Converting a php array to a unicode json -

i need convert dynamic array following format. posting sample

{u'v2':{0:u'no',1:u'yes'}, u'v3':{1:u'maybe',3:u'almost'}} 

this did:

$vallabels = array();  $vallabeltemp1 = array();  $vallabeltemp2 = array();   $vallabeltemp1['v2'][0] = 'no';  $vallabeltemp1['v2'][1] = 'yes';  $vallabels = $vallabeltemp1;    $vallabeltemp2['v3'][0] = 'maybe';  $vallabeltemp2['v3'][1] = 'almost';  $vallabels = $vallabeltemp2; 

when write above in text file:

fwrite($fh,json_encode($vallabels) . "\n");

i following output:

{"v2":["no","yes"],"v3":["maybe","almost"]} 

i dun want above format. plus need affix 'u' represent unicode. not sure how can format. advance thanks.

you can this:

<?php  $vallabels = array(   'v2' => array('1' => 'yes', '0' => 'no'),    'v3' => array('1' => 'maybe','3' => 'almost') );  echo json_encode($vallabels); 

output:

{"v2":{"1":"yes","0":"no"},"v3":{"1":"maybe","3":"almost"}} 

nb: need revert (this doesn't matter in json result) v2 data otherwise php kind of smart type convertion , loose indices.
