error when writing file

[psthree]

I am trying to learn PHP and how to write to a file
i have Php up and running on a mac

when I try to write to a file
I get this error

/Library/WebServer/Documents/Php/read_write/config.txt

Warning: fopen(config.txt) [function.fopen]: failed to open stream: Permission denied in /Library/WebServer/Documents/Php/read_write/configure.php on line 77
ERROR: cannot open configuration file for writing

this is the code that generates the error

//check file
    $configFile = 'config.txt';
    echo 'test<br>';
    echo file_exists($configFile). '<br/>';
    echo is_readable($configFile). '<br/>';
    echo is_writable($configFile). '<br/>';
    //echo stat($configFile). '<br/>';
    echo realpath($configFile). '<br/>';
    //open and lock configuration file for writing
    $fp = fopen($configFile, 'w+') or die ('ERROR: cannot open configuration file for writing');
    //flock($fp, LOCK_EX) or die ('ERROR: Cannot lock configuration file for writing');

 

I have checked all the file permissions and they are set to read/write
if I change the file I am writing to to .txt instead of .ini
I get different results with the file_exists is_readalbe, is_writable tests
Is there perhaps a setting that must be set in the php.ini file?
thank you!
for any insite

It has to be permissions. Is the file chmod'ed to 777 and can Apache write to that directory?

I personally would put the opening of the file into a function and individually check and return error messages as needed.

<?php

function openFile($file='config.ini')
{
    $file = realpath($file);

if(!file_exists($file))
{
    return '!!! File ('.$file.') does not exist!!';
}

if(!is_readable($file))
{
    return '!!! File ('.$file.') is not readable!!';
}

if(!is_writeable($file))
{
    return '!!! File ('.$file.') is not writeable!!';
}

$fp = @fopen($file, 'w');
if($fp === false)
{
    return '!!! File ('.$file.') failed to open for writing!!';
}

return $fp;
}

$myFilePointer = openFile();

if(!is_resource($myFilePointer))
{
    die($myFilePointer);
}

Try that, or take what's in the function and put it in your script and change the "return" to die()'s (except that last one, just remove the return $fp). Then give us the output.

Thank you for the exulant suggestions
I will try those
I did get the file to work
I copied another file and renamed it
It has the same permissions...
It works
It has the extention .txt
if i change it to .ini
it does not work!
if I change it back to .txt it does
Lead me to belive it was some thing in a ini file for php
I did not yet look in appachies
