[RESOLVED] Special Characters

[alfoxy]

I'm trying to spot non-standard characters in a text file.
I want to print out the offending lines.

I have this code but it just prints out all of the lines regardless of whats in it.
Am I missing something?

$handle = @fopen("some.txt", "r");
$count = 0;
if ($handle) {
    while (!feof($handle)) {
        $input = fgets($handle, 4096);  

		$output = preg_replace("/[^A-Za-z0-9 ]/","XXXXX",$input);
		if (preg_match("@XXXXX@", $output))
		{echo "Found Crap at line $count - $input <BR>";}

	$count++;
}
fclose($handle);
}

My Text file has this in it

Alan Fox
ZenaRyle
Alán Fox
Bob Smith
James A`on
Bob Marley

Any help would be greatly appreciated ..... or a different way of doing it!

I suggest something along these lines:

$lines = file('some.txt');
$line_count = 1;
foreach ($lines as $line) {
    if (preg_match('/[^A-Z0-9 ]/i', rtrim($line))) {
        echo "Found invalid input at line $line_count - $line<br />\n";
    }
    ++$line_count;
}

rtrim() is needed since you do not count newline sequences as part of the input.

Nice one!

Very neat code and worked perfectly.

Thanks laserlight!
