simplexml_load_string 在服务器 不可用，求大神解答！谢谢！
$xml = simplexml_load_string($string);print_r($xml);
在服务器运行报500错误，
回复讨论(解决方案)
echo 1;$xml = simplexml_load_string($string);print_r($xml);
如果前面加个输出 就不报500，可以输出1；
请问该怎么解决？
$string 是什么？
$string 是什么？
<?php$string = <<<XML<?xml version='1.0'?><document> <title>Forty What?</title> <from>Joe</from> <to>Jane</to> <body> I know that's the answer -- but what's the question? </body></document>XML;echo 1;$xml = simplexml_load_string($string);print_r($xml);
无论如何，调试时是一定要打开 php 的错误显示功能的（别自己个自己找麻烦）
也不要屏蔽任何错误检查

这是服务器上php的扩展，
我在本地代码是没有问题的，传服务器就有问题，
服务器php版本是7 本地是5.6

请问是这个吗？
我用的是phpstorm 刚才把检查错误都打开了，没有报错误。

我觉得可能是我服务器哪里配置有问题，可是又不知道从哪下手。
当然时可能的，但总是要看到错误信息才能有针对性的处理

我把php.ini 里面的display_errors设成On了，页面还是报500错误，没有打印错误

知道问题了，报错说 找不到这个方法

刚才考虑是不是SimpleXML 扩展库的问题，查了一下SimpleXML 是php的内置扩展，应该不需要配置吧。
php7 是有的 http://php.net/manual/zh/function.simplexml-load-string.php
看看是否拼写错误

首先我用php -m 看一下php加载的模块
有SimpleXML
然后 我检查是不是拼写错误，拼写没问题
还是报错
这会是什么原因造成的呢？

你用纯文本方式将那行代码再打一遍
最好不要在 IDE 里打，至少是关闭输入法（最近看到好多代码错是编辑器造成的）
