Three practical PHP message functions

Because there is no msgbox, PHP programs often use JavaScript+DOM to pop up message boxes or jump to web pages. During the development of the Shuguang examination platform, in order to reuse the code, a simple function was written and saved in a file, which can be referenced when needed. Although it is a bit childish, it is economical and practical.

/*1. Pop-up message*/
function aler($msg)
{
 echo "";
}

/*3. Delay for the specified number of seconds and then jump to the specified webpage*/
function goto($tim,$goto)
{
 echo "";
}


/************************
//Application example
aler("Thanks for browsing!");
msge("Sorry, need to start again!");
msge("Welcome!","http://www.sgksw.net");
goto(5,"http://www.sgksw.net");
