}
and php
foreach ($read_json->scorecards->batting->players as $batsmen => $val) {
if($val == 5) { // if batsman index is 5 then display his name
$name = $batsmen->name;
echo "<div>$name</div>\n";
}
}
Please help me to solve this issue.Thanks in advance.

Answer 1

I think this would suffice your requirement
http://codepad.org/XQDCKAsB
Find the code sample below as well.
$json = '{"currentOver":{"events": []},"matchString":"","currentPlayer":5,"previousOvers":[],"innings":[],"scorecards":[{"batting":{"players":[{"id":16447,"name":"Rahul Roy"},{"id":12633,"name":"Sijal Thomas"},{"id":16446,"name":"Mohammed Reza"},{"id":16509,"name":"Asif Khan"},{"id":12633,"name":"Koyel Dijesh"},{"id":16468,"name":"Shahrook"},{"id":64691,"name":"Shafiq"},{"id":6518,"name":"Ubaidulah"}]}}]}';
$arr = json_decode($json);
echo '<pre>';
$currentPlayer = $arr->currentPlayer;
echo $arr->scorecards[0]->batting->players[$currentPlayer-1]->name;

Answer 2

Try this code.
$info = json_decode('json string');
$currentPlayer = $info->currentPlayer;
$batsman = $info->scorecards[0]->batting->players[$currentPlayer];
echo "<div>{$batsman->name}</div>\n";
Also, note that arrays in PHP are zero-based. If currentPlayer index in json data is based on 1 (rare case, but it exists sometimes) you will ned to use
$batsman = $info->scorecards[0]->batting->players[$currentPlayer - 1];
to get right item from array.

Answer 3

If you just want to fix your foreach
$read_json->scorecards->batting should become $read_json->scorecards[0]->batting
if($val == 5) should become if($batsmen == 5)
$name = $batsmen->name; should become $name = $val->name;

Answer 4

You need to use json_decode and array_keys for the array keys from the json.
$json = '{ "key1" : "watevr1", "key2" : "watevr2", "key3" : "watevr3" }';
$result = json_decode ($json, true);
$keys = array_keys($result);
print_r($keys); //Array ( [0] => key1 [1] => key2 [2] => key3 )

Answer 5

In Php, You can use the code below, if you wan to fix it using foreach loop
foreach($json->entries as $row)
{
foreach($row as $key => $val)
{
echo $key . ': ' . $val;
echo '<br>';
}
}

Answer 6

please have a look following code
$json=json_decode($data)->scorecards[0]->batting->players;
foreach ($json as $key => $value) {
if($key==5){
echo $value->name ;
}
}

Answer 7

You can do it using converting JSON string to Array
$json_str = '{
"currentOver":{
"events":[]
},
"matchString":"",
"currentPlayer":5,
"previousOvers":[],
"innings":[],
"scorecards":[
{
"batting":{
"players":[
{"id":16447,"name":"Rahul Roy"},
{"id":12633,"name":"Sijal Thomas"},
{"id":16446,"name":"Mohammed Reza"},
{"id":16509,"name":"Asif Khan"},
{"id":12633,"name":"Koyel Dijesh"},
{"id":16468,"name":"Shahrook"},
{"id":64691,"name":"Shafiq"},
{"id":6518,"name":"Ubaidulah"}
]
}
}
]
}';
Decode your JSON string using "json_decode" and you get array
$json_decode_str = json_decode($json_str, true);
Now using foreach you can do anything
if($json_decode_str['scorecards']){
foreach($json_decode_str['scorecards'] as $scorecard){
$player_index = 1;
if($scorecard['batting']['players']){
foreach($scorecard['batting']['players'] as $player){
if($player_index == 5){
echo $player['name'];
}
$player_index++;
}
}
}
}
Maybe this one help you :)
