發送foreach循環PHP和JSON

我不是在那裏我去錯了安靜肯定，但，當我使用這個郵件功能：發送foreach循環PHP和JSON

<?php 
function printMember($member) { 
    foreach($member as $key=>$value) { 
     echo "$key : $value <br />"; 
    } 
} 

$to = '[email protected]'; 

$subject = 'Application Form'; 

$headers = "From: " . strip_tags($_POST['req-email']) . "\r\n"; 
$headers .= "Reply-To: ". strip_tags($_POST['req-email']) . "\r\n"; 
$headers .= "BCC: [email protected]\r\n"; 
$headers .= "MIME-Version: 1.0\r\n"; 
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n"; 


$json = $_POST['parameters']; 
$json_string = stripslashes($json); 
$data = json_decode($json_string, true); 

$depCount = count($data["dependants"]); 


$msg .= "<h2>Main member data:</h2>"; 
$msg .= printMember($data["mainmember"]); 

$msg .= "<h2>There are $depCount Dependants</h2>"; 

foreach ($data["dependants"] as $index => $dependant) { 
    $msg .= "<h2>Dependant $index</h2>"; 
    $msg .= printMember($dependant); 
} 

mail($to, $subject, $msg, $headers);

Main member data: 
There are 3 Dependants 
Dependant 0 
Dependant 1 
Dependant 2

代替（如顯示在控制檯）：

Main member data: 
name : name 
surname : surename 
id : 6110190027087 
age : 51 
gender : Female 
townofbirth : george 
email : [email protected] 
contact : 0512148615 
passport : 1111111111111 
postal : test 
postal_code : 4545 
residential : test 
residential_code : 4545 

There are 1 Dependants 
Dependant 1 
name : dep1 
surname : dep1 
id : 8202255133088 
age : 30 
gender : Male 
townofbirth : dep1 
cell : 0145264448 
email : dep1 
passport : 2222222222222 
relationship : parent

這裏的JSON：

{ 
    "mainmember": { 
     "name": "name", 
     "surname": "surename", 
     "id": "6110190027087", 
     "age": "51", 
     "gender": "Female", 
     "townofbirth": "george", 
     "email": "[email protected]", 
     "contact": "0512148615", 
     "passport": "1111111111111", 
     "postal": "test", 
     "postal_code": "4545", 
     "residential": "test", 
     "residential_code": "4545" 
    }, 
    "dependants": [ 
     { 
      "name": "dep1", 
      "surname": "dep1", 
      "id": "8202255133088", 
      "age": "30", 
      "gender": "Male", 
      "townofbirth": "dep1", 
      "cell": "0145264448", 
      "email": "dep1", 
      "passport": "2222222222222", 
      "relationship": "parent" 
     } 
    ] 
}

我沒有得到這個答案：Parsing Duplicatable Form's JSON data to PHP for Mail

但只是沒有實際的郵件..

任何幫助，不勝感激

您是doint'echo'，而不是返回。檢查我的答案 –

的問題是在printMember()功能，你正在做echo和不會返回任何東西：更新您的printMember功能，如下所示：

function printMember($member) { 
    foreach($member as $key=>$value) { 
     //Fill the aux string first 
     $str.= "$key : $value <br />"; 
    } 
    //string that will be added to $msg variable inside the loop 
    return $str; 
}
