There is a PHP function that can highlight a word regardless of case or accents, but the string returned will be the original string with only the highlighting? For example:
Function highlight($string, $term_to_search){
// ...
}
echo highlight("my Striñg", "string")
// Result: "my <b>Striñg</b>"
Thanks in advance!
What I tried:
I tried to do a function that removed all accents & caps, then did a "str_replace" with the search term but found that the end result logically had no caps or special characters when I expected it to be just normal text but highlighted.

You can use ICU library to normalize the strings. Then, look for term position inside handle string, to add HTML tags at the right place inside original string.
function highlight($string, $term_to_search, Transliterator $tlr) {
$normalizedStr = $tlr->transliterate($string);
$normalizedTerm = $tlr->transliterate($term_to_search);
$termPos = mb_strpos($normalizedStr, $normalizedTerm);
// Actually, `mb_` prefix is useless since strings are normalized
if ($termPos === false) { //term not found
return $string;
}
$termLength = mb_strlen($term_to_search);
$termEndPos = $termPos $termLength;
return
mb_substr($string, 0, $termPos)
. '<b>'
. mb_substr($string, $termPos, $termLength)
. '</b>'
. mb_substr($string, $termEndPos);
}
$tlr = Transliterator::create('Any-Latin; Latin-ASCII; Lower();');
echo highlight('Would you like a café, Mister Kàpêk?', 'kaPÉ', $tlr);

you can try str_ireplace
echo str_ireplace($term_to_search, '<b>'.$term_to_search.'</b>', $string);
