This is simple, but I don't know what to search to find my answer. Can someone please tell me in what format this data was inserted in the table ?
I want to read/insert/update it using PHP.

This is an serialized array, you can unserialize it to convert it back to the array type, and then serialize it back to string.
There is obviously a lot of debate on this being json or serialized data, but the length indicators for the upcoming string next to : clearly indicate a serialization.
$aArray = unserialize($sContents);
$sContents = serialize($aArray);
It's a serialized array
you can deserialize it with http://www.php.net/manual/de/function.unserialize.php
That looks like Json, see http://en.wikipedia.org/wiki/JSON and http://www.json.org/

I am confused on what kind of data is this. Can anyone help me on this. I am trying to make it in readable format using PHP.
a:6:{s:12:"cfdb7_status";s:6:"unread";s:9:"your-name";s:6:"Sujith";s:10:"your-email";s:21:"sudhamenon990#gmail.com";s:12:"your-subject";s:5:"Hello";s:12:"your-message";s:16:"How are you man?";s:16:"ywctm-product-id";s:4:"1840";}
Thank you in advance.
It is a serialized array. You need to unserialize it
unserialize ( string $data , array $options = [] )
unserialize() takes a single serialized variable and converts it back into a PHP value.So that you can access it using php.
I have an array with multiple items in it one of which is an already encoded json string. I'm wanting to json encode the whole array but in doing so it re-json_encodes the json and adds slashes to it. The only way I've found to fix this is to json_decode the value and then encode the whole array. I feel like this is a waste of resources though and I feel like there has to be a better way. Is doing it that way the best possible way?
Here's a sample of the array I'm trying to json_encode.
$arr = array();
$arr["var1"] = '{"test":"test"}';
$arr["var2"] = 'foo';
$arr["var3"] = 'bar';
If I don't decode the var1 first and I just encode the whole array I get a result like so
{"var1":"{\"test\":\"test\"}","var2":"foo","var3":"bar"}
Notice the slashes in the json object.
json_encode() returns a string containing the json representation of a value.
In the example, a php string is passed as one element of the array '{"test":"test"}', thus json_encode() is encoding it appropriately into json format, with escaped quotes "{\"test\":\"test\"}".
If decoding nested json is a very resource heavy task, a workaround is to use a placeholder instead of the value, {"var1":"PLACEHOLDER","var2":"foo","var3":"bar"}, and then using str_replace() to replace it.
However, simply decoding it as you described is probably a cleaner solution, if its not resource heavy.
I have a Type Length Value string:
a:4:{s:5:"value";s:4:"0.00";s:4:"type";N;s:12:"discounttype";s:10:"Percentage";s:13:"configoptions";N;}
Is it possible to convert it to PHP array or JSON string?
That kind of string could be done with unserialize() function. Also there is an article about that solving your needs here.
After it has been unserialized, it is an array. You can then convert using json_encode() function.
If you need extra help, write a comment
I have my data stored in a JSON string like these...
a:1:{s:15:"s2member_level1";s:1:"1";}
How can i read this values in mysql?
I need to know if the value "s2member_level1" is 1.
Thanks!!!
That's not JSON but a string resulted from calling serialize() in PHP. You cannot parse it easily in MySQL. If you can use PHP, use the unserialize function:
$obj = unserialize($data_from_mysql);
if ($obj['s2member_level1'] == 1) {
// more code here
}
You can convert data to JSON in PHP using the json_encode function. In a similar way, you construct an object from a JSON string using json_decode.
#Lekensteyn is correct, but you could do a like statement, although its performance would most likely be very poor. My true answer is to change how you store this information to take advantages of best performing queries.
select * from table
where column like '%s:15:"s2member_level1";s:1:"1";%';
#Lekensteyn is right about the type of this particular String, but for others, PHP has json_decode which you can use to convert a JSON object to a PHP object. It would be considerably more difficult to read such an object using MySQL only.
This is no json, but serialized data. It was probably serialized with the 'serialize' function of PHP. Try:
print_r(unserialize('a:1:{s:15:"s2member_level1";s:1:"1";}'));
... to unserialize it.
Hey can anyone tell me what datatype this is? it wont parse as i've stripped out sensitive data. Am I correct in thinking its json?

This is a serialized PHP array. Essentially, it's just a string that represents a PHP array (the a at the beginning marks it as an array).
You can get the PHP array back out of it by passing the string to the PHP function unserialize().
That is serialized data - not Wordpress specific.
Take a look into serialize(), unserialize() and OOP serialization: __sleep()/__wakeUp().
