Check for files

[kney]

Hi,

 

Here's my problem:

 

The first 5 or 10 tries it should say "file not found".

After the 10th try it should automatically say "file found".

BUT it should also time out after like 50 tries and it hasn't found the file.

But i don't know how to do this..

 

I currently have this code:

 

<?php

function respond_xml($status, $message)
{
    $out = new XMLWriter();
    $out->openURI("php://output");
    $out->setIndent(true);

    $out->startDocument("1.0", "ISO-8859-1");

    $out->startElement("statuscheck");
    $out->writeElement("status", $status);
    $out->writeElement("message", $message);
    $out->endElement();

    $out->endDocument();
    
    $out->flush();
}

function main()
{
    header("Content-type: text/xml");

    if (!isset($_GET["file"]))
        respond_xml("ERROR", "File parameter missing");
    else if (file_exists($_GET["file"]))
            respond_xml("OK", "File exists");
    else
           respond_xml("NOT OK", "File does not exist");
}

main();

?>

 

This code works and gives a correct XML response when you type in for example "http://localhost:8080/php/script.php?file=test" it's says:

<statuscheck>
<status>NOT OK</status>
<message>File does not exist</message>
</statuscheck>

 

Now, I need it to be able to check it every 5 seconds so i've use this code

header("Refresh: 5; URL=http://localhost:8080/php/script.php?file=test");

You can set a count in a session variable when the page is first loaded and then increment it each time it reloads. Then you can check the count and decide to check for the file or show the timeout message, right?
