是否可以在 foreach 循环内的流中更改对象元素的子字符串？所以我尝试但它不起作用。

$xml= '';

foreach ($objetcs as $object){

        str_replace('searched','replacement', $object->link);

        //then I would call a function to render my rss
        $xml .=$object->renderRSS();

}

str_replace将返回一个字符串或一个数组，它不会改变原始变量，所以你应该这样做$object->link = str_replace('searched','replacement', $object->link);if $linkispublic

尝试这个：

$xml= '';

foreach ($objetcs as $object){

        $object->link = str_replace('searched','replacement', $object->link);

        //then I would call a function to render my rss
        $xml .=$object->renderRSS();

}
