Replacing a line of txt

[Schwalbach]

Hey guys,

I wrote a file, and being a newbie I think I messed up somewhere...I will explain it:

<?php
$filename = 'shoutbox.txt';
$file = file($filename);
$delete = $delete;
$new = str_replace($file[$delete],"",$file);
echo($new);
$handle = fopen($filename, 'w');
fwrite($handle, $new);
?>

Ok guys, the $delete variable is a var from flash, that equals 1,2,3, etc of the variable(It is the line of the file) whenever I run this script, the new written file changes to "Array" and that's all....so what am I doing wrong?

Thanks guys 🙂

Ok guys, redid my code and came out with this:

<?php

$linedelete = '$delete';

$filename = 'shoutbox.txt';

$file = file($filename);

unset($file[$linedelete]);

$fp = fopen($filename,'w');

fwrite($fp,$file);

fclose($fp);

?>

Still coming out with array in the text file...the delete is all right, and seems to be sending the right data, but just coming out with array...sorry for bothering you guys with such a stupid question.

It's because you have an array of information in there. You'll want to loop through the results and write them back. Or write it to a string instead of an array. Take a look at these threads

Hey,

I got something here, but not quite....here is my new code. It only shows the first line now, no matter what I enter to delete in the flash file. It just basically deletes everything but the first line now..any Ideas?

<?php

$linedelete = '$delete';

$filename = 'shoutbox.txt';

$file = file($filename);
unset($file[$linedelete]);
$fp = fopen($filename,'w');
for($i=0; $i<=count($file);$i++) {
$file=$file[$i];
fwrite($fp,$file);
fclose($fp);

}
?>

Okay, I'm really sick so I can't be in front of the computer too much today. Here's your answer:

$linedelete = $delete;
$filename   = "shoutbox.txt";
$file       = file($filename);
unset($file[$linedelete]);

$fp = fopen($filename,"w");

$text = "";
foreach($file as $f) {
   $text .= $f;
}

fwrite($fp,$text);
fclose($fp);

After deleting, it sets $text as a big string o what you want to write back, then writes it all at once. Remember though: You're array starts at zero. So if $linedelete = 4, it will actually delete line 5.
