open file, surch for entry and replace

Anon

Hello, i like to open a File -> surch for a number -> if the number exist replace the number with XXXXX, if the number not exist give out an error.
I have this setup in perl but i dont find the right funktions in php. The Perl script look like this:
if($continue) {
$pid_found = 0;
open(File,"$pinfile.dat");
flock(File,$lock);
while(<File>) {
chop($);
if($ eq "$pid_number") {
$pid_found = 1;
$ = "xxxxxxx";
}
$reprint = "$\n";
push(@reprint,$reprint);
}
flock(File,$unlock);
close(File);
if(!$pid_found) {
$push = "Error!";
push(@problems,$push);
undef($continue);
}

how can i implement this one in php i try allready:
$fp = fopen("pidfile","w+");
$line = "$pid_number";
if ($line = substr($line, 0, strlen($line) - 1)) {
i dont know what i have to place here ?
} else {
include("error.inc");
}

thanks in advance for your suggestions

Hi,
I am looking to do the same thing... but have run into a problem. It won't replace the number if there is something imediatly after it. E.g. 123344355G then it will not replace the number. But if 123344355 is there it will... y?

Thx for any input!

Best regards

Hey :-)
I figured it out, but the problem is that something is going wrong in the str_replace command I am using, somehow if it read a <VirtualHost xxx.xxx.xxx.xxx> directive, it won't replace the ip adresse since it has a '>' right after the ip adresse. And really it makes no sense. Try looking over this code:
$serverip = "$SERVER_ADDR";
$file = fopen("/etc/httpd/conf/vhosts/Vhosts.inc", "r");
$newfile = fopen("/etc/httpd/conf/vhosts/newvhosts.conf","w");
while (!feof ($file)) {
$buffer = fgets($file, 4096);
$ip = strstr($buffer, '213.112');

	if ($ip){
	$newip = str_replace(">","",$ip);
	$tmpbuffer = str_replace($ip,$serverip,$buffer);
	$newbuffer = "$tmpbuffer>\n";
}
else {
	$newbuffer = $buffer;
}
echo $newbuffer;
$out = fwrite($newfile, $newbuffer);
}
$close1 = fclose($file);
$close2 = fclose($newfile);
