i have set json data. in have return json key , value pair in php. used json follows 

[{   "id": "1995",   "name": "banahatti" }, {   "id": "5074",   "name": "kolhapur(maharashtra)" }, {   "id": "2356",   "name": "bmbur" }, {   "id": "906",   "name": "ammla" }, {   "id": "536",   "name": "puttur" }, {   "id": "1308",   "name": "poogolam" }, {   "id": "1217",   "name": "sarangpur" }, {   "id": "826",   "name": "hiriyur" }, {   "id": "24911",   "name": "himmatnagar" }, {   "id": "3993",   "name": "podili" }]

in json values , have search , json ,if give name value starting b means have result json follows

   [{       "id": "1995",       "name": "banahatti"     },      {       "id": "2356",       "name": "bmbur"     }]

how can able achieve in php.

php knows nothing json, convert array , use array_filter, , convert json. not super effecient, better trying regex. following:

$arr = json_decode($json, true); $res = array_filter($arr, function($val) {     return substr($val['name'],0,1) == 'b'; }); $newjson = json_encode($res);
