Clearing a line in a text file

[ybh]

Hey guys-

Sorry if this seems simple, but does anyone have a function I can call where as I specify a filename, and the function will go line by line and see if a specific phrase is found and if it is found, it will delete the entire line?

If anyone could help me out with this, I would certainly appreciate it.

Thanks!

<?
$file = "http://www.example.com/phile.txt";
$fp = fopen( $file, "r" ) or die("couldn't open $file");
while ( ! feof( $fp )) { $text[] = fgets( $fp, 1024 ); }
reset($text);
fclose($fp);

foreach($text as $key => $value)
{
	if (!strstr($value,'some text'))
	{ 
		$result.=$value;
	}

}
?>

If it finds text: "some text" in the file, it wont add the line to variable $result.
