json_decode causes failures.

I am new to Zephir so I apologise if this is one of those 'should have read the docs' situation: Issue: When I use json_decode() within a .zep file the build fails with ' undefined symbol: php_json_decode_ex in Unknown on line 0 '

My searches have revealed an optimizer for json_decode, but optimizers are beyond me at present! I have found no other reference to json_decode and Zephir.

This may be another clue to my problem:

Trying to use the Zephir built in functions array->merge(anotherArray) and var s = "Hello" s->length() the compiler / parser appears to work OK and installs my extension, but then I get 500 errors from Apache. Using PHP's array_merge(arrayA, arrayB) works OK, extension compiles, installs and works.

Any help appreciated.

Thanks in advance. Jonathan

I used the following sh script to install Zephir, maybe there's an issue here! :

#!/bin/bash

I have finally found a solution to the json_decode issue. Being new to linux I am not sure if it is the correct solution: JSON support was shown as being available via phpinfo(), the json extension is loaded via json.ini within the php.d directory. I commented out the extension in /etc/php.d/json.ini and added 'extension=json.so' to /etc/php.ini BEFORE any other extension. This seems to have solved the json_decode errors that I was receiving. I have further tests to do to make sure json_decode is working properly, but at least I have some progress.
