Bug description: file_put_contents writes empty file with zlib and LOCK_EX
Description:
------------
When passing LOCK_EX to file_put_contents() using a "compress.zlib"
stream, the function creates a valid gzip file (non-empty) containing zero
un-compressed bytes (gunzip outputs nothing) and returns false.
This was reported in #42468, but wasn't actually fixed. The function
needs to fail BEFORE it opens (and destroys) the output file.
Reproduce code:
---------------
<?
$name = "/tmp/hello.txt.gz";
$file = "compress.zlib://" . $name;
var_dump(file_put_contents($file, "hello", LOCK_EX));
var_dump(filesize($name));
var_dump(file_get_contents($file));
?>
Expected result:
----------------
int(5)
int(31)
string(5) "hello"
Actual result:
--------------
bool(false)
int(26)
string(0) ""
