How to replace the last occurrence of a substring in a string with PHP

Answer 1

function replace_last_occurrence($s, $subs, $replace) {
    $pos = strrpos($s, $subs);

    if ($pos === false) {
        return $s;
    }

    $s = substr_replace($s, $replace, $pos, strlen($subs));

    return $s;
}

$s = "php c++ c php c# java golang php nodejs";

$s = replace_last_occurrence($s, "php", "python");

echo $s;



/*
run:

php c++ c php c# java golang python nodejs

*/
