PHP 致命错误:仅在 Eclipse 中调用未定义函数 json_decode()

【中文标题】PHP 致命错误:仅在 Eclipse 中调用未定义函数 json_decode()【英文标题】:PHP Fatal error: Call to undefined function json_decode() ONLY in eclipse 【发布时间】:2016-08-19 23:57:15 【问题描述】:

感谢您先查看我的问题!我已经尝试过类似的帖子php Fatal error: Call to undefined function json_decode() 并搜索了很多,但我仍然无法解决我的问题。

目前,该问题仅发生在 Ecpise 中。 php 与终端中的 json_decode() 配合得很好。

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);
?>

我收到错误:“PHP 致命错误:调用未定义函数 json_encode()”。

但是,当我在终端中运行代码文件时,它运行良好。所以我猜这可能是由 Eclipse 中的 PHP 解释器引起的。然后我发现我同时拥有 usr/bin/php 和 user/bin/php5,我都尝试了,但它们都没有在 eclipse 中工作:

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

php 在哪里:

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

php--版本:

真诚的

【问题讨论】:

【参考方案1】:

您需要检查 PHP 加载的配置文件,因为安装了扩展名并不意味着它不能被禁用。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

尤其是这个:

/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)

编辑

我刚刚意识到,您在问题中作为 php 状态信息包含的内容可能与您的 Eclipse 使用的 PHP 不同。为了确保我们没有看到不同的东西,运行这个脚本via eclipse

<?php
phpinfo();

看看你在那里得到了与 JSON 相关的内容(如果列出了 JSON 扩展)。还要检查 php.ini 列出的内容。

【讨论】:

感谢您的快速回复!但我找不到“json”和“zend_extension”。在 php.ini 中。和 /etc/php5/cli/conf.d/05-opcache.ini : "; php ZendOpcache 模块的配置 ; priority=05 zend_extension=opcache.so" ; 10-pdo.ini :"; php PDO 模块的配置;优先级=10 扩展=pdo.so"; 20-readline.ini :"; php readline 模块的配置;优先级=20 extension=readline.so"; 20-json.ini:"; php json 模块配置;priority=20 extension=json.so". 现在大多数扩展配置都在conf.d,所以你需要检查/etc/php5/cli/conf.d/20-json.ini文件,因为这似乎是与json扩展相关的。 是的。 “;php json模块的配置;priority=20 extension=json.so”是20-json.ini文件中唯一的内容。期待您的回复,并感谢一百万! ; 在与extension=json.so 的行首吗?似乎不是你的日志告诉json support =&gt; enabled.... 不,没有“;”在 extension=json.so 的行首【参考方案2】:

最后,我发现问题是我以某种方式安装了两个 PHP。因此,当我通过“sudo apt-get remove php5-json”卸载其中一个并在 Eclipse 中找到另一个可执行的 PHP 文件后,问题就解决了!

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!

【讨论】:

【参考方案3】:

勾选“Window->Preferences->Installed PHPs”复选框“Use system default php.ini configuration”必须启用。 而且我必须在我的 Ubuntu 上设置“apt install php-json”。
