Something like:

Thanks Dave at the moment I have this code.

PHP Code:

$roadfile = fopen("road.txt", "r") or die("Unable to open file!");

$output = fread($roadfile,filesize("road.txt"));

//preg replace code to go here:
//$output = preg_replace('London', '', $output);

fclose($roadfile); 


So I am thinking with your code it will be

PHP Code:

$roadfile = fopen("road.txt", "r") or die("Unable to open file!");

$output = fread($roadfile,filesize("road.txt"));

//preg replace code to go here:
//$output = preg_replace('London', '', $output);

if(strpos($output, 'London') === false) { 
   // continue  
  //explode lines and stop on comma
} 

fclose($roadfile);
