fopen(), fwrite() function is not working in php

Question

Below is my code,

test.php

<?php
$prefixnew = "testnew";
$file1 = fopen("testnew.txt","w");
$content_wr_g = "Test sitest"
fwrite($file1,$content_wr_g);
fclose($file1);
?>

test.bat

@ECHO off


C:\wamp\bin\php\php5.3.13\php.exe -f  "C:\...\test.php"


popd

UPDATE

When i run (test.php) directly from browser it is working properly. if i run from scheduled tasks, it is not working.

I know very well about task scheduler steps to create a task. When i run set of update queries or delete queries means, it working nicely.

When i have code like fopen(), fwrite() etc it is not working

Answer 1

Instead of using relative path, use absolute path to the file:

$file1 = fopen(__DIR__.'/testnew.txt', 'w');

I assume you are using >= PHP 5.3 , if not try:

$file1 = fopen(dirname(__DIR__).'/testnew.txt', 'w');
