Finding particular words in string

Question

I want to search the string which contains Rathi 25mm but I don't want to use the complete word to search .How can i do the search using specific words?

Rathi Stelmax 500 25 mm in stripos

   <?php
    $title='Rathi Stelmax 500 25 mm';

    if (stripos(strtolower($title), 'Rathi  25 mm') !== false)
    { 
      echo 'true';
    }
    ?>

Answer 1

There are a few ways to do this. Using your current approach you can run multiple striposs in the conditional to confirm each word is there:

$title='Rathi Stelmax 500 25 mm';
if (stripos(strtolower($title), 'Rathi') !== false && stripos(strtolower($title),  '25 mm'))
    { echo 'true';
    }

You also could use a regex such as:

/Rathi.*25 mm/
