Delete Whole Line

[Anon]

Whats the best way to go about deleteing a whole line?
say you have a file with:

(1) Some Line
(2) Some Line
(3) Some Line
(4) Some Line

and you want to delete just "(3) Some Line"
when you searched for "(3)"

Here is my code so far:

$list = "items.txt"; \ Text File
$oldword = "(3)"; \ Word To Find
$results = file($list); \ makes results a variable for the file
$newword = ""; \ Word to replace with
$fp = fopen("$list", 'r'); \ Opens the file and preforms the read command
if ($fp){
$data = fread($fp, filesize($list));
fclose($fp);
$newdata = str_replace($oldword, $newword, $data); \ Does the String Replacing
$fp = fopen($list, 'w');
if ($fp){
fwrite($fp, $newdata);
fclose($fp);
}
}

See what it does now is only replace (3) with "" this means the text file will now say:
(1) Some Line
(2) Some Line
Some Line
(4) Some Line

Is There a cure for this disease? If you have the vaccine please help me out.

There are several different ways to cure this....here is an easy one....
First, if instead of doing an fread, use fgets--this assumes that your lines are seperated by \n...then you can read in a line, and either add the line to an array, or write to a file, or whatever...

Hope this helps

==================================

I would go this Route but, the lines change every day and sometimes there are more lines in the file then the other, in actuallity they are html lines sort of like a guest book, (i know a database would be easier but i dont wanna learn more) So an array is out unless there is away to search throught the arrays with the text to find then delete it and rewrite the file

example (original):

(1) Line1
(2) Line2
(3) Line3
(4) Line4

After the delete:

(1) Line1
(2) Line2
(3) Line4

[tasistro]

$yourdata=@file("%filenamehere%");
// use unset to destroy array elements (lines)
// something like
unset($yourdata[2]); // destroys the 3rd line (we are counting from 0)

$fileoutput=implode('',$yourdata);

// then use file routines to open file for writing and write $fileoutput in one command

$fp = fopen ("%filenamehere", "w");

fputs($fp,$fileoutput);

...because I CAN!

$file=file($filename);
$kill=preg_quote("(3)");
$newfile=preg_grep("/^{(?!$kill).*/",$file);}
...open $filename and write the lines in $newfile to it.
