info = stream_get_meta_data($handle);
}
fixes the problem. This means a difference between feof() and
$info['eof'].
