replace a line in a textfile

[fragger]

Hi all,

I have a textfile with some contents (6 lines)
I "fopen" the file and want to replace the line "avail" with "unavail". The code below doesn't work. Can anyone help me ?

Thanx in advance

Olli

$comp = $destdir.$textfile;
$contents = file($comp);
$fp = fopen ($comp,"w");
for($i=0; $i<count($contents); $i++)
{
if(eregi("avail",$contents[$i]))
{
fwrite ($fp,"unavail"."\n");
}
else
{
fwrite($fp, $contents[$i]);
fwrite($fp, "\n");
}
}
fclose ($fp);

$comp = $destdir.$textfile;

$data = file_get_contents($comp);

$data = preg_replace("/(\s)avail/", "\\1unavail", $data);

$fp = fopen($comp, "w+");
fwrite($fp, $data);
fclose($fp);

try that.

Thanx ! It works 😉

You just forgot to give the preg_replace VAR a different name 😉
