What : am I doing wrong? Your if statement is wrong. You can't compare an array with a string. And your $content_array is not guaranteed to exist when it reaches your print() statement. You can test for existence with is_array(). But you already have this knowledge via your $city_found variable. Use it. Here's a revision (untested): $city = "Ipswitch"; $content = fopen("content.txt", "r"); $city_found = false; while (!feof($content)) { $my_line = fgets($content, "r"); $content_array = explode("\t",$my_line); if ($content_array[0] == $city) { print("Matched on $content_array[0]"); $city_found = true; break; } } if ($city_found) { print("$content_array[0]<br>\n"); }
