How to remove a line from text file using php without leaving an empty line
16,020
$DELETE = "the_line_you_want_to_delete";
$data = file("./foo.txt");
$out = array();
foreach($data as $line) {
if(trim($line) != $DELETE) {
$out[] = $line;
}
}
$fp = fopen("./foo.txt", "w+");
flock($fp, LOCK_EX);
foreach($out as $line) {
fwrite($fp, $line);
}
flock($fp, LOCK_UN);
fclose($fp);
this will just look over every line and if it not what you want to delete, it gets pushed to an array that will get written back to the file.

currently I am able to remove a specific line from text file using php. However, after removing that line, there will be an empty line left behind. Is there anyway for me to remove that empty line so that the lines behind can move up? Thank you for your help.
