Reading From File

[chugger93]

Can anyone help out with reading from a file and saving the current contents? What I have is, a script that writes data
to a file, but everytime u click a button, it overwrites the data.

How can I with my current code, save the current contents
above the old contents, according to the date in my file?
Does that make sense?

So for example my file would look like this:

July 21st 2004

What a great day it is

Woohooo!


July 20th 2004

Hello Word

How are you

Here is my script code

<?

if(isset($_POST['check'])) { 
//itterate through check boxes to check which are checked
  foreach($_POST['check'] as $key => $value) { 

$today = date("F-d-Y");
$filename = $today.".ticker_archive.html";
$path = "C:/Inetpub/wwwroot/bna-intranet/ticker_archive/";

$somecontent =  "<table><tr><td><font face=\"$fontstyle\" color=\"$fontcolor\" size=\"$fontsize\">".$value."</font></tr></tr></table><br />";


// Let's make sure the file exists and is writable first.

   // In our example we're opening $filename in append mode.
   // The file pointer is at the bottom of the file hence 
   // that's where $somecontent will go when we fwrite() it.
   if (!$handle = fopen($filename, 'a')) {
         echo "Cannot open file ($filename)";
         exit;
   }

   if (fwrite($handle, $somecontent) === FALSE) {
       echo "Cannot write to file ($filename)";
       exit;
   }

  echo "<p align='left'><b>Successfully</b>, wrote (<font face=\"$fontstyle\" color=\"$fontcolor\">". strip_tags($somecontent) ."</font>) to file<br />";
   fclose($handle); 

}

echo "<br /><br /><br /><br />"; 

// Copies the file over to another directory

  if (!copy($filename, $path.$filename)) {
   echo "Failed to copy $filename...<br />\n"; 
} else {
echo "Your file <u>$filename</u> has been copied too $path<br /><br />\n"; }

// After the file has been copied, it gets deleted

if (file_exists($filename))  

    {  

         unlink($filename); 

}else{  
    echo ("$filename could not be found!"); 
}  

  // foreach loop end bracket
} else { 
  echo "<font size='2'>I'm Sorry, No boxes are checked!</font><br/>\n"; 
} 

?>

I do run searches, but nothing ever really helps perfectly.

I tried that code posted. cant get it to work, still overwrites

$filename = "ticker_archive.html";
$path = "C:/Inetpub/wwwroot/bna-intranet/ticker_archive/";

$somecontent =  "<table><tr><td><font face=\"$fontstyle\" color=\"$fontcolor\" size=\"$fontsize\">".$value."</font></tr></tr></table><br />";


$new_post = "$somecontent"; 
$new_post .= file_get_contents( "ticker_archive.html" ); 

$fl = fopen( "ticker_archive.html" , "w" ); 
fwrite ( $fl , $new_post ); 
fclose( $fl );




  echo "<p align='left'><b>Successfully</b>, wrote (<font face=\"$fontstyle\" color=\"$fontcolor\">". strip_tags($somecontent) ."</font>) to file<br />";
   fclose($handle); 

}

Another useful source of information is the manual. See the page for [man]fopen[/man]; Table 1.

I seriously cant get this to work. I've done a search and have tried like 9 different types of code for opening and reading files.

The content will not go on the top, neweset I mean...

take this code for instance...

$filename = "ticker_archive.html";
$path = "C:/Inetpub/wwwroot/bna-intranet/ticker_archive/";

$somecontent =  "<table><tr><td><font face=\"$fontstyle\" color=\"$fontcolor\" size=\"$fontsize\">".$value."</font></tr></tr></table><br />";



   // In our example we're opening $filename in append mode.
   // The file pointer is at the bottom of the file hence 
   // that's where $somecontent will go when we fwrite() it.
   if (!$handle = fopen($path.$filename, 'a')) {
         echo "Cannot open file ($filename)";
         exit;
   }
echo implode("<br>",array_reverse(file("$path.$filename")));

   if (fwrite($handle, $somecontent) === FALSE) {
       echo "Cannot write to file ($filename)";
       exit;
   }

fclose($handle);

Ok I think I got it with this code....but sometimes my data gets corrupted... the html displays as regular text. What can I do about this?

$file = '$path.$filename';
$fp = fopen($path.$filename,'r+');
$str = fread($fp,filesize($file));
rewind($fp);
fwrite($fp,$somecontent.$str);
fclose($fp);
