今、私はそれからいくつかの単語を置き換えたいと思います。だから私は以下に書かれたコードを使用しました：

    if(strstr($sql, "href='")){
        str_replace("href='", 'href="', $sql);
$data = $sql;
fwrite($handle, $data);
    }

しかし、私は何の結果も得られませんでした。ですから、私がやったことが何か間違っている場合は助けてください。

$sql = str_replace("href='", 'href="', $sql);

これを試して：

echo preg_replace("/(class|href)='([^']*)'/",'$1="$2"', $sql);

問題は、str_replace（）関数の戻り値を設定しないことです。

if(strstr($sql, "href='")){

    $sql=str_replace("href='", 'href="', $sql);

    $data = $sql;
    fwrite($handle, $data);
}

http://www.php.net/manual/en/function.str-replace.phpでstr_replaceのドキュメントを確認してください

私が正しく理解したかどうかは完全にはわかりませんが、これはあなたがやろうとしていることかもしれないと思います。

if(strpos($sql, "href='") !== false) ){
    str_replace("href='", 'href="', $sql);
$data = $sql;
fwrite($handle, $data);
}
