[SOLVED] Replace Line

[lalabored]

I have a file named lala.php. I have a script to check if the first line is "lalala", if it isn't then it will replace it with "lalala". Then it will rewrite the new information back into lala.php. For some reason this doesn't work. It will simply replace the contents of the entire file with "lalala". I only want it to replace the first line with "lalala".

 

$fh = fopen("lala.php", "w") or die("Error: Cannot open file.");
$check = file("lala.php");
$lala = "lalala";

if($check[0] != $lala){
$check[0] = $lala;
$newcheck = implode("",$check);
fwrite($fh, $newcheck);
}

fclose($fh);

have u tried fopen(FILE, r+); to read and write

 

w truncates file length to 0
