Answer 1

我会使用 str_replace https://www.php.net/manual/en/function.str-replace.php

$string = "Year 7 Scheme of Learning – Lord of the Flies/Transactional Writing HAO";

// remove spaces and hyphen
$newString = str_replace(" - ","",$string);

// remove 1 space and hyphen
$newString = str_replace(" -","",$string);

// remove hyphen
$newString = str_replace("-","",$string);
