PHP:可捕获的致命错误:类stdClass的对象无法转换为字符串 [英] PHP: Catchable fatal error: Object of class stdClass could not be converted to string

问题描述

我得到以下转储&运行附加代码时发生错误.我感到困惑的是，$ procID似乎以字符串形式返回，但是一旦我尝试再次传递它，它就是一个对象?我如何获得它作为/保持字符串?谢谢.

I get the following dump & error when running the attached code. What I'm confused by is that $procID appears to be returned as a string, but as soon as I attempt to pass it again, its an object? How do I get it to be/stay a string? Thanks.

object(stdClass)#2 (1) {
["processId"]=> string(13)
"Genesis114001" }  string(311)
"Genesis114001" string(293) " Genesis

推荐答案

无论$client->start()方法返回什么，都将其键入为对象.您可以使用->运算符访问对象的属性:

Whatever the $client->start() method is returning, it is typed as an object. You can access the properties of the object using the -> operator:

$procID = $client->start(array("prefix"=>"Genesis"));

...

$exchange = $client->exchangeOptions(array("processId"=>$procID->processId));

这可能是一个数组，但是正在输入一个对象.因此，您最终得到了 stdClass .

This was probably an array, but is getting typed into an object. Thus, you end up with the stdClass.

另一种(可能更好)的方法是键入return.这样，您就不必为稍后作为参数传递而创建新的数组:

Another (and possibly better) way to do this is to type the return. That way, you don't have to make a new array for later passing as argument:

$procID = (array) $client->start(array("prefix"=>"Genesis"));

...

$exchange = $client->exchangeOptions($procID);
$end = $client->stop($procID);
