Description:
------------
fgets() returns a charecter when it fails to read from file because of
following reasons:
1. file pointer already points to end of the file(file opened in
mode)
2. File is opened in the write only mode
Only applicable to php6.
PHP Version:
PHP 6.0.0-dev (cli) (built: Jul 18 2007 20:53:03) (GCOV)
Copyright (c) 1997-2007 The PHP Group
Zend Engine v3.0.0-dev, Copyright (c) 1998-2007 Zend Technologies
OS: RHEL 5
Config :
./configure --enable-gcov
Reproduce code:
---------------
<?php
$file_handle = fopen("test.txt", "w");
$data = "testing fgetc";
fwrite($file_handle, $data);
// rewind the file pointer to begining of the file
var_dump( rewind($file_handle) );
var_dump( ftell($file_handle) );
var_dump( feof($file_handle) );
// read from file
var_dump( fgetc($file_handle) );
var_dump( ftell($file_handle) );
var_dump( feof($file_handle) );
fseek($file_handle, 0, SEEK_END);
var_dump( fgetc($file_handle) );
fclose($file_handle);
unlink("test.txt");
?>
Expected result:
----------------
bool(true)
int(0)
bool(false)
bool(false)
int(0)
bool(false)
bool(false)
Actual result:
--------------
bool(true)
int(0)
bool(false)
string(1) ""
int(0)
bool(true)
string(1) ""
output when run using run-test.php:
-----------------------------------
bool(true)
int(0)
bool(false)
string(1) "ÿ"
int(0)
bool(true)
string(1) "ÿ"
