如何在 PHP 中修剪对象属性? [英] How to trim object properties in PHP?

问题描述

我有一个对象 $obj as

$obj->{' Property1'} = " value1";
$obj->{'Property2 '} = "value2 ";

我想把这个对象 $obj 作为

I want to get this object $obj as

$obj->{'Property1'} = "value1";
$obj->{'Property2'} = "value2";

我可以使用

foreach($obj as $prop => &$val)
{
     $val = trim($val);
}

但是这样做(如下)会导致错误

but doing this (below) causing an error

foreach($obj as &$prop => &$val)
{
     $prop = trim($prop);
     $val = trim($val);
}

请告诉解决方案.提前致谢.

Please tell a solution. Thanks in advance.

推荐答案

对大安回答的一点评论.在他的情况下，如果 $obj 有多个属性，脚本将陷入无限循环.所以一个工作代码看起来像这样.

A little comment to Daan's answer. In his case script will fall into infinite loop if $obj have more than one property. So a working code looks like this.

<?php
$obj = new stdClass;
$obj->{' Property1'} = " value1";
$obj->{'Property2 '} = "value2 ";

$newObj = new stdClass;

foreach($obj as $prop => $val)
{
     $newObj->{trim($prop)} = trim($val);
}

$obj = $newObj;

unset($newObj);

var_dump($obj);
