Php automatically sends short messages

Php itself has no function of making phone calls and sending and receiving short messages!

However, some of these operators can provide some api interfaces that php can call!

However, it costs money to successfully call their interfaces!

For example, you spent 100 yuan to buy one of their packages, which contained 1000 text messages!

Then your php successfully calls their api interface once and successfully sends short messages!

Then reduce the remaining text messages by one!

When your package information is 0, your call will fail again!

Continue to buy SMS!

Anyway, it's for money!
