用PHP拆分长字符串用于发送SMS

Question

我的客户正在寻找一种方式来发送一条短信给我编程的Twilio脚本，然后让它重新广播给现场人员。这是很简单的部分，只需检查输入号码是否被授权，从MySQL中提取人员详细信息，并分发。

这里有一个棘手的部分--使用这款手机的人可能会长时间呼吸，他们的手机允许他们输入超过160个字符。假设Twilio可以接收>160个字符(我知道它不能发送>160个字符)，我需要将这条长消息(字符串)分解成块，这些块位于160个字符以下。

下面是我想出的脚本，它工作得很好，但我希望它以完整的单词结尾，而不是在拆分后的下一个字符。有趣的是，当您忘记输入拆分字符串的长度时，您将收到171条左右的字符短信！:P

<?php
$string = "Ulysses, Ulysses - Soaring through all the galaxies. In search of Earth, flying in to the night. Ulysses, Ulysses - Fighting evil and tyranny, with all his power, and with all of his might. Ulysses - no-one else can do the things you do. Ulysses - like a bolt of thunder from the blue. Ulysses - always fighting all the evil forces bringing peace and justice to all.";
$arr = str_split($string, 155); //Factoring in the message count
$num = count($arr); //See how many chunks there are

$i = 1; //Set interval to 1
foreach ($arr as $value) {
    if ($num > 1) {
    echo "($i/$num) $value<br/>"; //(x/x) Message...
    $i++;
} else {
    echo $value; //Message...
}

}
?>

非常感谢

更正抱歉，这是我的主要疏忽--我发布了开发脚本来播放字符串，而不是在“事件”之后发送实际短信的实时脚本。我需要能够迭代各块，然后将它们作为自己的SMS发送出去，就像上面提到的那样。只是以一个完整的词结束。短信将在前端循环中发送。

我不明白为什么你可以用：

$chunks = explode("||||",wordwrap($message,155,"||||",false));
$total = count($chunks);

foreach($chunks as $page => $chunk)
{
    $message = sprintf("(%d/%d) %s",$page+1,$total,$chunk);
}

这将产生如下情况：

尝试单词包装：http://www.php.net/manual/en/function.wordwrap.php

<?php

$words = "this is a long sentence that needs splitting";


foreach(explode("\n", wordwrap($words, 10, "\n")) as $s) {
        echo $s . "\n";
}

您可以首先使用空格作为分隔符，爆炸()字符串。一旦有了数组，就开始循环遍历它，然后一个一个地将单词添加到字符串中。在将单词添加到字符串之前，检查字符串的总长度是否超过160。如果是，启动一个新字符串。您可以通过存储字符串数组来做到这一点。

<?php
$string = "Ulysses, Ulysses - Soaring through all the galaxies. In search of Earth, flying in to the night. Ulysses, Ulysses - Fighting evil and tyranny, with all his power, and with all of his might. Ulysses - no-one else can do the things you do. Ulysses - like a bolt of thunder from the blue. Ulysses - always fighting all the evil forces bringing peace and justice to all."

$arr = explode(' ', $string); // explode by space
$msgs = array(); // array of finished messages

$i = 0; // position within messages array
foreach($arr as $word)
{
    if (strlen($msgs[$i] . $word) <= 155) // this may be 160, im not sure
    {
        $msgs[$i] .= $word;
    }
    else
    {
        $i++;
        $msgs[$i] = $word;
    }
}
?>
