前几天老板拿来一个短信收发设备,让我用php做一个发短信的程序,哎,我可是菜鸟,什么都不懂,网上查了很多资料,终于找到了方法:php通过调用串口直接用 短信收发设备来发短信。
不过虽然源程序在手,但还是不能直接用,期间碰到很多很多问题,发中文短信啊,缺少dio库啊,最后还是解决了。我把代码贴出来,大家有需要的可以参考一 下:
注意几点:
1.必须要有php_dio.dll这个文件,原来我的php是5.2.1的,因为php在5.0的时候已经把dio给去掉了,所有不能用串口了, 说是放在pecl库里了,哎,网上找了半天,才找到php5.2.6和pecl5.2.6,把自己的版本也更新到5.2.6,这样就可以调用串口了
2.发中文遇乱码的问题,在测试的时候都是乱码,后来发现我的文件是utf-8的,改成gb2312就好了
以下是我的程序,我把一些不要的东西去掉了,但可以发短信,在xp+apache+php5.2.6测试成功!
1.<?php
header('Content-type: charset=gb2312');
function gb2unicode($str) {
return iconv("gb2312", "UCS-2", $str);

for($i=0; $i<strlen($hexstring); $i++){
$str .= sprintf("%02X",ord(substr($hexstring,$i,1)));
}
return $str;
}
function InvertNumbers($msisdn) {
$len = strlen($msisdn);
if ( 0 != fmod($len, 2) ) {
$msisdn .= "F";
$len = $len + 1;
}
for ($i=0; $i<$len; $i+=2) {
$t = $msisdn[$i];
$msisdn[$i] = $msisdn[$i+1];
$msisdn[$i+1] = $t;
}
return $msisdn;
}

$pdu_text = hex2str(gb2unicode($sms_text));
$invert_msisdn = InvertNumbers($msisdn);
// 拆分发送超?0汉字的短?todo: 没有判断全英文的情况)
do {

if ( $pdu_len > $max_len ) {
$pdu_text1 = substr($pdu_text, 0, $max_len);

PHP编程:通过串口+GSM MODEM发送短信示例
公司有发短信任务,!@#$%^&~。每月至少500条,还要发给不同的50个人,ft!刚好看到版主HQ的大作 《[硬件 通讯]PHP在RS232串口通讯协议的应用演示[测试环境PHP5.1.4]》,周末写一个群发短信的小脚本,2.5小时发1000条,超额完成任务, 嘿嘿!贴上来凑个热闹。
