Question

正如大多数人都知道的那样，我在使用for循环和if语句发送批量短信时遇到了问题。但是我已将查询减少到以下内容。我只使用AND并重复每个免疫日期的查询

    $getnumbers="SELECT
    guardian_records.First_Name,
    guardian_records.ID, 
    guardian_records.Cellphone_Number,
    children_records.Child_First_Name,
    children_records.Guardian_ID,
    children_records.ID,
    immunization_records.child_ID,
    immunization_records.First_Immunization_Date,        
FROM
    guardian_records,
    children_records,
    immunization_records
WHERE
    guardian_records.ID = children_records.Guardian_ID
    AND children_records.ID = immunization_records.child_ID
    AND immunization_records.First_Immunization_Date = CURDATE()";


$check =  mysql_query($getnumbers); 
$found =  mysql_num_rows($check);  
$details=mysql_fetch_assoc ($check);
$date1=$details['First_Immunization_Date']; 
$todays_date = date("Y-m-d"); 
$today = strtotime($todays_date);    
$immunization_date1 = strtotime($date1);

if($immunization_date1 == $today) 

for($counter=0;$counter<$found;$counter++)
{
 $date  = $date1; 
 $shots = "Polio and Diptheria";    

$cellphonenumber=$details['Cellphone_Number']; 
$childname=$details['Child_First_Name']; 
$parentname=$details['First_Name'];
$msg="Dear $parentname, your child $childname is due for $shots shots on $date which is today. Message sent by Maisha Reminder System";
$encmsg=urlencode($msg);  

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"http://localhost:13013/cgi-bin/sendsms?username=Maisha&password=m123456&to=$cellphonenumber&text=$encmsg");
curl_exec ($ch);
curl_close ($ch);
} 
}

我这样做的方法是，对于每次可能的免疫，我在同一页面中重复上述代码四次。但是，PHP不执行整个语句。它只会使第一个堆栈停止。例如，使用上面的示例代码，它只执行此位并省略其余代码，这与上面的代码完全相同，并带有相关更改

有没有办法确保PHP执行所有给定的语句。如果条件满足，FOR循环或IF语句是否阻止执行所有语句？所有帮助表示赞赏。

假设一个Guardian可以拥有多个ImmunizationIds，并且您想要向特定的电话号码发送单个短信，您可以采取以下方法：

$guardians = array();

while($row = mysql_fetch_array($yourResultSet)){
    if(isset($guardians[$row['Cellphone_Number']])){  //Make sure that your phone number has been initialized 
        $guardians[$row['Cellphone_Number']] .= "Text too add to message for this immunization";
    }else{
        $guardians[$row['Cellphone_Number']] = "Text too add to message for this immunization";
    }
}


foreach($guardians as $phoneNumber => $textMessage){
    sendMessage($phoneNumber, $textMessage); //where sendMessage is the function you use to send the text message
}

你也可以用OO方式做到这一点，但这应该足以让你开始。当然，如果邮件的结尾超过140个字符，您还需要确保在“sendMessage”中进行完整性检查，但这不是此问题的一部分。

PHP不执行所有给定的语句
