AFT*_*AFT 9 php sms encoding ascii ucs2
我正在寻找一个php中的代码/ lib,我会调用它并将文本传递给它,它会告诉我:
你知道任何代码/ lib存在会为我做这个吗？
我再也不想发送短信或转发短信,只是为了给我提供有关短信的信息
更新:
好的,我做了下面的代码,似乎工作正常,如果你有更好的/优化的代码/解决方案/ lib,请告诉我

print $text . "\n";
print isGsm7bit($text). "\n";
print getNumberOfSMSsegments($text). "\n";
function getNumberOfSMSsegments($text,$MaxSegments=6){
/*
http://en.wikipedia.org/wiki/SMS
Larger content (concatenated SMS, multipart or segmented SMS, or "long SMS") can be sent using multiple messages,
in which case each message will start with a user data header (UDH) containing segmentation information.
Since UDH is part of the payload, the number of available characters per segment is lower:
153 for 7-bit encoding,
134 for 8-bit encoding and
67 for 16-bit encoding.
The receiving handset is then responsible for reassembling the message and presenting it to the user as one long message.
While the standard theoretically permits up to 255 segments,[35] 6 to 8 segment messages are the practical maximum,
and long messages are often billed as equivalent to multiple SMS messages. See concatenated SMS for more information.
Some providers have offered length-oriented pricing schemes for messages, however, the phenomenon is disappearing.

我在这里添加一些额外的信息，因为先前的答案不太正确。
mb_strlen只会将此视为一个字符。到目前为止，我想到的是计算7位字符的方法：
// Internal encoding must be set to UTF-8,
// and the input string must be UTF-8 encoded for this to work correctly
protected function count_gsm_string($str)
{
// Basic GSM character set (one 7-bit encoded char each)
$gsm_7bit_basic = "@£$¥èéùìòÇ\nØø\rÅå?_?????????ÆæßÉ !\"#¤%&'()*+,-./0123456789:;<=>?¡ABCDEFGHIJKLMNOPQRSTUVWXYZÄÖÑܧ¿abcdefghijklmnopqrstuvwxyzäöñüà";
// Extended set (requires escape code before character thus 2x7-bit encodings per)
$gsm_7bit_extended = "^{}\\[~]|€";
$len = 0;
for($i = 0; $i < mb_strlen($str); $i++) {
if(mb_strpos($gsm_7bit_basic, $str[$i]) !== FALSE) {
$len++;
} else if(mb_strpos($gsm_7bit_extended, $str[$i]) !== FALSE) {
$len += 2;
} else {
return -1; // cannot be encoded as GSM, immediately return -1
}
}
return $len;
}
mb_convert_encoding($str, 'UTF-16', 'UTF-8')。
mb_convert_encoding）count(unpack('C*', $utf16str))并除以2，以得到计入GSM多段长度的UCS-2 16位字符的数量* caveat emptor，一个用于计数字节的单词：
strlen计数的字节数。尽管它可能会起作用，但strlen在具有多字节功能的版本的PHP安装中通常会过载，并且将来还会更改APImb_strlen($str, 'UCS-2')。虽然它目前可以正常工作，并且会为一堆便便字符正确返回2（因为它看起来像两个16位UCS-2字符），但是mb_convert_encoding当从> 16位转换为UCS-2时，其稳定状态是有损的。谁说mb_strlen将来不会有损？mb_strlen($str, '8bit') / 2。它目前也可以使用，并且建议在PHP文档注释中将其作为计数字节的方法。但是，IMO与上述UCS-2技术存在相同的问题。unpack荷兰国际集团到一个字节数组，并计算这一点。那么，这是什么样的呢？
// Internal encoding must be set to UTF-8,
// and the input string must be UTF-8 encoded for this to work correctly
protected function count_ucs2_string($str)
{
$utf16str = mb_convert_encoding($str, 'UTF-16', 'UTF-8');
// C* option gives an unsigned 16-bit integer representation of each byte
// which option you choose doesn't actually matter as long as you get one value per byte
$byteArray = unpack('C*', $utf16str);
return count($byteArray) / 2;
}
function multipart_count($str)
{
$one_part_limit = 160; // use a constant i.e. GSM::SMS_SINGLE_7BIT
$multi_limit = 153; // again, use a constant
$max_parts = 3; // ... constant
$str_length = count_gsm_string($str);
if($str_length === -1) {
$one_part_limit = 70; // ... constant
$multi_limit = 67; // ... constant
$str_length = count_ucs2_string($str);
}
if($str_length <= $one_part_limit) {
// fits in one part
return 1;
} else if($str_length > ($max_parts * $multi_limit) {
// too long
return -1; // or throw exception, or false, etc.
} else {
// divide the string length by multi_limit and round up to get number of parts
return ceil($str_length / $multi_limit);
}
