JSON編碼姓名+姓氏=全名

Question

我要合併姓名和作爲全名一起LASTNAME

$record[0]["firstname"]="foo"; 
$record[0]["lastname"]="bar"; 
$record[0]["age"]="20"; 

for ($i=0; $i<3; $i++) { 

    $foobar_array[] = array(
      'fullname' => [$record[$i]['firstname'], $record[$i]['lastname']], 
      'age' => $record[$i]['age'] 

    ); 


} 

echo json_encode($foobar_array); 

我想JSON字符串顯示

[{"fullname":"foo bar ","age":"20"}] 

Answer 1

此：

$foobar_array[] = array(
    'fullname' => $record[$i]['firstname'] . ' ' . $record[$i]['lastname'], 
     'age' => $record[$i]['age'] 
); 

Answer 2

$record = [ 
    [ 
     'firstname' => 'foo', 
     'lastname' => 'bar', 
     'age' => 20, 
    ] 
]; 

foreach ($record as $r) { 
    $foobar_array[] = [ 
      'fullname' => $r['firstname'].' '.$r['lastname'], 
      'age' => $r['age'] 
    ]; 
} 

echo json_encode($foobar_array);

[{"fullname":"foo bar","age":"20"}]
