 +======Synopsis:======
 +[[json_implode]](<<var>>)
 +
 +======Technical:======
 +This function serialises an assign variable structure into a [[http://json.org/|JSON]] string.
 +
 +All sub-structures are stored as JSON sub-objects, and all assign values are stored as JSON string values.  If a part of the structure is both a sub-structure and has an assign value, the sub-structure is stored. Only global assign structures can be serialised.
 +
 +An assign variable structure can be losslessly round-tripped through [[json_implode]] and [[json_explode]], so this function is a good way for a script to serialise state to a file and reconstruct it later.
 +
 +If the function fails, an empty string is returned.
 +
 +======Returns:======
 +|<<string>>|The JSON serialised form of the structure <<var>>.|
 +|<<empty>>|The function failed (probably because <<var>> is not a structure).|
 +
 +======Examples:======
 +
 +  @ foo[client] = [EPIC]
 +  @ foo[details][description] = [EPIC rocks!]
 +  @ foo[details][protocol] = [IRC]
 +  @ foo[details][port] = 6667
 +  
 +  echo $json_implode(foo)
