Bug description:fread does not fail when operating on a write only stream
Description:
------------
fread does not throw or generate any error when attempting to read from a
write only file stream.
Test script:
---------------
<?php
$tmp = tempnam(sys_get_temp_dir(), 'test_');
$stream = fopen($tmp, 'w');
$data = "";
while(!feof($stream)){
if(false === ($data .= fread($stream, 8192))){
break;
};
}
?>
Expected result:
----------------
Either feof to return false indicating end of file
Or fread erroring or returning false as a result of attempting to read a
write-only stream.
Actual result:
--------------
An infinite loop will occur.
feof will never end (doesn't reach the end of the file because it's in
write mode)
fread will never error despite attempting to read from a write only stream.
