如何从PHP stdClass对象的输出创建PHP stdClass对象

Question

I have the following as a string:

stdClass Object
(

    [createResult] => stdClass Object

       (
           [ReturnCode] => 1
       )

)

How can I take the above string and create a new stdClass Object? I'd like to get the value like this:

$rc = $obj->createResults->ReturnCode;

Answer 1

If you can change the way it outputs into something like var_export , you can afterwards use that string with eval to get it back.

Answer 2

If you can't change it (for whatever reason) and have to use the output of print_r, then you could try this recipe and see if it works for you. http://www.php.net/manual/en/function.print-r.php#93529

However, if at all possible, you should be storing data in a more portable format. You could use php's serialize => unserialize , or json_encode => json_decode , for starters.

You can also do it like this:

<?php
$s = "stdClass Object
(

    [createResult] => stdClass Object

       (
           [ReturnCode] => 1
  )

)";
$s = preg_match("/\s\[ReturnCode\] => \S+\s/", $s, $m);
echo preg_replace("/\s\[ReturnCode\] => (\S+)\s/", "$1", $m[0]);
