PHP在Foreach循环中运行卷曲函数

Question

I have to send out SMS in multiples of 150 batch per CURL post. Here is my code,

$mobiles = "9844700001,9844700002,9844700003,9844700004;9844700005
 9844700006,9844700007,9844700008,9844700009,9844700010,.... upto 1000 numbers"
$rmobiles = preg_split('/[\ 
\;\:\,]+/', $mobiles, -1, PREG_SPLIT_NO_EMPTY);
if(count($rmobiles) <= 1000){
    foreach($rmobiles as $key => $value){
        if ($key % 150 == 0) {
            //Generate a new random ID
            $randno = rand(0,10000);
        }
        $this->addtoDB("00000", $value, $randno);
    } 
    return $this->sendmsms($randno);
} else {
    echo "error, max 1000";
}

Since sendmsms function is outside the foreach loop, it only sends out the last batch with the random number and if I include sendmsms function within foreach loop then the function will run as many mobile numbers are there.

How should I able to run sendmsms function based on generated randno and so that my curl function sendmsms will run properly and generate db records genuinely.

Edit

I again tried like this, but its inserting single record in my DB.

    foreach($rmobiles as $key => $value){
        if ($key % 150 == 0) {
            //Generate a new random ID
            $randno = rand(0,10000);
        }
        $this->addtoDB("00000", $value, $randno);
        if ($key % 150 == 0) {
            return $this->sendmsms($randno);
        }
    } 

Edit 2

I even tried creating array for randno. But only first batch is going, not the all 7 batches.

    $arr = array();
    foreach($rmobiles as $key => $value){
        if ($key % 150 == 0) {
            //Generate a new random ID
            $randno = rand(0,10000);
            $arr[] = $randno;
        }
        $this->addtoDB("00000", $value, $randno);
    }
    foreach($arr as $k => $v){
        return $this->sendmsms($v);
    }

When I echo it, it perfectly displays but through DB its going just 1 batch. What could be the reason?

Answer 1

One solution that comes to mind is using array_chunk() to break $rmobiles into multiple arrays with a maximum of 150 elements each. Not sure if your sendmsms function takes a string or an array, but something like this may get you on the right track:

$mobiles = "9844700001,9844700002,9844700003,9844700004;...";
$rmobiles = preg_split('/[\ 
\;\:\,]+/', $mobiles, -1, PREG_SPLIT_NO_EMPTY);
foreach (array_chunk($rmobiles, 150) as $batch) {
    $this->sendmsms(implode(',',$batch));
}
