How to find the end of a word using strpos()

I'm getting an address input as one long string as opposed to name, address, city, state and zip. I split most of it up, besides for between the address and the city. So I want to search for any street type name (court, road, street, avenue, etc) and then split the string at the end of the word. Then I will be left with the address and city separate.

strpos() only gives me the position of the beginning of the keyword, I want it to split at the end of the keyword. For example this is where I'm up to:

John Doe
1 Main Street Anytown
NY
00000

I want to split between Street and Anytown. And this address won't be static, there may be more words etc.

Another idea would be a function that automatically splits a string into different fields. Someone told me that in some countries the postal service has an API that does it. Does USPS have such a thing? Their site doesn't indicate it.

You can use explode function, which split a string using keyword and return an array of strings. Example of using explode: 

$str = '1 Main Street Anytown';        
$array_of_string = explode('street',$str);

Then $array_of_strings[0] will contains 1 Main and $array_of_strings[1] will contains Anytown

Actually what you should do is searching for multiple needle in haystack, summing position and length of needle. 

function strpos_street($string){
    $types = [
   'court', 
   'road', 
   'street', 
   'avenue' 
  ];
  foreach($types as $t){
      $pos = strpos(strtolower($string), strtolower($t));
      if($pos === false) continue;
      else return $pos + strlen($t) - 1;
  }
  return -1;
}

echo strpos_street($string);

Some Tips:

  • Consider case sensivity
  • You may use explode function in a same iterative way
  • I'm not sure but there may be some addresses which contains both "street" and "avenue" words

It seems that you're trying to search in reverse as strpos gives position of a string starting from the beginning by default, you will need to set the offset to -1 and subtract from strlen.

i.e.

strlen($address) - strpos($address, 'Anytown', -1) - 1;
//search from reverse and output position starting from reverse

However as pointed out in the comments, this may not the best approach for the problem you're trying to sovle.

You could do something like this.

$word = "Street"

$pos = strpos($word, $address);
if ($pos !== false) {
    $pos += strlen($word) - 1;
    ...
}

Depending on how many different words to match there are, using regex might work better than using string functions.
