[GSoC] Passing a json string as input to an applciation in PHP-SDK

[Nadeem Anjum]

Hello Everyone,

I have registered an application (A Genapp Module) which takes a json
string as input. I am using PHP client samples', createExperiment Method

I use the follopwing code:

$input->value = $json;

where $json has value

"{\"input1\\":\\"0\\",\\"input2\\":\\"1\\",\\"input3\\":\\"on\\",\\"_logon\\":\\"\\",\\"_project\\":\\"\\",\\"_uuid\\":\\"c9894860-f236-11e3-8708-19a98ecc24ae\\",\\"_base_directory\\":\\"/var/www/html/nadeemtest/results/5399ad3f791f5\\",\\"_udphost\\":null,\\"_udpport\\":37779,\\"resourcedefault\\":\\"local\\"}";

However, the in response received, $input->value gets changed to

 
"{"input1":"0","input2":"1","input3":"on","_logon":"","_project":"","_uuid":"c9894860-f236-11e3-8708-19a98ecc24ae","_base_directory":"/var/www/html/nadeemtest/results/5399ad3f791f5","_udphost":null,"_udpport":37779,"resourcedefault":"local"}"

which being malformed, does not give me the expected output.

The response is given below:

Any ideas on how to deal with this situation will be appreciated.
