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");
}
