I think you'll have to read the file manually (file() would prob be the best
bet) and manually find/delete the line and then rewrite the file.

Can anyone help me figure out how to search for a string in a text file,

For example: I have a text file which contains the following.
//** text.txt **
Keep this line.
Also
Matt,
Try something like:
?
$fp=fopen(file_name.txt,r);
while (feof($fp))
{
$line=fget($fp,100); // grabs text to end of line or 100 characters
whichever comes first
if (!preg_match(/delete/,$line))
{
$new_line.=$line;
}
}
fclose($fp);
$fp=fopen(file_name.txt,w);
fwrite($fp,$new_line)
My bad:
while (!feof($fp))
instead of what I wrote earlier.

Matt,
Try something like
You could try...
$file = ( /path/file.ext );
$lines = sizeof ( $file );

Replace filename in both places, and linenumberyouwant.

file() will read the file into an array, one line per element, so...
Might not be the most secure way, but very fast...
$lines = `cat file.txt | wc -l`
That will give you the number of lines...but again not the best
method...
