How to get the substring between two substrings in PHP

Answer 1

function SubstringBetweenTwoSubstrings($str, $suba, $subb) {
    $posA = strpos($str, $suba);
    $posB = strrpos($str, $subb);

    if ($posA === false) {
        return "";
    }

    if ($posB === false) {
        return "";
    }

    $indexEndSuba = $posA + strlen($suba);
    if ($indexEndSuba >= $posB) {
        return "";
    }

    return substr($str, $indexEndSuba, $posB - $indexEndSuba);
}

$str = "PHP C#:C C++:Java:Python";

echo SubstringBetweenTwoSubstrings($str, "C#", "Java");
