无法使用PHP打开日志文件

Question

I'm trying to open a log file located on my local machine from my web application hosted on websitepanel, but I keep getting this error message:

Warning: file(file:///C:/Program Files/FileMaker/FileMaker Server/Logs/Access.log) [function.file]: failed to open stream: No such file or directory in E:\\HostingSpaces\\ssd19aaron\\testproject.tureckidesign.com\\wwwroot\\application\\models\\logsmodel.php on line 91

This is the code:

$filename = 'C:/Program Files/FileMaker/FileMaker Server/Logs/Access.log';

$lines = file($filename, FILE_IGNORE_NEW_LINES);

Why won't the file open when I visit the site?

Answer 1

Because you try to get the file from C:/. Host your file on a logs folder inside your web application and edit the URL like this:

$filename = 'logs/access.log';

Answer 2

The computer provided by the Arvixe hosting service does not have the same file system as your local computer. You can't give it a file path for one computer and expect a program running on a different computer to find it. That is like trying to navigate Berlin using a map of Paris.

Generally speaking, to get a file from an HTTP client to an HTTP server you will use a form with a file input.

<form action="http://Arvixe-hosting-service/example.php" 
      method="post" 
      enctype="multipart/form-data">

<label>Log file <input type="file" name="log"> </label>
<input type="submit">

</form>

You can then read the file from

$_FILES['log']
