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

thanks for your viewing my question first! I have tried the similar post PHP Fatal error: Call to undefined function json_decode() and googled a lot, but I still cannot fix my problem.

Currently, the problem is only happening in the Ecplise. The php works well with json_decode() in Terminal.

Following are the details:

When I tried to run the code in Eclipse,

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

I got the error: " PHP Fatal error: Call to undefined function json_encode()".

However, when I run the code file in terminal, it works perfectly. So I guess it could be caused by the PHP interpreter in Eclipse. Then I found I have both usr/bin/php and user/bin/php5, I tried both, but none of them is working in the eclipse: enter image description here

My System:Ubuntu 14.04 Eclipse version:Version: Mars.2 Release (4.5.2)

whereis php:

    Finally, I found the problem is I have installed two PHP somehow. So after I uninstall one of them by "sudo apt-get remove php5-json" and find the another executable PHP file in Eclipse, then problem is solved!

    In conclusion, I think the best way to fix this kind of problem is to reinstall it! Thanks for the help from Marcin Orlowski. Good luck, guy!

    You need to check config files loaded by PHP, because the fact extension is intalled does not automatically mean it cannot be disabled. So inspect:

    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
    

    especially this one:

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

    and uncomment the zend_extension=... line in case it is commented out (or not present)

    EDIT

    I just realised that what you included in your question as php state info may not come from the same PHP your Eclipse is using. To ensure we are not looking at something different, run this script via eclipse

    <?php
    phpinfo();
    

    and see what you got JSON related there (if there's JSON extension listed). Also check what php.ini is listed.

    Check "Window->Preferences->Installed PHPs" checkbox "Use system default php.ini configuration" must be enabled. And I had to setup "apt install php-json" on my Ubuntu.
