不是alery的警报。

Seems like a simple typo. You're missing a double-quote.

看起来是一个简单的错误。你错失了一个双引号。

What version of PHP are you running?

您运行的是什么版本的PHP ?

Could you try echoing something else after: $testObject->split_for_sms($Chat);

您可以试着重复其他的东西:$testObject->split_for_sms($Chat);

Maybe it doesn't get to that part of the code? You could also try these with the other function calls to check where your program stops/is getting to.

也许它没有达到代码的那一部分?您也可以尝试使用其他函数调用来检查程序在哪里停止。

Hope you get a bit further with this.

希望你能更进一步。

When you use javascript tag in echo function, It can be misleading because of "quotation" signs in php echo function. I suggest you to close tag!

当您在echo函数中使用javascript标记时，由于php echo函数中的“引号”符号，它可能会产生误导。我建议你关闭标签!

  <?php  
  header("Location:form.php");
   ?>
  <script type="text/javascript">
     alert("message successfully sent"); 
  </script>
  <?php
  exit;
  ?>
