Actually, I see I've made a small mistake in that script, here's an
updated one:
<?php
$deleteLines =
array("[","TYP","P_MPP","I_MPP","V_MPP","T=","FIT","INTENSITAET");
if($handle = opendir('.')) {
while(($file = readdir($handle)) !== false) {
// init vars
$contents = '';
if (!(preg_match('/^2005\d{4}_\d{4}\.txt$/', $file) ||
preg_match('/^2005\d{4}_\d{4}\_01_01\.txt$/',$file))){
// the filename has been rejected; move on to the next one
continue;
}
// right, we need to open the file now so we can delete the lines
$contents = file($file);
$stream = fopen($file, 'w');
// loop trough the file, examining each line
foreach($contents as $line=>data) {
$clearLine = false;
foreach($deleteLines as $delete) {
if(0 === strpos($data, $delete)) {
// string starts with one of the ToBeDeleted parts
$clearLine = true;
}
}
if(!$clearLine) {
fwrite($stream, $data, strlen($data));
}
}
fclose($stream);
}
}
closedir($handle);
?>
