<?php
$a="a / b";
$a=preg_replace('/\//','\\',$a);
echo file_put_contents("rw.txt", $a);
$a=preg_replace('/\//','\\\\',$a);
echo file_put_contents("rw.txt", $a);
?>
outputs 55 and rw.txt contains a \ b which it should not. no it's not open in an editor. create
always is not enabled in the interpreter. 2nd write fails to write to file, same as before.
5==strlen($a).

Thanks for checking this issue, fernando. I don't know what's
wrong in the OP's case, but I suggest to check the return values
of all three functions.

Can't reproduce this issue on a Windows 8 with PHP 7.1 Beta 3 from windows.php.net QA
I tried with a local path and with a SMB remote path:
<?php
error_reporting(E_ALL);
file_put_contents('test.txt', "HOLA");
var_dump(file_get_contents('test.txt') == "HOLA");
file_put_contents('test.txt', "ADIOS");
var_dump(file_get_contents('test.txt') == "ADIOS");
file_put_contents('\\\\server\folder\test.txt', "HOLA");
var_dump(file_get_contents('\\\\server\folder\test.txt') == "HOLA");
file_put_contents('\\\\server\folder\test.txt', "ADIOS");
var_dump(file_get_contents('\\\\server\folder\test.txt') == "ADIOS");
D:\fms\php710beta3>php file.php
bool(true)
bool(true)

yes, error reporting was set for E_ALL.
I cannot compile php. requires languages and utilities I do not have.
I don't have linux.
this is on windows vista.

Is it possible that this editor locks the file? Please enable
error_reporting=E_ALL, and see if there are any warnings shown.

Did you compile the php.exe binary with GCC? The officially
distributed php.exes are compiled with Visual C++.

Description:
------------
file_put_contents() does not overwrite if file exists. if file exists, file is not touched. if file
is open in programmer's editor, rw.txt file does not refresh. this could be related with c++
old gcc bug in fstream's std::ios_base::creat notworking for while a number of years.
Test script:
---------------
<?php
$a=file_get_contents("\\w\\Jesusnjim\\menu7a.xml");
$a=preg_replace('/\//','\\',$a);
file_put_contents("\\w\\Jesusnjim\\rw.txt", $a);
?>
2nd time:
<?php
$a=file_get_contents("\\w\\Jesusnjim\\menu7a.xml");
$a=preg_replace('/\//','\\\\',$a);
file_put_contents("\\w\\Jesusnjim\\rw.txt", $a);
?>
Expected result:
----------------
expected / to be changed to \\ and for rw.txt to be changed in programmer's editor jedit and to
be notified that file was changed.
Actual result:
--------------
if file is open in programmer's editor, rw.txt file does not refresh.
