Thanks george,
But i want to read for multiple such files and i have many other keywords match which should be deleted.The array of keywords are ("[","TYP","P_MPP","I_MPP","V_MPP","T=","FIT","INTENSITAET");
and i aslo want to write back the reamaining lines after deleting into the same file but not in a different file.

Hi,
Do you just want to delete the lines containing '[' or 'TYP', or '[' AND
'TYP'?
So your block would read:
SUBSTRATNAME=S112
PIXEL=5
OPERATOR=Zi
KOMMENTAR=dunkel
INTENSITAET=1000.000000
DATUM=03.01.2005
UHRZEIT=11:22
MESSUNG=SWEEP_UI
correct???
I would do the following:
$filename="myfile.txt";
$target="myfile2.txt";
$handle = fopen ($filename, "r");
while (!feof ($handle)) {
$buffer = fgets($handle, 8192);
if (substr($buffer,0,1)!=='[' && substr($buffer,0,3)!=='TYP'){
$hf = fopen($target, 'a');
fwrite($hf, $buffer);
fclose($hf);
}
}
fclose ($handle);
That should do the trick.
