Question

Collating some data week by week I serialized an array of the appropriate data and output that to a temporary file using file_put_contents.

Inclusive of some output statements to try and establish what is happening the code looks like this:

    echo "<br/> collate session data <br/>";
    print_r($this->session_Data);
    $serialized_Array = serialize($this->session_Data);
    $file_Name =  'session_Data_' . $this->week_Number;
    echo "file_Name: " . $file_Name; 
    file_put_contents($file_Name, $serialized_Array);

The file name definitely gets updated appropriately and there is definitely data to output.

But this will only ever output the first weeks data to the tmp file.

I get no permission errors I get status 200 OK but no files are created.

Am I missing something here??

You are writing the file in the same directory as the script. In a default configuration the webserver process has only read and execute rights in that directory.

• create a separate directory for the files, and give the webserver process write permission to that folder.
• give the webserver process write permission to the folder the script is in. Be aware that this can be a security issue.
