php str_replace和对象

Question

是否可以更改对象元素的子字符串 在foreach循环内部的流程？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();

}

Answer 1

str_replace将返回字符串或数组，它不会更改原始变量，因此如果$object->link = str_replace('searched','replacement', $object->link);为$link

，您应该public

Answer 2

试试这个：

$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();

}

Answer 3

尝试：

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