PHP致命错误：仅在eclipse中调用未定义的函数json_decode（）

Question

感谢您先查看我的问题！我尝试了类似的帖子PHP Fatal error: Call to undefined function json_decode()并搜索了很多内容，但我仍然无法解决问题。

目前，问题只发生在Ecplise上。 php适用于终端中的json_decode（）。

以下是详细信息：

当我尝试在Eclipse中运行代码时，

<?php
$arr = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5);
echo json_encode($arr);
?>

我收到了错误：＆＃34; PHP致命错误：调用未定义的函数json_encode（）＆＃34;。

然而，当我在终端中运行代码文件时，它完美地运行。所以我想这可能是由Eclipse中的PHP解释器引起的。然后我发现我有usr / bin / php和user / bin / php5，我试过两个，但是没有一个在eclipse中工作：

我的系统：Ubuntu 14.04 Eclipse版本：版本：Mars.2发布（4.5.2）

whereis php：

php: /usr/bin/php /usr/bin/X11/php /usr/share/php /usr/share/man/man1/php.1.gz

php --version：

Answer 1

您需要检查PHP加载的配置文件，因为安装的事实扩展并不意味着它无法被禁用。所以检查：

Loaded Configuration File => /etc/php5/cli/php.ini
Scan this dir for additional .ini files => /etc/php5/cli/conf.d
Additional .ini files parsed => /etc/php5/cli/conf.d/05-opcache.ini,
/etc/php5/cli/conf.d/10-pdo.ini,
/etc/php5/cli/conf.d/20-json.ini,
/etc/php5/cli/conf.d/20-readline.ini

特别是这一个：

/etc/php5/cli/conf.d/20-json.ini

并取消注释zend_extension=...行，以防它被注释掉（或不存在）

修改

我刚刚意识到你作为php状态信息包含在你的问题中的内容可能不是来自Eclipse使用的相同PHP。为确保我们不会查看不同的内容，请运行此脚本通过eclipse

<?php
phpinfo();

并查看您在那里获得的JSON相关内容（如果列出了JSON扩展名）。另请查看列出php.ini的内容。

Answer 2

最后，我发现问题是我以某种方式安装了两个PHP。所以在我卸载其中一个＆＃34; sudo apt-get删除php5-json＆＃34;并在Eclipse中找到另一个可执行的PHP文件，然后问题解决了！

总之，我认为解决此类问题的最佳方法是重新安装它！感谢Marcin Orlowski的帮助。祝你好运，伙计！

Answer 3

选中“窗口->首选项->已安装的PHP”复选框，必须启用“使用系统默认的php.ini配置”。 而且我必须在Ubuntu上设置“ apt install php-json”。
