php - Find exact string inside a string

Question

I have two strings "Mures" and "Maramures". How can I build a search function that when someone searches for Mures it will return him only the posts that contain the "Mures" word and not the one that contain the "Maramures" word. I tried strstr until now but it does now work.

Answer 1

You can do this with regex, and surrounding the word with word boundary

preg_match("~Mures~",$string)

example:

$string = 'Maramures';
if ( preg_match("~Mures~",$string) )
  echo "matched";
else
  echo "no match";
