This is an example for deleting N lines after an occurence of particular string:
<?
$filename = "./result.txt";
$fd = fopen ($filename, "r");
$query_str="Memory";
$m_line=5;$tmp_line=0;$line=0;
$m_filename = "./result2.txt";
$m_fd = fopen($m_filename, "w");
while (!feof ($fd))
{
$buffer = fgets($fd, 4096);
$pos = strpos ($buffer, $query_str);
if ($pos === false and $line==0)
{
fputs ($m_fd,$buffer);
}
else
{
if ($tmp_line < $m_line)
{
$tmp_line = $tmp_line + 1;
$line = 1;
}
else
{
$line = 0;
}
}
}
fclose($fd);
fclose($m_fd);
copy("./result2.txt","./result.txt");
?>
