[SOLVED] cache problem?

[gally]

Hi guys,

 

I've found a tool which transforms my MySql data in a .png graph image.

I use it inside a script and everything seems work nice. The problem is that only the first created graph is shown.

I' try to explain.

I've some Db tables, I select one to create the graph and it's shown, then I select another Db table, but it's shown always the first.

Looking inside the directory where the 2nd .png is created, I see data from the 2nd table, while from inside the script I see the 1st .png

I tried to remove the 2nd file from the dir, but nothing changes, so I think the 1st file is read fron the firefox cache.

Is there a way to clear the cache from inside a php script?

 

Following is part of the code actually I use

...
$graph->Stroke("pippo.png");
  //creates the image

echo "<img src = 'pippo.png' alt='grafico 1' />"; 
//shows the above image

if(is_file('pippo.png')) 
//remove the image from the dir for next processing
unlink('pippo.png');

 

Thank you in advance

2 options

 

HTML

<META HTTP-EQUIV="CACHE-CONTROL" CONTENT="NO-CACHE">

 

PHP

<?php
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
?>
