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

echo '<script language="javascript">';
This should do.

When I just run this as a page
当我把它作为一个页面运行时
<?php
echo '<script language="javascript">';
echo 'alert("message successfully sent")';
echo '</script>';
exit;
it works fine.
它工作正常。
What version of PHP are you running?
您运行的是哪个版本的 PHP？
Could you try echoing something else after: $testObject->split_for_sms($Chat);
您能否尝试在以下之后回显其他内容： $testObject->split_for_sms($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.
也许它没有到达代码的那部分？您还可以尝试使用其他函数调用来检查程序停止/到达的位置。
Hope you get a bit further with this.
希望你能更进一步。
