    The reason it did not work is because of your php version. try this
    PHP Code:
    $message = 'google yahoo,  googler googleyahoosgoogle';

    $word = array(
    'google',
    'yahoo'
    );

    $link = array(
    'go*gle',
    'yah*o'
    );

    $combine = array_combine($word, $link);

    $exp = '/\b('. implode('|', $word).')\b/';

    $message = preg_replace_callback($exp, function($match) use ($combine){
        return     $combine[$match[1]];
    },     $message);

    echo     $message; 
    I dont think this is possible

    googleg*oglegoogle
    yahooyah*oyahoo

    Because your first requirement is not to replace words like "googler" and in your second requirement is replace words like "googler".

    If you want to replace all the words remove the two '\b's in $exp.
