现在我想从中替换一些单词。所以我使用了下面写的代码：

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

但我没有得到任何结果。所以，如果我做错了什么，请帮忙。

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

尝试这个：

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

问题是您没有设置 str_replace() 函数的返回值

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

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

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

查看http://www.php.net/manual/en/function.str-replace.php上的 str_replace 文档

我不完全确定我是否理解正确，但我认为这可能是你想要做的：

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