How to "skew" search results?

[Concat]

How can I skew search results, so results start with relevant search text?

e.g.:

$complete_row_text = "Phasellus posuere sapien id sapien interdum auctor. Fusce et justo. Morbi ac arcu vitae erat viverra egestas. In orci. In rutrum purus sed erat. Cras commodo massa non tortor. Vivamus feugiat. Proin ac nisl. Proin in enim sed lorem imperdiet dapibus. Vivamus eget sem.";

$search_word = "Cras commodo";

The result should be displayed skewed like:

echo "..viverra egestas. Cras commodo massa non tortor. Vivamus feugiat. Proin ac nisl. Proin in enim sed lorem imperdiet dapibus. Vivamus eget sem.";

I don't understand how to :rolleyes:

Have I got this right?

You want to find the position of the serch term,
go back 3 sentences and show the last 2 words of that sentence,
skip the next 2 sentences,
display from the search term onwards?

Never mind. I found a way to make it work.

$complete_row_text = "Phasellus posuere sapien id sapien interdum auctor. Fusce et justo. Morbi ac arcu vitae erat viverra egestas. In orci. In rutrum purus sed erat. Cras commodo massa non tortor. Vivamus feugiat. Proin ac nisl. Proin in enim sed lorem imperdiet dapibus. Vivamus eget sem.";

// the last paramenter in substr();
$how_long = strlen($complete_row_text);

$search_word = "Cras commodo";

// the first paramenter in substr();
$position = strrpos($complete_row_text,$search_word);

echo $position . " -> ";

echo substr($complete_row_text,$position-10,200);

and now it display text like Google do 🆒

There is two other functions that could be added

function truncate_string($details,$max)
{
    if(strlen($details)>$max)
    {
        $details = substr($details,0,$max);
        $i = strrpos($details," ");
        $details = substr($details,0,$i);
        $details = $details."<b>...</b>";
    }
    return $details;
}

and

function bold($subject, $word)
        {
        $mywords = explode(" ",$word);
        for ($j=0;$j<count($mywords);$j++)
            {
            $regex_chars = '\.+?(){}[]^$';
            for ($i=0; $i<strlen($regex_chars); $i++)
                {
                $char = substr($regex_chars, $i, 1);
                $mywords[$j] = str_replace($char, '\\'.$char, $mywords[$j]);
                }
            $mywords[$j] = '(.*)('.$mywords[$j].')(.*)';
            $subject =  eregi_replace($mywords[$j], '\1<b>\2</b>\3', $subject);
            }
        return $subject;
}

the result with search word "Cras commodo" will look just like this:

[FONT="Georgia"]...sed erat. Cras commodo massa non tortor. Vivamus feugiat. Proin ac nisl. Proin in enim sed lorem imperdiet dapibus. Vivamus eget sem.[/FONT]

If you just wanted to bold the word withting a text you could have just done:

$word="test"
$text="This is my test for the word test, see"
$search=str_replace($word, "<b>".$word."</b>", $text); 
echo $search;
