PHP BLOB字段数据与原始数据不同

Question

I have a weird issue when dealing with a BLOG field coming from an iOS NSData source. I pass it through to a PHP web service.

The original source has a length of 10159. The PHP source has a length of 10159 when it gets to the web service. I enabled General Logging in MYSQL and verified that the prepared statement is actually getting original bytes that were sent from the client.

Here is the PHP code:

//call the stored procedure
$stmt2 = $this->db->prepare("CALL sp_event_master_create(?,?,?,?,?,?,?,?,?,?,?,?, @event_master_id)");
$stmt2->bind_param('sssssssbsssi',   
    $event_name,
    $event_location,
    $mysql_start_date,
    $mysql_end_date,
    $event_website,
    $event_facebook,
    $event_description,
    $event_image,
    $event_contact_name,
    $event_contact_number,
    $event_contact_email,
    $event_app_user_id);

//set the image to be uploaded
$stmt2->send_long_data(7, $event_image);

When I query the BLOB field on the getById web service call, the size returned back to the client has ballooned to 22,325. The first bytes of the return look nothing like the original bytes sent to the database.

I tried to use base64_decode the blob returned but that didn't work. I know that I must have a setting incorrectly setup for the field or the database.

PHP VERSION : 5.5.3

MYSQL VERSION : 5.5.34

The issue seems to actually be in RESKIT not in PHP or MYSQL. I converted the field to a MEDIUMTEXT and the data that is in the database is correct. I can see on the web service calls that the JSON data matches what was sent.

I have posted on the google group for reskit: https://groups.google.com/forum/#!topic/restkit/zMh98jCdGF0
