help with rewind

[Anon]

im trying to use rewind to write to the beginning of a text file and push everything else in the file down so it doesnt get overwritten. ive tried many different things to try to get it to work but its just not working. any help would be much appreciated.

you'll have to fisrt read the file contents after you open it, rewind, and write your new data, then append the old content to it

so what you are saying is set it up like this??

$old = fopen("text.txt","r");
rewind($old);
$new = fopen("text.txt","w");
fwrite($new,"content<br><br>");
$write = fopen("news.txt","a");
fwrite($write,"$old");

when i do that tho all it does is write whatever the new data is. it doesnt even bother to rewrite the stuff i opened

[Anon]

that "news.txt" in the open for $write should be "text.txt"

anyone? i hate to beg but i would just like to get this script working

It didn't work because you didn't do what I said. I told you you need to first read the old data and then append it to the new and THEN write it to the file.

<?
$newData = "some text\n";

$fp = fopen($myFile,'rw');
$oldData = @fread($fp,filesize($myFile));
rewind($fp);
fwrite($fp, $newData . $oldData);
fclose($fp);
?>

Or you could try this:

<?
$newStuff="new content\n";
$readFile=fopen("somefile.txt","r");
while(!feof($readFile)) {
$oldStuff[]=fgets($readFile,255)."\n";
}
fclose($readFile);

$writeFile=fopen("somefile.txt","w");
fputs($writeFile,$newStuff);
for(var $x=0;$x<count($oldStuff);$x++) {
fputs($writeFile,$oldStuff[$x]);
}
fclose($writeFile);
?>

Hope that helps!

Happy coding! 🙂

But why open and close the file twice and use twice the amount of function calls?
Better to work with it all at once and have less code.

LOL - I don't know. Just giving penography the "novice" version 🙂.

Happy coding! 🙂
