Reading and Writing files to PHP

Posted 10 November 2011 - 05:11 PM

Hello, I'm reading through tutorials on opening files through php and my question is in one of the modes that is named x. It is suppose to be able to write into a new file or something of that nature. However when I put the x mode into the parameters I get an error message saying "Warning: fopen(welcome.txt) [function.fopen]: failed to open stream: File exists in C:\xampp\htdocs\test.php on line 79". I want to know how I can write into a file and if I'm reading and uploading a file do I have to put the text file in the same directory of the php file?



Here is my code if you want to see it
<html>
<head>
</head>
<body>
<br/>
<div style="border:solid black 1px; width:500px; display:block; margin-bottom:10px;">
<?php
$file=fopen("welcome.txt","x") or exit ("Unable to open file");
?>
</div>
</body>
</html>


Is This A Good Question/Topic? 0

According to my tutorial, opening a file with 'x', is requesting read/write file privileges.

Either the file doesn't exist, or the user permissions that your web server service is running under does not meet the required permissions to create a file handle with read & write privileges to welcome.txt.

I would start with checking both of those items.

You should also find the error description in your web server logs. I would assume this to be either IIS or Apache. Whichever it is, I'm sure you can find proper documentation will little effort as to the location of the logs.

according to your tutorial, opening an already existing file in "x" mode always fails …
