Exclude Text from the out put using printf

[MPG Radio]

I would like to exclude words from the output of printf, I think this is the correct way to go about it but the page breaks and data disappears, any suggestions thank you.

function outputPlaylist($playlist) {
	$entries = parse_m3u($playlist);
	echo "<pre>\n";
		$iDontWant1="imm/"
		$iDontWant2="bla2"
		$iDontWant3="bla3"
	foreach($entries as $entry) {
	
		if($entry->Artist == $iDontWant1 || $entry->Artist == $iDontWant2 || $entry->Artist == $iDontWant3) continue; 	
	
	printf("\"%s\" by %s!\n", $entry['title'], $entry['artist']);
	}
	echo "</pre>";

the expected output should be "British" by After Alice!
not "British" by imm/After Alice!
