fopen() help

[Dybbuk]

ok im new to PHP and i really dont know if this can be done but i figured id ask to see. im using fopen() to write to a text file. The problem I am having is I can make it write data from Oldest down to Newest with the fopen($filename, "a") but I want to make it write data from Newest to Oldest with it pushing the old text on down the file. ive tried fopen($filename, "r+") but that didnt work it just wrote over my data. Can anyone help? Thanks in advanced.

Well, depending on what you're using fopen(), there are a couple of possible solutions. If you simply want to eventually be able read the data sorted from newest to oldest, than you can use $array = rsort(file("filename.txt")).

If you actually need the data written from newest to oldest, then it's a little more complex. Assuming all the data in the file is already in the order it needs to be, then this might work:

<?

// Puts the current contents of the file into a string
$file_contents = file_get_contents("filename.txt");

// Opens the file for writing
$file = fopen("filename.txt","w");

$new_data = "New string to be added\n";

// Write new data then write the older file contents
fwrite($file,$new_data.$file_contents);

// Close the file
fclose($file);
?>
